A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
It only happens occasionally. I haven't discerned a pattern.
I don't get an error message.
Unfortunately, I couldn't test the Format > Autofit Column Width functionality because I haven't been able to recreate the issue. I checked a lot of files, but I had already manually expanded the columns. I'll try Format > Autofit Column Width the next time I encounter this problem.
