Just today I am not able to export an application to EXCEL. Is there a bug?

I have always been able to export to EXCEL CSV so I can put my leads into Salesforce.  Now today it is not working.

It's working for me here. What build number of Office do you have installed?
I'd recommend running a repair of Microsoft Office: https://support.office.com/en-us/article/repair-an-office-application-7821d4b6-7c1d-4205-aa0e-a6b40c...
