Question details

The user needs to recover several weeks of spreadsheet data that vanished after a software update, despite autosave being active and the file being saved.

How to Recover Missing Excel Data That Disappeared After Saving

Product: Microsoft Excel
Device & OS: not provided
Scenario: The user updated their system or application, and upon reopening their saved workbook, discovered that recently entered data was completely missing.
Observed behavior: The saved Excel file opens successfully, but recent data and modifications are absent. Furthermore, local previous versions do not appear to be readily available.

Before you start

Immediately stop making new edits or saving the affected workbook to prevent overwriting any hidden temporary files or cloud version histories that might contain your missing data.

Solution 1Recommended

Restore from OneDrive or SharePoint Version History

If your workbook was synced to Microsoft cloud storage, you can access older snapshots of your file and restore the missing data.

Cloud storage services like OneDrive automatically save multiple versions of your files as you work. This is the most reliable way to recover data lost due to local sync errors or interrupted application updates.

Open OneDrive or SharePoint

Log into your OneDrive or SharePoint account via a web browser and navigate to the folder containing your affected Excel file.

Access Version History

Right-click the Excel workbook and select 'Version history' from the context menu.

Restore or Download

Review the list of previous versions organized by date and time. Click the three vertical dots next to the correct version and choose 'Restore' to replace the current file, or 'Download' to save it as a separate copy.

Restore from OneDrive or SharePoint Version History

Check AutoSave Status: This method relies on the AutoSave feature being toggled on and successfully syncing to your Microsoft account prior to the update.

Solution 2

Recover via Unsaved Workbooks and Temporary Files

If cloud synchronization failed or wasn't enabled, Excel's local AutoRecover system may have retained a temporary backup.

Frequently Asked Questions

Why did my saved Excel data suddenly disappear?

Data loss in a saved file often occurs due to OneDrive synchronization conflicts, saving to a temporary folder instead of the intended directory, or unexpected application crashes during a software update before changes could fully commit.

Can I recover an overwritten Excel file if I don't use OneDrive?

Yes. If Windows File History or System Restore is active on your device, right-click the file in Windows File Explorer, select 'Properties', and check the 'Previous Versions' tab to restore an older local snapshot.

Does AutoSave guarantee I won't lose my Excel data?

Not completely. AutoSave requires an active internet connection and seamless cloud syncing to OneDrive or SharePoint. If your connection drops or your cloud storage is full, local changes might not upload, potentially leading to data loss if the file is closed abruptly.
