How to Recover an Excel File Overwritten by a OneDrive Sync Conflict
Question details
The user needs to recover local Excel file edits that were overwritten due to a OneDrive synchronization conflict.

- Product
- Microsoft Excel / OneDrive
- Device & OS
- not provided
- Scenario
- A synchronization conflict in OneDrive has overwritten the local version of an Excel file with the cloud version, resulting in the loss of recent local edits.
- Observed behavior
- The local Excel file now displays the cloud version's data instead of the user's latest local work, and standard version history might not immediately reveal the missing data.
Stop editing the affected file or folder immediately and do not delete the existing file to prevent permanently overwriting your recoverable data.
Use the 'Restore your OneDrive' Feature
Roll back your entire OneDrive to a previous point in time to undo the conflict overwrite.
If individual version history does not contain your lost edits, you can restore your entire OneDrive to a state before the sync conflict occurred. Note that this will revert all files and folders in your OneDrive to the selected date.
Go to the OneDrive website in your browser and sign in with your Microsoft account.
Click the Settings (gear) icon in the upper-right corner and select 'Restore your OneDrive'.
On the Restore page, choose a date from the dropdown list (such as 'Yesterday' or 'Custom date and time') that corresponds to a time before the sync conflict happened.
Review the activity chart to identify the exact moment of the conflict, then click 'Restore' to revert your OneDrive library to that previous state.

Check OneDrive Version History
Manually check the version history of the specific Excel file to see if the local copy was saved as a distinct version.
Contact Microsoft 365 Administrator (For Business Users)
If standard recovery methods fail, business users can request cloud backend recovery via their IT admin.

Frequently Asked Questions
Why did a OneDrive sync conflict happen with my Excel file?
Sync conflicts typically occur when a file is edited on multiple devices simultaneously, or when offline edits are synced back to the cloud where a newer version already exists. OneDrive struggles to merge these changes, sometimes resulting in one version overwriting the other.
Will I lose my other files if I use the 'Restore your OneDrive' feature?
Yes, restoring your OneDrive will roll back all files and folders in your entire OneDrive library to the selected date. Any new files created or changes made after that specific date will be undone, so it is recommended to back up recent work before proceeding.
Where else can I look for my overwritten Excel data?
You should check both your local Windows Recycle Bin and the OneDrive Cloud Recycle Bin (accessible via the left sidebar on the OneDrive website). Sometimes, conflict copies or older versions are automatically moved to the recycle bin during a sync anomaly.
