Question details
The user needs to fix an issue where exporting a Word mail merge document to PDF results in distorted formatting, specifically affecting bullets and tab spacing.
- Product
- Microsoft Word 2013, Adobe Acrobat Pro DC
- Device & OS
- not provided
- Scenario
- Creating PDF files from a Microsoft Word mail merge document after an Adobe Acrobat Pro DC update.
- Observed behavior
- Standard PDF exports retain correct formatting, but running a mail merge to PDF causes the layout to break, producing incorrect bullet and tab spacing.
Before modifying your document's layout, ensure that both your word processor and PDF conversion add-ins are updated to their latest versions, and toggle on hidden formatting symbols to see how your document is currently structured.
Use Explicit Tab Stops Instead of Paragraph Indentation
Replacing automatic paragraph indents and default tab spacing with explicitly defined tab stops prevents the PDF converter from misinterpreting layout rules during the merge process.
PDF converters sometimes struggle to translate automatic paragraph formatting when rendering dynamic mail merge fields. By setting hard tab stops on the ruler, you lock the text alignment into place.
Navigate to the 'Home' tab and click the paragraph mark icon (¶) to display hidden formatting symbols. Locate and delete any unnecessary or duplicate tab arrows inserted between words or bullets.
Go to the 'View' tab on the top ribbon and check the box next to 'Ruler' to display the horizontal and vertical rulers.
Highlight the text that is experiencing formatting issues. Click directly on the horizontal ruler at your desired measurement marks to insert explicit left, center, or right tab stops.
For bulleted lists, right-click the list and select 'Adjust List Indents'. Define exact numerical values for bullet position and text indent instead of relying on default tab characters.
Proceed with your mail merge to PDF process using the Adobe Acrobat add-in to verify that the explicit tab stops have stabilized the formatting.
Isolate the Issue with a New Document or User Profile
Determine if the formatting glitch is caused by a corrupted document or user profile settings.

Frequently Asked Questions
Why does my formatting change when converting a Word mail merge to PDF?
Formatting changes usually occur because third-party PDF converters interpret automatic spacing, paragraph indentations, and default tabs differently than the word processor does. Locking in alignment with explicit tab stops bypasses this interpretation.
Can an Adobe Acrobat update cause Word add-in issues?
Yes, updates to Adobe Acrobat Pro DC can sometimes alter the PDFMaker add-in settings within Word. This can temporarily introduce bugs that alter how complex layouts, like mail merges, are rendered into PDF files.
How do I check my document for hidden tab characters?
In your word processor's 'Home' tab, click the paragraph mark icon (¶) located in the Paragraph group. This will make all hidden formatting symbols visible, allowing you to easily spot and delete extra tab arrows.
