Since my recent Microsoft update, I can no longer open my excel files. Not good. I can't find any way to recover from anywhere including temporary files. Can anyone help please?
Try using LibreOffice and/or iWork Numbers, pending Microsoft sorting out this.
You need to direct your question to Microsoft or look at their support site, since their product isn't working after their update.
Thank you!
As a follow to my initial message. Here is the Alert that I get when trying to open:
Excel cannot open the file '~$SL 2020 BOOKINGS.xlsx' because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file.
Recent MS update has made excel files unusable
