I was able to export my reports to Excel just fine three days ago. I went in yesterday to export a report to Excel and all the options for Excel were greyed out. I didn't make any updates to my computer in that time frame. When I spoke with the Intuit help desk I was told that I would have to upgrade my Quickbooks to 2022 in order to get any assistance. 

I think they may be pushing this issue through the program in order to force people to upgrade their software. I have 2021, so it's not an old version. I will be looking at other software if I can't find a fix in the next week. I am a small business that uses QB a few times a month because my business is not an accounting business. It's not worth the $350/year cost to me when I use it 2 times a month.
