Hi @Chaise Belt
Could you please tell us what version of Office are you using?
I suggest you create a simple Excel files to test the Word mail merge.
If the issue is reproduced, please try following steps:
- Update Office to the latest one.
- Please try to remove cache files like below
Close Word, open Finder.
Press Command + Shift + G, input “~/Library/Containers”, remove com.microsoft.word (If your Mac OS is Big Sur, the cache folder named Microsoft Word.) to desktop.
Open word, and check if it works correctly.
If the issue is not reproduced, I would suggest you check your Excel file asgin, such as use of quotation marks and fonts.
You can also copy all data to a new Excel file to check this issue.
