Uniform Rounded Corners - Cool Code

A client sent a design for a Word template that had lots of boxes and photos with uniform rounded corners. Not an unreasonable request, but Office doesn't do that well. In PowerPoint, Word and Excel, rounded corners are proportional to the size of the shape. Making them uniform manually is picky and time-consuming. But with a dash of VBA, we can make the job easy.


The Math

As a round-cornered shape gets larger, the corner radius increases as well, in proportion to the shape size. Since we want to keep the radius the same size, we need to create a formula that makes a smaller number as the height and width increase. We need an inverse number! The simplest way to create an inverse is to divide 1 by the measurements. Then, we need a number to set the radius size: a constant. The formula looks like this: (1 / (Shape.Height + Shape.Width)) * RadiusFactor. And you thought you'd never need that high school math!

Here's VBA code that will work in Excel, Word and PowerPoint on a selection of round-cornered boxes:

Sub RoundedCorners()
  Dim oShape As Shape, RadiusFactor!
  RadiusFactor! = 50
  For Each oShape In ActiveWindow.Selection.ShapeRange
    With oShape
      If .AutoShapeType = msoShapeRoundedRectangle Then
        .Adjustments(1) = (1 / (oShape.Height + oShape.Width)) * RadiusFactor!
      End If
    End With
  Next oShape
End Sub

Uniform Rounded Corners for the Whole Document

To run this on a whole presentation, document or workbook, we need to customize the routine for each Office program. Here's the Excel version:

Sub RoundAllXLCorners()
  Dim oWorksheet As Worksheet, oShape As Shape, RadiusFactor!
  RadiusFactor! = 50
  For Each oWorksheet In ActiveWorkbook.Worksheets
    For Each oShape In oWorksheet.Shapes
      With oShape
        If .AutoShapeType = msoShapeRoundedRectangle Then
          .Adjustments(1) = (1 / (oShape.Height + oShape.Width)) * RadiusFactor!
        End If
      End With
    Next oShape
  Next oWorksheet
End Sub

To do the same in PowerPoint

Sub RoundAllPPCorners()
  Dim oSlide As Slide, oShape As Shape, RadiusFactor!
  RadiusFactor! = 50
  For Each oSlide In ActivePresentation.Slides
    For Each oShape In oSlide.Shapes
      With oShape
        If .AutoShapeType = msoShapeRoundedRectangle Then
          .Adjustments(1) = (1 / (oShape.Height + oShape.Width)) * RadiusFactor!
        End If
      End With
    Next oShape
  Next oSlide
End Sub

And finally, for Word

Sub RoundAllWDCorners()
  Dim oShape As Shape, RadiusFactor!
  RadiusFactor! = 50
  For Each oShape In ActiveDocument.Shapes
    With oShape
      If .AutoShapeType = msoShapeRoundedRectangle Then
        .Adjustments(1) = (1 / (oShape.Height + oShape.Width)) * RadiusFactor!
      End If
    End With
  Next oShape
End Sub
Before: Rounded Corners, but not Uniform
Rounded Corners, but not Uniform

The Word version is a little simpler because a Word document is one big object, while Excel and PowerPoint both have multiple objects for each worksheet and slide, respectively. But the similarites point out that when you're searching online for VBA code, finding something for a different program and modifying it can be a huge time-saver. By far, Excel has way more code written for it, so Excel VBA sites can be a fruitful source for Word and PowerPoint code ideas.

These macros have been tested under both Windows and macOS and work well under both.

Shared Workgroup Templates - Best Practices

Groups of workers usually use the same templates. But it can be time-consuming to keep everyone updated when templates are installed separately on each desktop. Instead, you can implement shared workgroup templates with a feature already built into Office.


Shared Workgroup Templates - Multiple Uses

Every desktop version of Office, Mac and Windows, includes a Workgroup templates option that allows you to set a network share as a templates folder. Templates on this share are instantly available to all users, making updates and revisions a breeze. Automatically, everyone in the office is using the same version. As long as template names remain identical, then old Word documents automatically attach themselves to the new template.

The Workgroup templates network share can serve more that just templates. With some additional subfolders, it can be a source for Document Themes, including custom SuperThemes, it can hold collection of Font and Color themes. These additional files don't show in the File>New dialog. Theme files display under the Themes dropdown, theme colors under the Colors dropdown and theme fonts under the Fonts dropdown.


Shared Workgroup Templates - Setup

To set up shared workgroup templates, first create the network location and ensure it's accessible to all in the office without a signin. Each computer should connect to the share automatically on restart, so users don't have to remember to manually connect before creating a new document. Create subfolders with the following names for othe file types you want to support. Document Themes for themes, with subfolders for Theme Colors and Theme Fonts. All versions of Office expect exactly the same file structure.

If the office uses Group Policies to install and configure software, you can use that feature to add the Workgroup Template location to each user installation. If you're using "sneakernet" for configuration, here's how to do it manually. All Office suites use a setting in Word to set the location for all the other programs

Shared Workgroup Templates - Shortcomings

In addition to templates and themes, a local templates folder also serves custom Chart and SmartArt templates. Neither of these formats is supported by Workgroup Templates, so those templates must still be installed locally on each user's computer.

OOXML Hacking: Fix Broken PowerPoint Links

Please note: Microsoft has modified the nature of OLE links. It's no longer possible to create relative OLE links (linked Excel and Word) in current versions of Office. If you're relinking using absolute paths, or relinking other object types, like images, audio or video, this article will still work for you.

Someone sends you a presentation linked to an Excel file. The links don't work and you can't fix them without redoing them. Here's how to fix broken PowerPoint links with a one minute of XML Hacking.

This article is really just for PowerPoint for Mac users. If you have the Windows version, you can fix broken links by choosing File>Info, then clicking on Edit Links to Files in the right-hand column under Related Documents. (Please note, the Edit Links option only appears if you actually have a link in the open presentation.) Word and Excel for Mac already have utilities to fix links.

If you haven't hacked XML before, please read XML Hacking: An Introduction and XML Hacking: Editing in macOS. This article mentions Excel, which I've used as an example, but the same advice is true for Word files linked to PowerPoint. OLE Links to other formats, like PDF, are simply not supported on macOS.

In Office, links to documents include the complete path. Of course, when you move those linked files to a new computer, the path is always different, so the links must be corrected. The symptoms of a broken link depends on the type of link that was created. If the file creator selected a workbook section or chart, then used Paste Special to paste in a link, you'll see this message when you double-click on the Excel excerpt:

Fix Broken PowerPoint Links - Paste Special

But the creator may have used Insert>Object instead, and chosen to link rather than embed the file. Then you'll see this when you try to edit:

Fix Broken PowerPoint Links - Inserted Object

Then after dismissing that dialog, you'll see the first one about the server error.


Fix Broken PowerPoint Links - The Steps

The issue is that a path is embedded in the PowerPoint file, and that path must be edited. Open the file in BBEdit.

The XML we need to change is associated with the slide(s) on which the Excel item is placed. So lets look. In the left-hand window, click on ppt. Then select slides then the _rels folder. Rels is short for relationships, and it's the mechanism in every OOXML folder that tells PowerPoint where to find the objects in use.

The _rels folder has a .rels file for each slide in the presentation. Open the file for the slide containing the linked Excel. If the link was inserted using Paste Special, it will look like this (Pay attention to the third line and scroll all the way to the right. The path to be edited is in bold):

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
  <Relationship Id="rId3" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/oleObject" Target="file:///\\192.168.1.250\Dockets\Test\Excel\Link2PowerPoint.xlsx!Sheet1!R1C1:R1C4" TargetMode="External"/>
  <Relationship Id="rId2" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/slideLayout" Target="../slideLayouts/slideLayout7.xml"/>
  <Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/vmlDrawing" Target="../drawings/vmlDrawing1.vml"/>
  <Relationship Id="rId4" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/image" Target="../media/image1.emf"/>
</Relationships>

If the Excel file has been inserted as an linked object, it won't include a range of cells, just the workbook name:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
  <Relationship Id="rId3" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/oleObject" Target="file:///\\192.168.1.250\Dockets\Test\Excel\Link2PowerPoint.xlsx" TargetMode="External"/>
  <Relationship Id="rId2" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/slideLayout" Target="../slideLayouts/slideLayout7.xml"/>
  <Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/vmlDrawing" Target="../drawings/vmlDrawing2.vml"/>
  <Relationship Id="rId4" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/image" Target="../media/image2.emf"/>
</Relationships>

Since the Excel item was inserted on a Windows computer, the path uses backslashes instead of forward slashes. There are two path syntaxes that are acceptable. If both the file linked to and the presentation containing the link are in your User folder, you can use a relative path and the linked file will open up immediately. If the file linked to is on a network share or somewhere on your disk outside your user folder, you will have to use an absolute path and you will get a challenge from Office when you open the link.

Let's do the relative path first. In this example, the Excel file is in my user Documents folder and the PowerPoint is in my user Downloads folder. So I edit:

Target="file:///\\192.168.1.250\Dockets\Test\Excel\Link2PowerPoint.xlsx"

to:

Target="file:///../Documents/Test/Excel/Link2PowerPoint.xlsx"

In Unix/DOS speak, the 2 dots mean "go up one level", out of the Downloads folder where the presentation is into the main user folder. Then the slashes lead you down into the Documents folder and subfolders to the Excel location. Once you set a relative path, you must leave the PowerPoint file in the same folder. Moving it will break the path.


Fix Broken PowerPoint Links - The Best Relative Path

For a linked file that you know will be moved from desktop to desktop, the best strategy is to place both files in the same folder. Then use this path:

Target="file:///Link2PowerPoint.xlsx"

Now even if you shuffle it between Mac and Windows, the linked Excel file will open as expected without having to edit the links at all!


Fix Broken PowerPoint Links - Absolute Paths

If the file to be linked to is on another disk, use an absolute path. With an absolute path, you can move the PowerPoint file anywhere on your computer or to other machines and it will still be able to find the linked file. Here's what an absolute path looks like:

Target="file:///Volumes/TheNameOfYourHardDisk/Users/YourUserName/Documents/Test/Excel/Link2PowerPoint.xlsx"

Important! A macOS absolute path must begin with Volumes, followed by a slash and the name of the disk. If your network is set up for different operating systems, you'll probably use an IP address instead, as shown in the original file path. Consult with your IT department.

Office 2016 for Mac applications are sandboxed applications, so when you first open an Office file linked with an absolute path, you'll see a warning:


Fix Broken PowerPoint Links - Absolute Path Warning 1

Click on Select..., then you'll see:

Fix Broken PowerPoint Links - Absolute Path Warning 1

Select the correct file if it isn't already selected, then click on Grant Access. Now double-click on the linked Excel item to edit and you'll see this again:

Fix Broken PowerPoint Links - Edit Warning

OK, that's something of a hassle, but the good thing is that you won't see those warnings again as long as the linked file says in the same place with the same name. You also only get warned once per placed file, even if there are multiple uses of that file in your presentation.

Linked files are a huge benefit when you have a data source that is constantly being updated. Using them means your presentation can always be up to date. Now that you know how to fix the links, you have a very useful new tool.

The Flat Theme - Best Practices

Flat Theme Shape Styles

I'm writing an article or two about Office Effects Themes and how you can modify them. As an example, I created the Brandwares Flat Theme, which will be of use to designers as is. This theme file gets rid of the bulgy 3-D shapes, glows and hokey shadows of the standard Microsoft themes and relies only on tints, shades and outline variations. You can use this example in 2 ways: as a theme file that you can modify and send as your own, and as an Effects Theme file that can be installed in Office for Windows to provide access to flat shapes in all other themes.

Here you can download the Flat Theme. It's also available on our Downloads page. After downloading, you can open it in PowerPoint, create new font and color themes, apply them, then resave as a new theme. The flat shapes will travel with the theme and be automatically applied to any deck that uses the theme. If you're an Office for Mac user, you'll have to create a font theme using this article: XML Hacking: Font Themes.


The Flat Theme - Specs

There are 7 variants in each row of the the Shape Styles dialog, each showing the dk1 color as a background plus the 6 Accent colors. The first 2 rows feature a 0.5pt outline on the shape in a darker variant of the accent color, with the first row showing a white shape background and the second row the relevant accent color.

The third row is the one I choose most of the time: a flat shape with no outline.

The fourth row has a 50% screened-back background color with black text.

The fills for the 5th and 6th rows are 2 progressively darker shades of the accent colors. The 5th row shows a 50% shade of the color, while the 6th is a two-layer multiplier fill with a 50% shade overlaying a 50% tint. I'll explain these more in the articles to come.

Users of Office 2016 for Windows and for Mac will see an additional group of Presets below the theme shape styles. Except for the stroke weight in row 2, these fills are generated automatically by the program and cannot be modified by XML.


The Flat Theme - Installing as Effects Theme

You can also use the Flat Theme as a new effects theme in Windows versions of Excel, PowerPoint or Word (Office for Mac will display effects themes embedded in a theme or template, but there is no support in the program interface for applying a different effects theme). Then it will appear in the Theme Effects dropdown of Office for Windows along with the standard Microsoft themes. Here are the steps to do that:

  1. Download the Flat Theme from the link above and unzip it.
  2. Change the file name from BrandwaresFlatShapes.thmx to Flat.eftx. The first part of the name can be something other than Flat, but the ending must be .eftx. No other change to the theme file is needed.
  3. Close PowerPoint.
  4. Copy the file to the same folder as the Microsoft Theme Effects files:

32-bit PowerPoint 2007: C:\Program Files (x86)\Microsoft Office\Document Themes 12\Theme Effects

64-bit PowerPoint 2007: C:\Program Files\Microsoft Office\Document Themes 12\Theme Effects

32-bit PowerPoint 2010: C:\Program Files (x86)\Microsoft Office\Document Themes 14\Theme Effects

64-bit PowerPoint 2010: C:\Program Files\Microsoft Office\Document Themes 14\Theme Effects

32-bit PowerPoint 2013: C:\Program Files (x86)\Microsoft Office\root\Document Themes 15\Theme Effects

64-bit PowerPoint 2013: C:\Program Files\Microsoft Office\root\Document Themes 15\Theme Effects

32-bit PowerPoint 2016 and 2019: C:\Program Files (x86)\Microsoft Office\root\Document Themes 16\Theme Effects

64-bit PowerPoint 2016 and 2019: C:\Program Files\Microsoft Office\root\Document Themes 16\Theme Effects

With Office 2013 and 2016, there may not be a root folder, but then the Document Themes folder will be inside Microsoft Office, eliminating one level.

Restart PowerPoint and you'll see a new addition to the Effects dropdown:

Using the Brandwares Flat Shapes theme as an Effects Theme

Great Color Themes - Best Practices

Great color themes in Office are not a random collection of swatches. Each spot in a color theme has a job. Once you learn those functions, great color themes will roll out from your office.

I'm always astounded to hear a Office "professional" who says "I don't use themes." I'm amazed because in modern versions of Office it's impossible to not to use themes. If you haven't set a theme for your template, then you're using the default Office theme. Whether you like it or not! Themes are an integral part of Office, so you'd better learn how they work.

I've previously covered Font Themes and how to hack them, a necessary skill for macOS creators. Check out XML Hacking: Font Themes and XML Hacking: Font Themes Complete. In this post, I'm covering the inner workings of theming to show you how to create great color themes. I've touched on this subject previously in Office Charts: 6 Colors Maximum! For ideas on how to include more than one color theme in a template or presentation, please see XML Hacking: Color Themes


Great Color Themes: The Basics

When you create a color theme in PowerPoint, the color set is added to the theme1.xml file in your presentation and it's saved on your computer. If you create a second color theme, that theme is also saved to your computer, but it replaces the first one in your deck. When you're using the user interface, each Slide Master has only 1 theme at a time. So for more color themes, create more slide masters. If the color theme is for a special purpose, like differently-colored charts, the extra slide master might have only 1 slide layout. That's less confusing for users.


Great Color Themes: Color Slot Functions

Almost every slot in a color theme has a PowerPoint function, a job that it fulfills for the program. If you don't know what these are, you'll place the wrong color in the slot and get a result that looks weird in the program interface. Needless to say, this doesn't help your professional cred with your client.

Here's the Color Theme editing dialog as seen in PowerPoint 2016 for Mac. In Office for Mac, you can only create color themes in PowerPoint. In Windows versions, you can create them in any Office program, though there is a good reason why you should still use PowerPoint.

Color Theme Editor

The following advice covers standard presentations that have a light background and dark text. If you're going for the mysterious Mafioso look with a dark background, then reverse the following instructions putting text colors into the light slots and backgrounds into the dark ones. Oddly enough, when PowerPoint imports a theme exported from Word for Excel, it will default to the Mafioso look. This is the good reason why you should always export theme files from PowerPoint, where your choices for background and text are explicit and that information is preserved in the theme.

The first 4 colors are for text and backgrounds. Although all 4 are called Text/Background, that just to accommodate the occasionally light text on a dark ground, as mentioned in the previous paragraph. In reality, Dark 1 is the main text color. If you have black text in the deck, leave this set at black. You should only change this if you have no black text (Please dont't tell me you're doing that trendy look of black text that's dark grey and makes it look like your printer ran out of toner. Eww.)

You may have a secondary text color for headings. That must go in the Dark 2 slot. Not in Light 1! Not in Light 2! All text colors go in the dark slots!

Light 1 is for background colors. Most of the time, this is white, so leave Light 1 set at white. If the design calls for a different background color than white, set it here.

Light 2 is the only slot in the theme that doesn't have a secondary job. You can make this slot any color! It doesn't matter! Woo-hoo! Let's hold off, this is a good spot for an extra color that doesn't fit elsewhere.

Accent 1 is the default color for inserted SmartArt, Text Boxes and Shapes. Almost all the time, you will make Accent 1 the primary corporate color. For our company, PMS 481C is the code color, so Accent 1 is the RGB equivalent in all our company themes.

If the company has a secondary brand color, Accent 2 is the logical position for it. So what about Accents 3 to 6? You're thinking "Hey! 4 empty slots! Throw some colors in, we're done!" Not so fast, junior.


Great Color Themes: Chart Fills

The set of Accent colors have a huge responsibility of their own: chart fills! I've created a color sequence to show how these are applied by PowerPoint.

Office programs fill charts using these 6 six colors in sequence. So when you're designing, it's best to know what that sequence is. The colors will be used in the same order:

Left to Right for Column Charts
Great Color Themes - Column Chart
Bottom to Top for Bar Charts
Great Color Themes - Bar Chart
First to Last for Line Charts
Great Color Themes - Line Chart
From 0 degrees (top dead center) clockwise for Pie Charts
Great Color Themes - Pie Chart

If there are no additional colors in the design standards, we create a pair of lighter and darker variations of the brand colors for Accents 3 to 6. But don't just create a pretty series of swatches! Is the chart readable when printed on a black and white laser? Can color-blind people read it? You're a Designer! You're supposed to be thinking of these things! The rule of thumb is to alternate darker and lighter colors in a sequence so they can be distinguished from one another even in monochrome. Not sure? Test it!

Of the 12 colors in the theme, only the first 10 are accessible to the user in color picker dialogs. The last 2, Hyperlink and Visited Hyperlink, are applied automatically when the user inserts a hyperlink in the document. I usually use 2 of the theme colors for these, rather than Microsoft's standard colors. If there's a blue, that's a good choice for the hyperlink, it's a visual cue. The followed hyperlink can be a lighter grey or other tint, if there is one in the palette.


Great Color Themes: Recognizing Trouble

Before shipping the deck, here are a few quick tests you should be performing to show any color theme problems:

Insert SmartArt: Is the text readable?
Smart Art Problem
Insert a chart: Does the preview look right?
Chart Preview Problem

If either of these look odd, you probably have a color theme problem. If the text or background of either the chart preview or SmartArt don't match the background of the deck, you've probably inserted a dark color into the Light1 slot

Insert a table: Do the auto-generated variations contain many useless combinations?
Table Colors Problem

Most of the autogenerated table combinations in this example are hideous and unworkable, sure sign of a bad color theme. You may also see a table style preview that looks different from the actual table. If the table preview shows a different color for table text (it will just show colored lines, not actual text), then the colors in Light2 and Dark2 have to be switched. Another problem indicator is if it appears you are selecting one color in the picker, but the actual color applied is different.

Insert a chart in Excel: Does the chart background match the worksheet background?
Excel Insert Chart Problem

If you see any of the above symptoms, take the time to fix them and do it right. Your client will notice these glitches and you won't be able to 'splain them away.

The general method to fix these issues is to put the theme in correct order, then go through the entire deck starting with the Slide Masters, correcting the colors back to the designed appearance. This effort isn't too bad if it's a single template or theme you're correcting. Groups of finished presentations are a different matter that need a more automated approach. Next time, I'll be writing about how to repair presentations with a bad color theme, using XML Hacking.

OOXML Hacking: Recent Colors

Recent colors are handled inconsistently by Microsoft Office programs. Word and Outlook only retain recently used colors only as long as the program is running, and those colors are visible in every document that's open. By contrast, PowerPoint and Excel both include them in the document. As soon as you open a different file, the previous colors disappear from the color picker. Return to the first document and there they are again.

If you're creating files for clients, you may generate quite a few colors in the design process. Your work will look a little more professional if you purge the Recent Colors from the PowerPoint or Excel file before sending it on.

If you're new to XML hacking, please read my intro: XML Hacking: An Introduction. If you're working on a Mac, you should also read XML Hacking - Editing in macOS.

Recent Colors in the Windows Color Picker

The row of Recent Colors that PowerPoint and Excel include in the file is a distraction for your client.


Recent Colors Removal Steps

Under Windows, begin by unzipping the file. On a Mac, open it in BBEdit or other advanced text editor.

If this is a PowerPoint deck, look in the ppt folder for the presProps.xml file. The recent colors begin on the third line of a prettified (human-readable) file. Simply delete the entire clrMru section:

<p:clrMru>
  <a:srgbClr val="A54DA5"/>
  <a:srgbClr val="C8006E"/>
  <a:srgbClr val="64006E"/>
</p:clrMru>

To remove the Recent Colors from an Excel workbook, open the xl folder, then edit styles.xml. Look for the colors section, then delete the entire mruColors part:

<colors>
  <mruColors>
    <color rgb="FF640064"/>
    <color rgb="FF393939"/>
  </mruColors>
</colors>

After editing, rezip the files if you're using Windows or save and close in your macOS text editor. Test that the file opens as expected and no longer has Recent Colors in the color picker, that send it off to the client.

Recent Colors Removed

A more presentable dialog for your client.


Don't Reuse Recent Colors

Occasionally an artist will try to include special colors in the Recent Colors section, to give the client some additional color choices. This is a bad idea because the Recent Color section is dynamic. When any new color is created, it's added to the left end of Recent Colors. If the row is full, the oldest color gets pushed off the right end. A better solution is to create Custom Colors. Here's my how-to on the subject. Custom Colors don't move or change and can be named, which is a little extra help for your client.

Choosing Fonts for Office - Best Practices

When you choose fonts for Office, it takes a different approach than selecting typefaces for an InDesign document. One obvious difference is that you only need to install the font for a design document on the computer where it's being created. Using the same font in an Office program will require the font to be installed on every computer using the document. Clearly, this is a much more costly solution. Aside from that, let's look at the pitfalls of choosing fonts for Office templates.


Choosing Fonts for Office - Fake News

Most of what you see on the internet comparing font formats is wrong. Almost all modern professional fonts are OpenType format. There is PostScript-flavor OpenType, favored by Adobe and ending with .OTF And there is TrueType-flavor OpenType, Microsoft's choice, ending with .TTF. It's the continued use of the .TTF file ending that has misled many into thinking that they're old-fashioned TrueType fonts. They're not.

To verify this in macOS, open FontBook and examine a font with a .TTF ending. Make sure choose View>Show Font Info. Now look at the Kind parameter. Old-fashioned TrueType fonts would say TrueType here, but more likely you're seeing OpenType TrueType.

In Windows, if you right-click on any file ending in .TTF and choose Properties, Type of file is reported as TrueType font file (.TTF). But this is illustrative of Windows' relatively brain-dead design rather than any real information about the font.

Confirming this in Windows requires a few more steps. Start by opening the C:\Windows\Fonts folder. Set the View menu to Details. Now right-click in the row that displays the categories like Name, Font Style, etc. A list of avilable categories display. Choose Font Type. Now you can see that almost all the fonts are OpenType. You'll only see TrueType if you've installed some old fonts from the 90s.


Choosing Fonts for Office - Designer Vanity

Designers from different geographic areas spec fonts differently. As one example, Toronto designers tend to focus on the practicalities of electronic document distribution. As a result, they will often choose Arial or Times New Roman for the user-filled portion of a template. By contrast, designers from New York focus on creating a distinct visual appearance. They choose unusual designer fonts. This creates logistical problems for their clients. They must spend money licensing for all workstations and then take time to install the fonts for each user.

Test fonts from small foundries to licensing a lot of copies. I've written about this issue before: Cross-platform Fonts from Small Foundries: Beware! In a mixed Windows/OS X environment, a poor quality font will not display correctly in documents that move between Mac and PC. One typical symptom is Italic text that displays as Roman or Bold when viewed on a different OS, or some similar weight/style mixup.


Choosing Fonts for Office - Collaboration

If the client uses Office documents for collaboration (Don't know? You should be asking these questions!), you should seriously reconsider a "designer-y" font choice. When the documents arrive at your client's client, that computer will not have the fonts and the document appearance will change drastically. Unlike web pages, Office documents do not have a font fallback setting. There is no practical way to preset which font will be substituted when the original is missing.

I know what you're going to say next: "What about if we embed the fonts?" Here are several reasons why that might not work.

  • Embedding does not work at all in Office 2011 or earlier for Mac. Users of these versions can neither embed fonts, nor can they view fonts that have been embedded in Windows.
  • Embedding doesn't work in Word or Excel for Mac, in both the 2016 and 2019 versions. PowerPoint 2016 for Mac users must have at least version 16.11 to view embedded fonts. The 2016 retail version (as opposed to the Office 365 subscriber version) cannot embed fonts in PowerPoint. Mac users must have at least Office 2019 retail or Office 365 version 16.17 to save embedded fonts in a PowerPoint file.
  • Many typefaces have restrictive embedding permissions. So even if you can embed the font and your client can see it, they will not be able to edit the document using the embedded font. You can get around this if you contact the foundry and request a version with Editable or Installable permissions. Expect to pay a surcharge for this. Some foundries charge a lot for this service, because they're concerned about losing sales to possible piracy.

Choosing Fonts for Office - Font Families

Designers are used to Single versions of fonts. The is where each font variant appears as a separate entry in the font list in Office. If you want to change to bold or italic, you select a different font from the list. Office doesn't usually work this way and Office users are not used to this method.

When all four faces in a font family are installed, using the bold and italic buttons has the intended effect of switching fonts.
Choosing Fonts for Office - Font Family Installed

Instead, Office users are familiar with Family fonts. This is where where a group of (usually 4) fonts is linked. To get bold or Italic variants, they click on the Bold or Italic buttons, leaving the font name the same. The foundry usually creates the font families, though there are some type utilities available that let you make a family out of single fonts. As I mentioned earlier, Microsoft hasn't figured out how to consistently display an .OTF font family correctly. Symptoms vary but are along the lines of you choose Bold and you get Bold Italic, or a similar variant. The wrong font is shown and printed. Typocially this will manifest when moving a Windows-created document to macOS or vice versa.

If the font is not set up as a family-style font, then using the bold and italic buttons fakes the look with stroking and/or slanting the roman. The result is a disastrous visual effect.
Choosing Fonts for Office - Base Font Installed

In macOS, it's not obvious when you are using single versus family fonts. MacOS creates family groupings on the fly. In Windows, it's easy: install the fonts, then look at the font menu in an Office program. A font family will only have one entry for the family, while singles will list every font variant. In this screen shot, the Arials are families. Arnhem and ATC Arquette are collections of single fonts:

The Arials are families, while Arnhem and ATC Arquette are singles.
Choosing Fonts for Office - Windows Font Menu

The logical conclusion to the font family approach is that your client should almost never be licensing just one or two typefaces. If four family members are not installed, Office will fake them by stroking the font for bold and slanting it for italic. As you might guess, this looks ghastly and completely off-brand.

The exceptions to this rule are:

  • If the document is a fillable form in Word or Excel. Those documents are typically locked so the user can't change the font or its attributes.
  • The the font is used only for Headings. These are usually bold and stay that way, so there is less chance of a user applying attributes.

In either of these 2 situations, you should be able to get away with licensing a single typeface instead of a complete family.

A font family with all 4 members installed. The bold and italic button work as expected.

Here is a family-style font with only the Roman installed. Using the bold or italic buttons gets you this dreadful look, plus an out-of-memory warning from Office.
Choosing Fonts for Office - Roman only installed

If your design calls for an unusual mix of weights, like Light and Demibold instead of Regular and Bold, contact the foundry to request a custom family. There is normally a small charge for this service. However, if the licensing deal is large enough, the foundry may waive this.


Choosing Fonts for Office - 2 Solutions

To sum up, for each different font used in your design, your client should be licensing a complete family of 4 typefaces in TrueType or Truetype-flavored OpenType.

Brandwares is a font reseller and we've been speccing type for Office for years. If you choose us to create your templates, we can also source your client fonts in the correct format and family. This service includes free tech support. We'll help your client with any installation or usage issues and communicate with the foundry, if necessary.

Working on your own? A simple way to eliminate all these issues is to design with the fonts that are already installed by Office. There are many faces more interesting than Arial and Times New Roman in this collection. The fonts that come with Office don't require any additional licensing fee. They are already installed and they have relaxed embedding permissions to make collaboration easy. They are all high-quality typefaces licensed from major foundries like Monotype. Here is a list of the families that are useful for business communications (we left out Comic Sans!). For maximum compatibility among all versions of Office, use a font that is checked in every column.

Best Quality Logos for Office - Best Practices

It's a challenge to create the absolute best quality logos for client files in Microsoft Office. Most artists choose bitmap formats for logos, usually JPEG format. Apparently this is some kind of received wisdom from artist to artist, because JPEG format is close to the worst possible format for logos. But I've already covered this subject in JPEG Logos? Fail! back in 2013.

Brandwares has used indexed-color PNG format for most line art (a term for non-photographic art that is mostly flat color areas). Most logos qualify as line art. But there are a couple of disadvantages to using any type of bitmap format for branding information.

With Office files, Microsoft is determined to foist image "compression" on us. I put compression in quotes because Microsoft's solution is really downsampling by another name. Whatever the name, the results are blurry and absolutely do not reinforce the brand. All bitmap files will be downsampled unless the user chooses only a single file. You can't protect the company logo, even with XML hacking. Let's face it, sooner or later, bitmap logos will look like mush.

The other persistent problem with bitmap formats is what happens when you create a PDF from a document. Acrobat's default settings assume you want to create a small file to post on a web page. This was a serious problem 20 years ago. So, once again, a software company's helpful authoritarianism leads to default settings that cream the logos in any Office file.


Vector Formats for Best Quality Logos

For many years, we at Brandwares were aware that a vector format was a potential way out of this. Vector formats are naturals for line art, because they easily handle geometric shapes with simple coloring. But there are relatively few vector formats from which to choose, and the available formats didn't seem up to the job.

One grandaddy of vector formats is the EPS file. Well-known to designers, the EPS doesn't get great support in Office programs. Printing them at high resolution requires PostScript support from the printer, which is dicey in most business offices. Office programs can't ungroup them, so adding theme color support in an Office file is out of the question.

CGM was an early contender, and is still used in technical applications. But it never got support in common file formats. SVG is making inroads on the web, but Office is only beginning to support the format.

Let's be honest, Microsoft offers the best support to the formats it invents. For vector graphics, that is WMF and EMF. WMF is a 16-bit format that was invented in the '90s. In practice, it's not too useful today. All too often, WMF files do not render the inside curve of shapes like O or D. In addition, Adobe Illustrator's WMF export is horrendous, turning every curve into a series of angled straight lines. Corel Draw does a better export, but the format is limited by its 16-bit capacity.

The format we're left with is EMF (Enhanced MetaFile). Brandwares has developed a method to create the highest quality EMF files possible. Whatever you do, do not use EMFs exported by Adobe Illustrator! Illustrator's curve accuracy goes down the toilet when it exports as EMF. Here's what you'll get, versus the type we produce:

EMF from Adobe Illustrator: wonky curves!
Adobe Illustrator EMF
EMF from Brandwares
Brandwares EMF

We create robust logos with a tiny file size and razor sharpness at any resolution and transparent backgrounds and they will never get downsampled by Office or Acrobat!


Best Quality Logos In Use

Once we've placed our EMF logos in your presentation, they can be ungrouped in Windows versions of PowerPoint, then you can key part or all of it to a theme color. If your presentation contains multiple color themes, changing theme colors will change the keyed logo element automatically. This can be a slick trick for presentations with different sections in different code colors. If you're working with a Mac, let us know and we can ungroup and key the logo parts for you.

Best quality logos in identical slide layouts keyed to different color themes

The layout for these slides is identical. Each uses a different color theme that varies one code color.

Transparency is not supported in most EMF exports, but by importing and ungrouping the logo, you can add transparency back in. In PowerPoint, choose Drawing Tools>Shape Fill>More Fill Colors..., then set the Transparency slider. This works the other way around from Illustrator, but the units are the same. If the Illustrator file used 40% Opacity, set 60% Transparency in PowerPoint.

Best quality logos benefit from EMF transparency

From L to R: each character has 10% more transparency. You can't get this by adding transparency in Illustrator, you must re-create it in Office.

EMF are not a great candidate for objects like disclaimers. Each letter includes one or 2 complex curves, so a paragraph of text will be much larger that the same disclaimer rendered as an indexed-color PNG or even a JPEG of the same text. But for logos, they're pretty great. You get the same small file size and pin-sharp appearance regardless of how much you enlarge it. Applying image compression or printing to a low-res PDF leaves EMF logos in pristine condition. It's by far easiest way to create the best quality logos for Microsoft Office.

OOXML Hacking: Document Repair

You have a crucial thesis or presentation that's due in the morning, but when you try to open it, you get a message saying the file has an error. It may seem like the end of the road, but with a little XML hacking, you can repair your file in just a few minutes and be back to work. Document repair is something you can do yourself.

First, let's look at different causes of file corruption. The number one cause is working on files while they are on temporary or removable media. A USB or flash drive is a convenient way to carry data. The common alternative is to keep your information in the Cloud. But both of these are hazardous if you're editing files. Accidentally ejecting a USB stick or losing your Internet connection while a file is open in Office is a near-guarantee of corruption. This type of corruption is also disastrous, because the file contents are so thoroughly scrambled, there is no way to recover the data.

But there are also files that get scrambled by software and usually these are recoverable. We'll use the same techniques covered in previous posts. Windows users should review XML Hacking: An Introduction, while OS X hackers need to follow these instructions: XML Hacking: Editing in OS X


Is the File Recoverable?

When opened in Office, unrecoverable files may give you errors like these:

Recover Text
Parts Missing

The first step is to rename a copy of the file with a .zip ending and expand it. An unrecoverable file (one scrambled by a USB or Cloud drive) will almost always raise an Zip error. Cut your losses, you're not going to be able to fix this. As a second-best alternative, try opening the original damaged file in NotePad (on Windows) or Text Edit (OS X) to recover whatever text you can. You also might be able to extract some contents by opening in a different word processor, like Pages on a Mac.

By contrast, if you see the following messages, document repair is possible:

Illegal Character
XML Corruption Warning

You can see that the first 2 messages are generic, while the second 2 give a specific location for the error. This means the file is at least partially readable by the program.


Error-finding

There are quite a few document repair articles on the web that are worth reading for the variety of tools that people are using. I prefer a combination of a good text editor (NotePad++ on Windows, BBEdit on OS X), plus a modern browser like FireFox or Chrome. The text editor is where you do the editing, while the browser parses the XML and finds any errors.

You've already unzipped the document or presentation, now look for the XML portion that contains the error. Most of the time, with a Word file, document.xml will be the culprit. Open document.xml in the text editor and Prettify (NotePad++) or Tidy (BBEdit) it to make it readable. A raw document.xml file only has 2 lines, which is why the XML errors are invariably reported as being on line 2. Making the text readable also adds useful line numbers to error reports, making the errors much quicker to find. Now the file should look like this:

document.xml

Save document.xml, then open it in your choice of browser. This is how FireFox and Chrome show where the first error is:

Browsers View XML

As you can see, the report is a little more informative in FireFox. The error is a mismatched tag: a tag was opened but not closed. It expected to see the closing tag </mc:Fallback> and it tells you exactly where it thought that tag should be. The arrow points to the first character that is in error. The correct way to interpret this is that the expected end tag should be inserted immediately before the tag pointed to.


Document Repair Technique

Here's what the error location looks like in the text editor:

Document Repair Error Location

Then here is what it looks like after inserting the closing tag (you can copy and paste directly from the browser window):

Step 1 Document Repair

Save document.xml in the text editor, then refresh the browser. The next error is shown:

Step 1 Result

Repeat the steps. Some files have only a couple of errors, others may have dozens. You'll know when you're done, because refreshing the browser will give you a different screen, displaying the XML instead of an error message:

Final Document Repair Result


Rebuild the File

Close the text editor and browser, then re-zip the folders and [Content_Types].xml, giving the zip file a new name and a file ending that matches the original. Open it to ensure it works. Office does not tolerate XML errors well and doesn't give you clear error messages, so if the file doesn't open, you missed something. In addition, Mac users have to use Terminal to zip and view files, as noted on the XML Hacking: Editing in OS X page.

Lots of people ask "How can I prevent this?", but there isn't a really good answer. If a file can be repaired, it's almost always due to a program bug that writes malformed XML. In the Word file used for example, this is often when a placed graphic has no fallback information, which is supposed to help with graphic depiction in older file formats. It appears that the program omits the closing fallback tags when saving and you get the error. It's not your fault, but Microsoft has not been able to find and eliminate this bug since the 2007 version.

OOXML Hacking: Linked Excel Charts

Time marches on and this post is obsolete. Please check out XML Hacking: Fix Broken PowerPoint Links for more current information on this topic.

OS X versions of Microsoft Office have always been the poor step-children in the Microsoft family. Always missing important features found only in the Windows alternatives. One of these obvious disparities has been in the area of linked Excel charts. In Windows, Microsoft uses their OLE technology to allow, for instance, an Excel workbook to be linked to a PowerPoint presentation.

The Excel workbook can still be edited independently. The charts can be revised based on new data, and when the presentation is opened, the updated information will be displayed. This is a powerful tool in many situations where information is changing rapidly and the presentation must stay current. This approach also leverages the inheritance of data. This allows users to have only one data source that drives updates in many different places.

Of course, OLE being a proprietary Microsoft technology, it has almost no support on other operating systems. The only way it appears in OS X is if an individual software vendor creates an instance that works with their code. Office for Mac has had its own tiny version of OLE that allows some, but not all the features found in Windows. You could only insert Office objects (forget about PDFs) and you couldn't link, only embed.

Until now. With the release of Office 2016 for Mac, the tiniest crack of linkability has finally opened. Try these steps: Open Excel 2016 for Mac and create a chart. Select that chart and copy it. Open a presentation in PowerPoint and click on the down-pointing arrowhead beside the Paste button. Now your options include all of the following:

  • Use Destination Theme & Embed Workbook
  • Keep Source Formatting & Embed Workbook
  • Use Destination Theme & Link Data
  • Keep Source Formatting & Link Data
  • Paste as Picture

Options 1, 2 and 5 have always been available. The news is with 3 and 4, where linked data for charts becomes a new possibility. But along with this fresh opportunity comes a problem that hasn't been addressed by Microsoft. It's very nice to link charts, but the Microsoft default is always to hard code the link path. This means that moving the presentation and Excel source to a different computer destroys the links. The charts are no longer editable, because the link path has changed.

Remember the poor step-child analogy? Here it is again: Windows versions of PowerPoint allow you to edit the links in the program so you can fix the path problem. But no such facility exists on the Mac. To update those linked Excel charts, you need to ... hack the XML!

If you're new to XML hacking, please read my introduction to the subject. Since this topic is specific to OS X, it's also vital to read XML Hacking: Editing in OS X as well. I assume that you have figured out the correct path to the Excel file on the computer where the presentation has been moved.

Updating linked Excel Charts with XML Editing

After unzipping the presentation, you're going to look inside the folders for ppt/charts/rels. Office XML files are full of rels folders that contain the relationships between the components of the document. Each chart in the presentation consists of a file i.e. chart1.xml with a corresponding chart1.xml.rels inside the rels folder. The number in the chart name increments for each additional chart linked.

The contents of chart1.xml.rels looks like this:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
  <Relationship Id="rId1" Type="http://schemas.microsoft.com/office/2011/relationships/chartStyle" Target="style1.xml" />
  <Relationship Id="rId2" Type="http://schemas.microsoft.com/office/2011/relationships/chartColorStyle" Target="colors1.xml" />
  <Relationship Id="rId3" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/oleObject" Target="file://localhost/Users/server/Documents/Dockets/Test/Excel/LinkTest.xlsx" TargetMode="External" />
</Relationships>

The lines of code are long, please scroll to see where I've bolded the path and file name, this is the section you have to modify to update the linked Excel chart.

Just as a comparison, here's the analogous information from a PowerPoint 2010 file. In this case, there is not a chart folder containing chart.xml files. Instead, the charts are part of the slide files and are found in slide1.xml. The rels file is slide1.xml.rels and it looks like this:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
	<Relationship Id="rId3" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/oleObject" Target="file:///I:\Dockets\Test\Excel\ExcelLink2010.xlsx!Sheet1!%5bExcelLink2010.xlsx%5dSheet1%20Chart%201" TargetMode="External"/>
	<Relationship Id="rId2" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/slideLayout" Target="../slideLayouts/slideLayout7.xml"/>
	<Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/vmlDrawing" Target="../drawings/vmlDrawing1.vml"/>
	<Relationship Id="rId4" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/image" Target="../media/image1.emf"/>
</Relationships>

A close examination shows that much of the same information in a Mac file is also here, but the file and path is Windows-style. Using this information, you're ready to update those linked Excel charts with the best of them!
