I moved them to a folder on the desktop of my Mac laptop.
Yes they are now on my desktop but when I click on them I get this message "We're sorry, a server error occurred. Please wait a bit and try reloading your spreadsheet." I then tried to move them back onto my Google drive but when I try to open the spreadsheets I get this message, "No preview available." I fear that the originals were deleted permanently and all I have are the links.
However, when I moved them to my desktop from my drive Google automatically removed them from the drive to the trash so I assumed it was safe to permanently delete them.
