Lost several day's worth of work in an Excel file?

Anonymous

I opened, edited and saved a file in Excel several times last week without issue. This included adding a new sheet, then editing it over several days.

The file is in my work account's OneDrive.

Today I opened that same file to find that all my recent work (the whole sheet) has vanished; it seems to now be a version from 2 months ago, according to the last saved date. So naturally there is nothing in version history, and I cannot find any way to check for unsaved recent changes, but in any case, it was saved and opened again several times last week without issue, so I wouldn't expect unsaved recent changes to contain anything except perhaps the most recent edit.

How is this even possible!! Is there any way to recover the many hours of work I have lost?

My device is Windows 11, I have a personal account and a work account on the machine (and I have checked; it wasn't saved in my personal OneDrive).

    Happened to me today, the file was saved on the computer. I tried looking for it by recovering unsaved versions, or show any hidden files - nothing. The whole day of work just disappeared. Usually Excel is always asking whether I want to save changes, but I dont think it did the last time.

    This happened to my girlfriend today, and I scoured the internet looking for ways to restore the file she had been working on for two days. Here is what finally worked.

    Open the folder where your excel file disappeared from. In Windows Explorer, enable "view hidden items".

    Is there a .tmp file with a weird name in the same location where the file disappeared? If so:

    1. open Excel, go to "File"
    2. navigate to the folder where the .tmp file is. The .tmp file will not show up in the window.
    3. Change the file filter to "All files" (instead of "All Excel files") in the drop-down list on the bottom right corner of the file dialog. Now, the .tmp file should show up. Select it, and click "Open".
    4. Excel will throw all sorts of warnings at you, but ignore them and move forward. After a few heart-stopping seconds and progress bars, if you are lucky, your file will be rescued with all data intact.

    Best of luck.

    Hi, my spreadsheet WAS SAVED to OneDrive. I had auto save and everything on it. I am that age where you had to save everything when you were little otherwise you’d lose it. It’s deeply ingrained within me. We would have a thunderstorm and the power would go out and you would lose everything, so now I save it all. So I don’t know what happened. And they aren’t providing answers

    Yes. I had emailed my boss a copy of it, so that was the only way. Other than that, i had to redo my whole entire work log.
