A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Hi, thanks for posting here in Microsoft community, at this point, the file might not have been saved properly or could be permanently deleted.
You can try Excel AutoRecover, simply open Excel then File then Info then Manage Workbook then Recover Unsaved Workbooks.
Then search for .asd or .wbk files, these are auto-save or backup files Excel sometimes creates.
Also, check Backup Services, if you have Windows File History or another backup solution enabled, restore from there.
Also, do you recall if the file was ever saved to a specific folder or location before it disappeared? This will help narrow down whether we’re dealing with an unsaved file or a deleted one.
I hope this helps you out, let me know how it goes.
