Lost excel files

PLEASE HELP! I have lost all of my files from excel

Hi, do you mean that you have lost records/rows from your Excel file?

No I can’t open any of my files in excel since I synced them with AppSheet

What does it say when you try to open them?

I have them back sorry for the panic I don’t know what I did wrong but all of a sudden my excel files had gone

Okay good!
