Hi, I have a file that I use regularly. Suddenly, today, I am getting an error message that I cannot access the file. "Alert Excel cannot open the file '(~$file name.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."
Is there anything I can do to recover this file? Also, is there something wrong with my computer like a virus or something that may have caused this problem that I should address?
Thank you very much for any help.
