- Device & OS
- not provided
- Scenario
- Updating a shared formatting style, such as hiding or revealing text for a particular style class, across a large batch of Word documents.
- Observed behavior
- Updating the document styles manually is too time-consuming, prompting the need for a VBA macro or template-based batch processing tool to toggle font properties automatically.
Before running any batch macro, consolidate all your target Word documents into a single dedicated folder and create a secure backup copy to prevent accidental data loss during the automated process.
Use a VBA Macro to Batch Update Styles in a Folder
Run a VBA script that loops through all Word documents in a specific directory, updates the target style's font properties, and saves the changes automatically.
This method is highly efficient when dealing with hundreds of standalone documents. The macro will open each file, locate the specific style, modify the hidden font property, and then save and close the file.
Open Microsoft Word and press ALT + F11 to launch the Visual Basic for Applications (VBA) Editor.
Click on 'Insert' in the top menu and select 'Module' to create a blank workspace for your code.
Write a script utilizing the Dir() function to iterate through all .docx files within your target folder path.
Inside the loop, insert the command ActiveDocument.Styles("CMT").Font.Hidden = True (or False) to toggle the font visibility for that specific style.
Add commands to ActiveDocument.Save and ActiveDocument.Close within the loop, then press F5 to run the macro across the entire folder.
Update Styles via a Shared Document Template
If all your documents are linked to a single shared template (.dotm), you can update the style in the base template and force the documents to inherit the change.

Frequently Asked Questions
How do I change the macro to target a different Word style?
In your VBA code, locate the line reading ActiveDocument.Styles("CMT") and replace "CMT" with the exact name of your target style, such as "Heading 1" or "Normal".
What should I do if the Developer tab is missing?
To enable the Developer tab, go to File > Options > Customize Ribbon. In the list of Main Tabs on the right, check the box next to Developer and click OK.
Will this VBA macro work on older .doc files?
Yes, the macro can process legacy .doc files. You just need to ensure your Dir() function is configured to find both extensions, for example by using Dir(strFolder & "*.doc*").
Why aren't my documents updating from the shared template?
Make sure that 'Automatically update document styles' is checked in the Document Templates dialog. Also verify that the files are still correctly mapped to the updated .dotm template path.
