I did some house cleaning on my ID Safe today and wanted to export a new file when I was done.
I exported the file and when I tried to open it I got "Excel cannot open the file ***.xlsx because the file format or the file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file". I have done it several times with the same result.
Admittedly I have not done this for a year now but I had no problem when I did it last and last years files works fine.
Did I just have a brain fart here, what I am missing.
Thanks for the time,
Mike
