Excel Contents Overwritten By Another File/OneDrive Saving Multiple Iterations Incongruent with PC Copy

I don't know how I did this, but somehow I've saved my 2026 Database with an entirely different spreadsheet's contents and I can't find the contents that are supposed to be within the 2026 Database. Is there a way to go back into the history of that file/spreadsheet and reset it to a former time? Possibly restoring the correct data? To be sure, I've gotten myself in a pickle by saving both to my pc and to OneDrive - whereas One Drive saves each upload as a separate file instead of writing over the existing file as intended which is incongruent with copy saved to PC. How can I rectify so that pc copy and OneDrive copy are the same, accessible off- and on-line? The purpose of saving also to pc is inconsistent wifi. So, three issues. Can anyone offer me some wisdom? I am most grateful.

    Dear @Metts518c,

    Thank you for reaching out to the Microsoft 365 Q&A forum. We understand how critical your 2026 Database is and how stressful it can be when data appears overwritten. This issue where OneDrive creates multiple iterations instead of a single file is usually caused by a "Sync Conflict" between your offline PC edits and the cloud version. 

    To help me narrow down the cause, could you please provide the following details?  

    1. Are you able to locate any previous versions in OneDrive's version history? 
    2. How frequently do you experience issues with saving changes in Excel? Is it a consistent issue or intermittent? 
    3. Have you checked your OneDrive sync settings to ensure there's no conflict? 
    4. Is there any specific error message that appears when trying to save or access the files? 

    In the meantime, please try the following official troubleshooting options which usually resolve issues with basic issues:  

    Option 1: Restore your data 

    Since the file is synced with OneDrive, you can "roll back" the file to a time before the overwrite occurred. 

    Version History (Most Effective): 

    It's simple to access OneDrive from any web browser. Just sign in with your Microsoft 365 account. 

    1. Go to microsoft365.com and sign in.
    2. In the app launcher, select OneDrive.
    3. Locate your 2026 Database file, right-click it, and select Version history. 
    4. A list of timestamps will appear. Click the three dots (...) next to a version from before the error and select Restore. 

    Check Local Backups: If the version history doesn't show what you need, check your Windows Recycle Bin or any local "AutoRecover" folders, as Excel may have saved a temporary copy during the crash. 

    Option 2: Rectifying syncing (PC vs. OneDrive) 

    To ensure your PC and OneDrive copies are always identical and accessible offline, follow these steps: 

    1. Use "Always Keep on This Device": Open your OneDrive folder on your PC, right-click your database file, and select "Always keep on this device." This ensures the file is physically on your hard drive for inconsistent Wi-Fi but will automatically sync to the cloud the moment you are back online. 
    2. Fix Duplicate File Creation:  
      • Right-click the Blue Cloud icon in your taskbar > Settings > Advanced Settings.  
      • Ensure that File Collaboration is turned on. This allows Excel to "merge" changes rather than creating a separate file when you save while offline. 

    Option 3: Maintenance and prevention 

    • Ensure your Office 365 is up to date (File > Account > Update Options), as outdated versions can struggle with modern sync protocols. 
    • Avoid "Manual" Double Saving: You no longer need to save once to the PC and once to OneDrive. Simply save into the OneDrive folder once. The system is designed to handle the "local-to-cloud" transition automatically.

That said, I truly hope these suggestions help you move forward.  

    Please let me know if you have any further questions or if the problem persists after trying these solutions. Thank you for your patience and cooperation.

    To address the issue of your 2026 Database being overwritten with another spreadsheet's contents, you can utilize the Version History feature in Microsoft 365, which allows you to view and restore previous versions of your files. Here’s how you can do it:

    1. Access Version History: Open your 2026 Database file in Excel. Go to the File menu, then select Info. Here, you should see an option for Version History. Click on it to view the previous versions of your file.
    2. Restore Previous Version: In the Version History pane, you can browse through the different versions saved. Select the version you want to restore, and you will have the option to view or restore it. If you find the correct version, you can restore it to replace the current one.
    3. Check OneDrive Sync: To ensure that your PC copy and OneDrive copy are the same, make sure that both are syncing correctly. If you notice that OneDrive is saving multiple iterations instead of overwriting, you might want to check your OneDrive settings. Ensure that the library is configured to be available offline and that you are using the latest version of the OneDrive sync app.
    4. Clear Cached Files: If you continue to experience sync issues, consider clearing cached files from the Microsoft Office Upload Center, as this can sometimes resolve syncing problems.
    5. Regular Backups: To prevent future issues, consider regularly backing up your important files to a separate location or using a version control strategy to keep track of changes.

    By following these steps, you should be able to restore your 2026 Database to its correct contents and ensure that both your PC and OneDrive versions are consistent.
