Recovering an unsaved Excel file can feel like a race against time. Whether it’s a report you’ve been working on for hours or important data entered just moments ago, losing your work unexpectedly can be stressful. Fortunately, Microsoft Excel offers several built-in features and tools to help you recover unsaved files.
Unexpected Power Failure: A sudden power cut can cause Excel to close without saving.
Program Crash: Excel or the computer crashing can interrupt the saving process.
Closing Without Saving: Accidentally clicking “Don’t Save” when prompted.
System or Software Updates: Automatic restarts during updates may close Excel abruptly.
User Forgetfulness: Simply forgetting to save periodically while working.
Knowing these can help you apply recovery strategies quickly and prevent future data loss.
Preparation: Enabling Excel’s AutoSave and AutoRecover Features
Excel has two critical features to minimize loss of unsaved work: AutoSave and AutoRecover.
AutoSave is available for files stored on OneDrive, SharePoint, or Microsoft 365 cloud accounts. It automatically saves your work every few seconds.
AutoRecover saves versions of your file locally at set intervals if you’re working on a file saved on your computer.
To maximize your recovery options, you should enable and configure these:
Open Excel.
Click File > Options > Save.
Ensure the box for “Save AutoRecover information every X minutes” is checked. The default is 10 minutes; reduce it to 1 or 2 minutes for more frequent backups.
Check “Keep the last AutoRecovered version if I close without saving.”
If you use OneDrive or SharePoint, turn on AutoSave at the top of the Excel window when working on files saved there.
Having these enabled will significantly increase your chances of recovering unsaved work.
Method 1: Recover Unsaved Excel File Using Excel’s Built-in Recovery Feature
Excel automatically saves temporary backup copies of files you’re working on, even if you didn’t explicitly save the file. Here's how to access those:
Open Excel.
Go to File > Info.
Look for a section labeled Manage Workbook or Manage Versions.
Click on Recover Unsaved Workbooks.
A dialog box will open showing all unsaved files Excel has temporarily saved.
Look for your file by date and time.
Select the file and click Open.
Save the recovered file immediately using File > Save As.
This method is often the fastest way to recover a recent unsaved Excel file.
Method 2: Search for AutoRecover Files Manually
If the built-in option does not show your file, you can search manually for AutoRecover files stored on your computer. These files have the extension .asd or .xlsb.
Steps:
Open Excel.
Go to File > Options > Save to see the path for AutoRecover files under AutoRecover file location.
Open File Explorer and navigate to this folder.
Look for files with the prefix “AutoRecover” or files ending with .asd, .xlsb, or .xar.
Double-click these files to open them in Excel.
If you find your data, immediately save it properly with File > Save As.
If the AutoRecover path is unclear or empty, check the default locations below depending on your Windows version:
Windows 10/11: C:\Users\[YourUserName]\AppData\Local\Microsoft\Office\UnsavedFiles
Alternatively: C:\Users\[YourUserName]\AppData\Roaming\Microsoft\Excel\
To access these folders, you may need to enable viewing hidden files and folders:
Open File Explorer.
Click View tab.
Check Hidden items.
Method 3: Use the Document Recovery Pane
If Excel crashes unexpectedly, the next time you open Excel, it may display the Document Recovery pane on the left side.
Look for your file(s) listed there.
Click on any recovered version to open it.
Review the contents, then save the file immediately.
If the Document Recovery pane doesn’t appear, try restarting Excel or your computer, as sometimes it shows after a reboot.
Method 4: Recover from Temporary Files
Sometimes Excel creates temporary files during your session. These can sometimes be recovered even if Excel didn’t save them properly.
Open File Explorer.
Navigate to the following directory, replacing [YourUserName] with your Windows username:
mathematica
CopyEdit
C:\Users\[YourUserName]\AppData\Local\Temp
Look for files that begin with ~ or have the extension .tmp.
You can sort by date modified to find recent files.
Try opening these files with Excel.
If the file opens and contains your data, save it immediately as an Excel file.
Temporary files can be hit or miss, but it’s worth checking this folder if other methods fail.
Method 5: Check the Recycle Bin
If you accidentally deleted the Excel file rather than it being unsaved, it might be in the Recycle Bin.
Open the Recycle Bin on your desktop.
Search for the Excel file by name or by recent modification date.
Right-click and select Restore if found.
The file will be restored to its original location.
This method is effective if you mistakenly deleted a saved Excel file instead of losing an unsaved one.
Method 6: Use Previous Versions Feature (Windows)
Windows sometimes keeps backup versions of files via File History or System Restore if enabled.
To check for previous versions:
Navigate to the folder where your Excel file was last saved or supposed to be saved.
Right-click the folder and select Properties.
Go to the Previous Versions tab.
Look for older versions of the file or folder.
Select a version dated before the file was lost and click Restore or Open to copy the file to a new location.
This can be a lifesaver for files that were saved previously but overwritten or deleted.
Method 7: Recover from OneDrive or SharePoint Versions (Cloud Backup)
If you saved your Excel file to OneDrive, SharePoint, or Microsoft 365 cloud services, these platforms keep version history which allows you to recover previous or unsaved versions.
Steps for OneDrive:
Log in to your OneDrive account via a browser.
Navigate to the folder containing your Excel file.
Right-click on the file and select Version History.
Browse through previous versions and open the desired one.
Download or restore that version.
For SharePoint or Teams, the process is similar through the document library.
Method 8: Use Excel AutoSave (Microsoft 365 Subscribers)
If you are working on Excel files saved in OneDrive or SharePoint and have Microsoft 365 subscription, AutoSave keeps saving your progress live.
To enable AutoSave:
Ensure your file is saved to OneDrive or SharePoint.
Turn on the AutoSave toggle in the Excel ribbon (top left).
If AutoSave was on, you can:
Check version history online as explained above.
Open the file, and Excel will often recover recent versions automatically.
Method 9: Using Data Recovery Software for Excel Files
Panda Data Recovery
Panda Data Recovery is a reliable and user-friendly software tool designed to help users recover lost or unsaved files, including Excel documents, with ease. When it comes to recovering unsaved files, Panda Data Recovery stands out by offering effective recovery options that can restore your valuable data even if it wasn’t saved properly before a system crash, accidental closure, or power failure.
One of the key strengths of Panda Data Recovery is its ability to scan your computer or storage device deeply and locate temporary files, AutoRecover files, and other hidden data remnants that standard methods might miss. This makes it especially useful when Excel’s built-in recovery features aren’t able to find the unsaved file you need.
Using Panda Data Recovery is straightforward. After installing the software, you select the drive or folder where your unsaved or lost file was last located. The software then performs a thorough scan to detect recoverable files. Once the scan is complete, you can preview the recoverable files, including unsaved Excel spreadsheets, and restore the ones you need.
Method 10: Check Excel’s Backup Files (.xlk)
Excel offers an option to always create a backup copy when saving a workbook. This creates a file with the extension .xlk.
To check for this backup:
In the folder where your workbook was saved, look for files ending with .xlk.
If found, open them with Excel.
Review the contents and save under a new name.
To enable this feature for future files:
Open Excel file.
Click File > Save As.
Click Tools > General Options in the Save As dialog.
Check Always create backup.
Save the file.
