Possible to recover excel file if it's accidentally saved over on another computer?

Go to the cache folder and there might be a cached version. This is a simple and effective way to recover overwritten excel file! If this does not help, then try to recover the overwrite excel file with data recovery software.

Here is one good tutorial for that: https://www.readdwrite.com/recover-permanently-deleted-files

P.S. Don't open the same file on two separate devices to avoid such overwriting issue in future!

The solution that worked with me:

go to this folder: C:\Users\YOUR USER NAME HERE\AppData\Local\Microsoft\Windows\INetCache\Content.MSO

You will find many office documents with names as numbers and letters, try to open them all of choose the file with the largest size or the one with the date you remember.

I hope this helps you as it did with me.

I wrote a detailed explanation, but kept getting this error message. So I will only say that I prompted - editor won't let me name Ai source - for a macro and I was able to fix 1,723 links in less than a minute.

I understand your situation and how frustrating it must be to lose that much work. Recovering the accidentally overwritten Excel file might be possible, but the chances depend on which methods you can try:

Built-in options:

1. Previous Versions:

   • If you're using Windows with File History enabled, right-click the overwritten file and go to "Properties" > "Previous Versions". If available, you can restore an older version from before you saved on computer two.
   • Check if OneDrive or your cloud storage has version history enabled. Some services like Google Drive and Dropbox offer similar features.

2. AutoRecover in Excel:

   • Open Excel and go to "File" > "Info" > "Manage Workbook". Click "Recover Unsaved Workbooks" and see if your new work was automatically stored there.

Data Recovery Software:

• If the methods above don't work, you can try data recovery software. However, there's no guarantee they'll succeed, and they can be costly.

Other considerations:

• Did you have any temporary files stored locally on either computer after working on the new page? They might contain fragments of your work.
• Was the file stored on a local server or network drive? If so, there might be backup versions available depending on the system's configuration.

Prevention for future:

• Always save your work with unique names or timestamps while working on different computers.
• Consider enabling version history for your cloud storage.
• Utilize cloud platforms that offer real-time collaboration features to avoid conflicts.

Unfortunately, there's no single definitive answer to recovering your lost work. It depends on the specific circumstances and available options. But hopefully, exploring these avenues might offer a chance to retrieve at least some part of your efforts.
