A family of Microsoft word processing software products for creating web, email, and print documents.
Hi Heather Pretty,
Thanks for posting back.
I have tested it in the same Word version, and it works well for me. In this case, I suggest you try the following steps to troubleshoot whether the issue is caused by a specific location or Excel workbook.
- I suggest you move the downloaded Excel file to another local location and then use the Mail Merge feature in Word to select the Excel file as the data source. Check if the error message occurs.
- I suggest you open the local Excel file, right-click the sheet tab to copy the sheet to a new workbook, repeat the same steps to copy all sheets to the new workbook, save the new workbook, and then use the newly created workbook as the data source. Check if the issue is caused by the original workbook.
If the issue still occurs in the above situations, I think there is wrong with the Word app. Since the safe mode and repair didn't work, I suggest you try the following suggestions to troubleshoot.
1. I suggest you switch to another Windows user profile (if you don’t have another Windows user profile, please try the steps in the "Switch user" section and sign into another account, such as your personal account), run Word, and test again. This can help us to troubleshoot whether the issue is caused by the local environment in your original Windows user profile.
2. I recommend that you use the uninstall support tool to completely uninstall Office and remove its cache files, then reinstall Office from the Office Portal (www.office.com) and check again.
We look forward to your response. Thanks for your cooperation.
Sincerely,
