Hi,
Thanks for your response.
Let's open a new Excel sheet, click File > open and navigate to the location where the issue causing documents are located, select them and click OK and check how it works.
If issue persist, let us repair Office from the Control Panel and check.
Hope it helps. Try the suggestions and let us know the result at your earliest convenience.
Thank you.
