So, I've identified the cause of the problem. I have a very large file that crashes semi-regularly, and every time it crashes Excel asks if I'd like to attempt to recover. If I can remember having saved recently, I just say no, it closes the file and the program, and I open and continue... no problems.

If I can't remember when I saved last, I let it recover and save as a new copy of the file. When this happens, both the original file AND the new recovery file have cell formatting changed to dates. It seems like every cell that isn't already specifically formatted to something else is converted to date format. Cells that I have already specifically formatted to accounting, or percent, are skipped over. Everything else, including general formats, are changed to date, and date becomes the default cell formatting for new sheets created in the workbook.

This is an extreme pain, as the spreadsheet has enormous quantities of data I will need to review and reformat, not to mention drill downs of pivot tables now default as date format, as do pivot tables in general that are created in new sheets. Does anyone have any ideas or suggestions? The shocker is that it corrupts the original file during the recovery process.

Whats the difference between CONCAT and CONCATENATE?
The newer CONCAT function can reference a range of cells. =CONCATENATE(A1,A2,A3,A4,A5) becomes =CONCAT(A1:A5)
