Editable Lines on Layouts – Cool code

Lines or rules on a PowerPoint design are such a pain. If you place a simple line shape on a slide layout, it is static content. A slide made from that layout will show the line, but it will not be editable or deletable. So most presentation designers use sample slides that have rules added, so they can be moved or deleted. Clunky! If only there was a way to create editable lines on layouts…


Manually Adding Editable Lines on Layouts

This article came from an email I received from Jacob Liao, who sent a sample showing a rule placed on the layout that could be changed on the slide created from that layout. Here are the steps to create this effect using only the user interface in PowerPoint:

  1. On the slide layout, create a new placeholder using Slide Master>Insert Placeholder. You could use any type, but I tend to use Online Image placeholders, since those are rarely used in branded presentations. This helps ensure that other content won’t get put in this placeholder if the user switches layouts. As a convenience, make the placeholder the width (or height) of the rule that is to appear.
  2. Format the placeholder with a border matching the line or rule you want, giving it the correct color and rule width. Delete the default placeholder text and any bullet.
  3. With the placeholder still selected, choose Shape Format>Edit Shape>Change Shape and choose Callout: Line with No Border.
    Callout Line with No Border for editable lines on layouts
    The placeholder border disappears, but the callout line appears beside the shape, formatted with the shape’s border color and weight.
  4. Drag each end of the callout line to align with the edge of the placeholder. This can be a bit fiddly to get it exact.
  5. Give the placeholder a fill of No Fill and set the height (or width, for a vertical rule) to 0.
  6. Close the Slide Master view, create a new slide from the layout and test your new editable line.

Adding Horizontal Editable Lines on Layouts with VBA

You can really speed up this process by creating these rules with macros. For horizontal rules, start by adding a placeholder that is the width of the rule, with the top edge of the placeholder where the rule should be placed. With the placeholder selected, run this macro:

Sub EditableHorizontalLine()
    Dim oShape As shape

    For Each oShape In ActiveWindow.Selection.ShapeRange
        With oShape
            With .Fill
                .Visible = msoFalse
                .Transparency = 1#
            End With
            .AutoShapeType = msoShapeLineCallout2NoBorder
            .Adjustments(1) = 0
            .Adjustments(2) = 0
            .Adjustments(3) = 0
            .Adjustments(4) = 1
            .Height = 0
						.Decorative = msoTrue
        End With
    Next oShape
End Sub

Adding Editable Vertical Rules with VBA

It’s much the same for vertical rules. Create a placeholder that is the same height as the rule will be, with the left edge of the placeholder at the rule position. With the placeholder selected, run this macro:

Sub EditableVerticalLine()
    Dim oShape As shape

    For Each oShape In ActiveWindow.Selection.ShapeRange
        With oShape
            With .Fill
                .Visible = msoFalse
                .Transparency = 1#
            End With
            .AutoShapeType = msoShapeLineCallout2NoBorder
            .Adjustments(1) = 1
            .Adjustments(2) = 0
            .Adjustments(3) = 0
            .Adjustments(4) = 0
            .Width = 0
						.Decorative = msoTrue
        End With
    Next oShape
End Sub

Doug Popovich wrote about the code above, asking if there was a way to mark the shape as decorative, since it contains no text. So I added the line .Decorative – msoTrue, which does exactly that, saving you the trouble of manually marking the line in accessible decks.

Automated Word Master Documents – Cool Code

Word Master Documents are a useful feature with a problem. The master document along with its subdocuments can easily get corrupted, sometimes losing the whole collection of Word files. Word professionals will normally advise you to steer clear of them, for this reason. Here’s how to create automated Word master documents that make this feature safe to use.

When you have a collection of Word files, perhaps from disparate sources, and you need to print them or save to PDF with a common table of contents, Master Documents are a good solution.

In my opinion, the real problem is that Master Documents are work to assemble. When you’ve put all the effort in to create one, it’s so tempting to keep it as a permanent collection. But over time, some of the subdocuments need to be revised. That’s when the heartbreak begins, because editing the subdocuments while they are part of a master document can easily corrupt part or all of the collection of files.


Automated Word Master Documents

I’ve created a Word template with a VBA macro that automates the creation of a master document from a folder full of Word files. If the master document is easy to create, then it’s easy to delete when you’re done printing. And that’s exactly what you should do: use the to create temporary master documents, print or save to PDF, then put the master file in the Trash. The folder of Word files that were the source of the subdocuments will be untouched and uncorrupted.

The next time you need to print, simply run the macro again. Create a new master, print it, delete it. This is the safe way to use this powerful Word feature.

The template works with both Windows and macOS versions of Word. You can use the file as a standalone template for occasional use. Double-click on it to create a fresh Word file. Click on the Insert tab, then on the Insert Subdocuments icon at the right end of the ribbon. Choose the folder that contains your Word documents. After the subdocuments are added, add a table of contents, if you like. Print or save to PDF, then delete the automated Word master document.

You can also use the template as an Add-in. This is handy if you often create master documents. See the instructions that accompany the template to learn how to install it. Then, whenever you open Word, the Insert Subdocuments icon will appear at the right end of the Insert tab.

Add Subdocuments command

Installing as an Add-in has the advantage that you can easily use a preformatted Word file that already has a table of contents set up ahead of time. You can create, print and delete an automated Word master document in a matter of seconds.

Here’s the link to the download: Automated Word Master Documents Assembler with Instructions.

Please note: You might ignore the instructions to delete the master document after printing. You might corrupt your files. Because of this potential problem, use this add-in at your own risk. We are not responsible for document corruption or data loss in your documents.

Word for Mac Content Control Add-in

After 15 years, I got tired of waiting for Microsoft to provide Content Controls in Word for Mac. So I wrote a VBA add-in to do it. The Word for Mac Content Control Add-in is free if you subscribe to this blog. There’s no installer (Apple’s sandbox requirements for automatic installation are onerous.), but I provide installation instructions.

Content Controls are a superior way of creating forms, easier to create and use then the Legacy Form Fields that are built into Word for Mac. In a previous post, I’ve written about how you can insert content controls using VBA: Content Controls for macOS – Cool Code. But using VBA requires more technical ability than the average Word user has. So writing an add-in makes these controls available to a much wider group of users.

The new content controls appear on Word’s Developer tab:

Developer tab showing Content Controls

The Properties button opens a dialog that allows you to set the items relevant to that type of control:

The Properties dialog


Current issues with this Content Control add-in:

  • In Word for Windows, you can set a separate character style for the control. The VBA commands for sorting styles don’t do the same thing as the Word interface, so I haven’t been able to make this work the same as in Windows. Using my Content Control add-in, the content controls currently take on the style of the paragraph in which they are inserted, except for the Date Picker which displays Times New Roman (?!) when a date is selected.
  • The color for a control can be set to the same colors as in Windows, but there isn’t a custom color input yet.
  • If and when Microsoft gets around to adding content controls, the checkbox will probably select checked and unchecked characters from the macOS Emoji & Symbols dialog. Unfortunately, that dialog includes many system fonts that can’t be embedded in a file (this is a big problem with choosing bullets in PowerPoint, but that’s material for a different article). So I’ve created a subset of checked and unchecked symbols that can be used in checkboxes. These characters will work as expected and can be embedded in a template or document.
  • The properties dialog in the Content Control add-in can’t preview the checkbox characters, because there is no way for VBA to retrieve the symbols currently used by a checkbox.
  • The date picker should be able to use a world-wide variety of locales and calendar types. I haven’t been able to program the system calls to macOS to get this information yet. The date picker currently uses U.S. defaults for date formatting. Using Microsoft date formatting codes (dd-mm-yyyy, etc.), you should be able to set up dates for other languages based on a Latin (Western) script. This is one of the items that needs testing in other languages.
  • A known error occurs if you try to insert a Content Control into an old Word file in .doc format. You’ll see an error like Run-time error 445: Object doesn’t support this action. Update the file to .docx format to fix the issue.
  • A few users get error messages when trying to modify existing content controls. To date, we have not been able to reproduce, and thus solve, this bug. If you get an error, please post a comment including your processor info (Intel or Apple chip), macOS version and Office edition.

You can get a free copy of the add-in by subscribing to this blog. If you’re already a subscriber, please write to me at the email in the right-hand column, and I’ll send it to you. Please note, we do not send to disposable email addresses.

PowerPoint Icon Gallery – Cool Code

Years ago, Ken Puls of the excellent Excelguru site published an Excel add-in that displays the icons built into Excel. This reference is useful for any programmer wanting to repurpose built-in icons to use with their own code. Here’s where you can download the original: Office 2007 Icon Gallery. His version has gradually become outdated as Microsoft has added more icons to the software, and there was no version for PowerPoint. The latter isn’t such a big deal, because Excel, Word and PowerPoint share a common library of icons.

With Ken’s gracious permission, I’ve created an updated PowerPoint version of this add-in. This displays all the icons in current versions of Office, and it runs under PowerPoint for Windows and for Mac.

This is version 2. If you downloaded this prior to January 24, 2023, please download and install this improved version. I haven’t created an installer for this, but here are the instructions for manual installation:


PowerPoint Icon Gallery Installation

Download Link

Icon Gallery Add-in Download

Windows Installation

The download is a zip file that holds a single Icon Gallery.ppam file. Expand the zip and copy the .ppam file to your desktop or other easy-to-find location. Here’s how to make it appear in PowerPoint for Windows:

  1. In PowerPoint, choose File>Options>Add-ins.
  2. Change the Manage dropdown to PowerPoint Add-ins, then click on the Go button. The Add-ins dialog opens.
  3. Click on the Add New button. Navigate to the location where you saved the .ppam file, select it and click on OK. The Add-ins dialog should look like this, displaying the add-in name with a check mark beside it:
    Windows Add-in Dialog
  4. Click on the Close button.
  5. In PowerPoint, select the View tab. At the right end, you should see a new group called Office Icons:
    Office Icon group

macOS Installation

  1. In PowerPoint, choose Tools>PowerPoint Add-ins from the macOS menu bar. The Add-ins dialog opens.
  2. Click on the Plus (+) sign. Navigate to the location where you saved the .ppam file, select it and click on OK.
  3. PowerPoint will pop up a macro warning. Click on the Enable Macros button.
  4. Then PowerPoint will pop up this dialog, astoundingly badly worded, even for Microsoft:
    Turn Off Macro Virus Protection
    It sounds like you’re turning off macro protection completely, right? Well you’re not. This just turns it off for this file, and it has no effect on the macro virus protection settings, so there’s nothing to even turn on again! Click on Turn Off.
  5. The Add-ins dialog should look like this, displaying the add-in name with a check mark beside it:
    Icon Gallery Add-in
  6. Click on the OK button.
  7. In PowerPoint, select the View tab. At the right end, you should see a new group called Office Icons:
    Icon Gallery on View tab

Using the PowerPoint Icon Gallery

Windows Useage

Click on one of the galleries to see a group of icons. Here are the first 256:
Gallery 1 Icons

Hover over an icon to see its idMso command name.

Click on an icon to open a dialog that shows the command name for use with idMso or imageMso commands. Click on the Copy to Clipboard button to copy the command name. Then paste the name into your XML or other code. Due to a bug in File Explorer, all Explorer windows must be closed for this to work as expected.

macOS Useage

Click on one of the galleries to see a group of icons:
Icon Gallery - Mac
Note the grey spinning icons: Those are objects that exist in the Windows version, but not in macOS. One of the drawbacks of trying to develop for both platforms is that Microsoft has only done half the job in Office for Mac. Avoid these icons for cross-platform macros.

Hover over an icon to see its idMso command name.

Click on an icon to open a dialog that shows the command name for use with idMso or imageMso commands. Click on the Copy to Clipboard button to copy the command name. Then paste the name into your XML or other code.


Uninstalling the PowerPoint Icon Gallery

Windows Uninstall

  1. In PowerPoint, choose File>Options>Add-ins.
  2. Change the Manage dropdown to PowerPoint Add-ins, then click on Go.
  3. Select the add-in, then click on the Remove button. Close the dialog. The icon gallery disappears from the View tab.

macOS Uninstall

  1. In PowerPoint, choose Tools>PowerPoint Add-ins (on the macOS menu bar).
  2. Select the add-in, then click on the Minus sign (-). Close the dialog. The icon gallery disappears from the View tab.

Notes

Wouldn’t it make more sense to have this on the Developer tab? Well, yes, it would, that’s where the Icon Gallery appears in Ken Puls’ original add-in. But I made one file to work on both Windows and macOS. PowerPoint for macOS is missing the Developer tab. So I put this on the View tab as a second-best location.

Why no icon preview, as in Ken’s original add-in? Previewing icons in VBA relies on the CommandBars.GetImageMso command. This has been deprecated and in recent versions of Office, does not deliver an accurate icon preview. The command is not available at all on Macs, so I removed the preview. But you can see the 32 x 32 version of the icon in the gallery dropdown, not much has been lost.

Edit OOXML with VBA – Cool Code

For Office users, the closest thing to a “programming language of the people” is VBA. It’s not too hard to get started, there are gobs of help information from a good search, and the results are immediate. But VBA’s abilities haven’t expanded as its environment has changed. This has become abundantly clear with current versions of Office, where task panes and the Windows-version Backstage haven’t been included in the VBA object model. Many want to edit OOXML with VBA, but Microsoft prefers to shuffle you off to the Open XML SDK programmed with C# to do that job.

Fortunately, we’re on the case at Brandwares. We collaborated with programmer Jan Karel Pieterse to develop a PowerPoint version of his macro set that edits Excel OOXML. We’re making this freely available as a download so you can get the benefit of this.

Let me apologize to my macOS readers. I really try to provide solutions that work cross-platform, but this macro set relies on Windows system calls.

I’ll be honest, this isn’t the most elegant OOXML editing solution. The macro set unzips the OOXML to its component files, gives you the opportunity to edit the XML using VBA string manipulation, then rezips the OOXML to a usable PowerPoint file. The unzip/rezip operations are fairly slow, especially with large files. It’s not something you can use in a real-time editing situation.

One of Brandwares’s specialties is converting legacy presentations to new themes/templates. Often, there are OOXML mismatches that make reused slides retain artifacts or formatting from the old decks. We solve these issues with macro convertors that take a folder full of old decks and transform them into new presentations with new branding. This macro set is great for that.


Edit OOXML with VBA: a Peek Under the Hood

THe file contains 3 VBA modules and 1 class module. Module modConvert is the only one you need to modify. In it, Sub MainVBAOperations does the actual work of opening files, saving as a work file, calling the XML process, saving the modified file and deleting the work file. This is also where you would do any additional VBA processing. As one example, after you modify the XML of a slide master or layout, you have to reset the slide based on it to display the changes. MainVBAOperations is where you would do this.

The other Sub is ProcessXML. Here’s where you unzip the file being modified, open different XML parts for find and replace processes, followed by a rezip of all files back to a working file. The sample code in this module shows a typical revision to the idx numbers of placeholders, a common requirement of legacy presentation conversions and one that can’t be done with the PowerPoint interface.

The module modDisplay, by Shyam Pillai, provides the PowerPoint equivalent of the Application.Screenupdating command that exists in Word VBA. Useful to prevent the screen flashing and jumping as files are processed, it also helps speed code execution. modUNC by Randy Birch, assists with file management.

Jan Karel Pieterse wrote the class module clsEditOpenXML that does the heavy lifting of unzipping and rezipping the document to be modified and reading and writing the XML.

As noted in the code, You are free to use this code within your own applications, add-ins, documents etc but you are expressly forbidden from selling or otherwise distributing this source code without prior consent. This includes both posting free demo projects made from this code as well as reproducing the code in text or html format.


Converting Legacy Presentations

We use often use this macro set to update old (legacy) presentations with a new design. Successful updating requires meeting 5 criteria, please read this article for more details: Legacy Slides – Best Practices. As noted on that page, the 5th requirement is that placeholder idx numbers in the OOXML must match on the old and new layouts. There’s nothing in PowerPoint’s interface that allows you to set idx number, but this macro set allows you to do just that. The pre- and post-processing sections of the macros allow you to set the the other 4 parameters for each slide layout. Click here to download it.

The following advice is particular to presentation conversion. It’s routine that slide masters and layouts will be changed in that process. Then, to apply those changes to the actual slides in a presentation, the slides must be reset, as if you pressed the Home>Reset button in a presentation. Resetting slides wipes out character-based formatting. If a user has applied bold or italic or an underline to particular text, that all will disappear. It’s important to notify your client of this. To make an exact update would require a painstaking construction of a multi-dimensional array for each placeholder on each slide that would record all character-based formatting, then restore it after the update, for which you would have to charge many times as much as for the basic conversion work.

Brandwares is a world leader in presentation updating and conversion. We’re available for presentation assessments, to identify potential problems. We have multiple techniques for seamless re-use of legacy presentations. Contact us when you’re redesigning to ensure your new template will reuse your old slides without a hiccup.

Office Automation with AppleScript Reference – Cool Code

For Office for Mac users, AppleScript remains a useful tool in scripting Office documents. VBA for Mac has poor links to the operating suystem. In Windows, a programmer can easily make system calls to the OS. In macOS, the analogous system calls are not documented by either Apple or Microsoft. A few intrepid programmers have posted about macOS equivalents, but the information is sporadic and very hard to find. macOS’s built-in AppleScript can solve many of these issues, so I’m posting the best available Office AppleScript Reference.

This is old Microsoft documentation from 2008 that they’ve removed from their site. I don’t guarantee this, or offer support, I’m just posting it to make it available to interested programmers.

Office AppleScript Reference: MacScript vs AppleScriptTask

Ron de Bruin is a European programmer and MVP (Microsoft Valued Professional) who has written lots of good information about programming Office on a Mac. While he writes mostly about Excel, VBA is so similar across Office that most of the information also applies to Word and PowerPoint. Here’s his page on using the AppleScriptTask command in Office 2016 and later to call AppleScripts from a VBA macro: AppleScriptTask in Mac Office 2016 or higher.

Office AppleScript Reference: Conditional Compilation

To create a macro that can run on different versions of Office for Mac, or on both Windows and Mac, you’ll need to use conditional compilation. This uses #If – #Else – #End if statements to run a set of commands only in certain conditions. Here is Microsoft’s page on conditional statements for different Mac versions: Differentiate between Office for Mac versions at compile time. This MS reference page shows all available conditional compiler constants: Compiler constants.

Click here to download: Office AppleScript Reference.

Another useful reference for AppleScript automation of Office is the online article Moving from Microsoft Office VBA to AppleScript by Paul Berkowitz. This is a full-length book with comparisons between VBA and AppleScript, plus many real-world example scripts. It was originally published in 2007, in anticipation of Office 2008. Unfortunately, the downloadable PDF they promise is no longer available.

OOXML Hacking: Protected Area Exceptions in Word

Microsoft doesn’t have a catchy name for this feature, but I’ll try to describe it. In Word for Windows, you can select document text, then apply Read-only protection, but with Exceptions. By default, the exception is Everyone. If we untangle the word logic, this means that the document becomes read-only except that everyone can edit the selected text. It’s a far better solution than the old protection for forms.

When this type of protection is applied, the selected areas become shaded in light yellow as a visual cue that the highlighted text remains editable. Users of Word 2016 for Mac and 2019 for Mac (including Microsoft 365 subscribers) can use these documents, but can’t produce them. At least, until now.

Light yellow areas indicate editable text
Protected area exceptions in Word

Word pros will look at the square bracket and think it’s a bookmark. It’s not. Microsoft reused the bookmark character to show a Permission Range. To add these editable ranges on a Mac, we’re going to create one manually.

To start, apply Read-only protection to the document. Use Tools>Protect Document, then check Protect document for. Click on Read only, then on OK. Save the file.

Now open the file in your XML editor. OOXML Tools in the Chrome browser is fine for this job. Open document.xml inside the word folder.

Just before the text that you want to be editable, insert a line like this:

<w:permStart w:id="883447734" w:edGrp="everyone"/>

At the end of the editable text, insert this XML:

<w:permEnd w:id="883447734"/>

The beginning and end tag must have the same 9-digit random number. Each pair of tags in a document must have a different random number.

Here is a whole paragraph marked as editable:

<w:permStart w:id="783447734" w:edGrp="everyone"/>
<w:p w14:paraId="5B68C6A9">
  <w:r>
    <w:t>To make your document look professionally produced, Word provides header, footer, cover page, and text box designs that complement each other.</w:t>
  </w:r>
</w:p>
<w:permEnd w:id="783447734"/>

Here, just one word is editable:

professionally produced, <w:permStart w:id="983447734" w:edGrp="everyone"/>Word<w:permEnd w:id="983447734"/> provides header,

It’s that simple. Save the file and distribute to users.

For any of our tips that seem too complicated, Brandwares is available to do it for you. We teach the pros!


Fix It with VBA

Instead of hand-editing the XML, then applying Read-only protection, you can use a bit of VBA to solve this problem. Select the text that should remain editable, then run this macro:

Sub CreatePAE()
  Selection.Editors.Add wdEditorEveryone   ActiveDocument.Protect Password:="", NoReset:=False, Type:=wdAllowOnlyReading, UseIRM:=False, EnforceStyleLock:=False End Sub

If you have multiple areas that should remain editable, run the macro, then unprotect the document (Tools>Protect Document>Uncheck Protect document for option), select new text, then re-run the macro. Leave the document protected before distributing it.

Every AutoShape – Cool Code

There are more AutoShapes in Office than appear in the user interface. Over time, Microsoft has quietly added to the collection stored in Office. Many of the more recent shapes are used in SmartArt files, while others have no current use that I can detect. But for anyone who hacks XML or codes VBA will find this week’s download or every autoshape a useful reference.

These are all the shapes that can be used in a piece of SmartArt. This is a deep topic: SmartArt XML is a programming language with a Frankenstein syntax. But the starting point for any language is to get the names right. SmartArt and VBA both reference the AutoShapes collection in Office, but they use different names for the same objects. Many of the same shapes are seen in the Shapes dropdown of Office programs, but those names are also different. The main source of the VBA names are from this page: MsoAutoShapeType enumeration (Office), while the XML names come from this out-of-date listing: SmartArt AutoShapes.

So, for my own sanity, I created a Word document showing an example of each shape, along with it’s name in XML, in VBA and in the user interface. This has smoothed out my workflow, and it may help you as well.

Listing of every AutoShape

For any non-interface shapes, you can insert them into a document with code analogous to this. For PowerPoint:

Sub MakeShape()
  ActivePresentation.Slides(1).Shapes.AddShape msoShapeTrapezoid, 24, 24, 144, 144
End Sub

Change the bolded word to the shape name in the VBA MsoShapeType Name column.

Some shapes have specialized VBA commands, like callouts:

Sub MakeShape()
  ActivePresentation.Slides(1).Shapes.AddCallout msoCalloutTwo, 24, 24, 144, 144
End Sub

Callouts led me to a discovery about legacy versions. msoCalloutOne gives exactly the same result as msoCalloutTwo in current versions of Office.That seemed odd, so I ran the same macro in PowerPoint 2003 (I still have it installed for its macro recorder). In that version, msoCalloutOne creates a callout with a vertical leading line that can be moved up and down, but not at an angle. Presumably, MS found that useless and deprecated it.

Download the Word document showing every autoshape here.

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 length of the shortest side of the shape. Since we want to keep the radius the same size, we need to create a formula that makes a smaller number as the shorter side increases. We need an inverse number! We can create this by dividing the preferred corner radius by the short side size. And you thought you’d never need that high school math!

Here’s VBA code that will work in Excel, Word and PowerPoint on selected round-cornered boxes. Thanks to the Rembrandt Kuipers and Ernst Mathys who have commented below, this macro has been improved since it was originally published. Replace the number after sngRadius with your desired radius size in points.

Sub RoundedCornersFixedRadius()
    Dim oShape As Shape
    Dim sngRadius As Single
    sngRadius = 8.50394 'Radius size in points. 8.50394pt is equal to 3mm.

    For Each oShape In ActiveWindow.Selection.ShapeRange
        With oShape
            If .AutoShapeType = msoShapeRoundedRectangle Then
                LengthOfShortSide = IIf(.Width > .Height, .Height, .Width)
                .Adjustments(1) = sngRadius / LengthOfShortSide
            End If
        End With
    Next oShape
End Sub

To set rounded corners on a PowerPoint placeholder, open Slide Master view, select the placeholder and run the above macro.


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, sngRadius As Single
    sngRadius = 8.50394 'Radius size in points.

    For Each oWorksheet In ActiveWorkbook.Worksheets
        For Each oShape In oWorksheet.Shapes
            With oShape
                If .AutoShapeType = msoShapeRoundedRectangle Then
                    LengthOfShortSide = IIf(.Width > .Height, .Height, .Width)
                    .Adjustments(1) = sngRadius / LengthOfShortSide
                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, sngRadius As Single
    sngRadius = 8.50394 'Radius size in points.

    For Each oSlide In ActivePresentation.Slides
        For Each oShape In oSlide.Shapes
            With oShape
                If .AutoShapeType = msoShapeRoundedRectangle Then
                    LengthOfShortSide = IIf(.Width > .Height, .Height, .Width)
                    .Adjustments(1) = sngRadius / LengthOfShortSide
                End If
            End With
        Next oShape
    Next oSlide
End Sub

And finally, for Word

Sub RoundAllWDCorners()
    Dim oShape As Shape, sngRadius As Single
    sngRadius = 8.50394 'Radius size in points.

    For Each oShape In ActiveDocument.Shapes
        With oShape
            If .AutoShapeType = msoShapeRoundedRectangle Then
                LengthOfShortSide = IIf(.Width > .Height, .Height, .Width)
                .Adjustments(1) = sngRadius / LengthOfShortSide
            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.

To use these macros with other shapes, please see my article Every AutoShape – Cool Code for a downloadable reference file showing all AutoShapes along with their XML and VBA names. Then replace msoShapeRoundedRectangle with the mso shape name you need.
