How to Recover a Missing Excel Workbook and Check for Malware

Product: Microsoft Excel
Device & OS: not provided
Scenario: A critical financial workbook has disappeared from the user's device or cloud storage, requiring recovery and an investigation into the cause.
Observed behavior: The Excel file is completely missing from its originally saved location, raising suspicions of unauthorized deletion by malware, antivirus software, or Office crashes.

Before you start

Immediately stop saving new files to the drive where your Excel workbook was located to avoid overwriting the missing file's data before recovery.

Solution 1Recommended

Locate the File in Cloud Storage or Recycle Bins

Check the most common locations where deleted or misplaced files are temporarily stored before investigating deeper system issues.

Often, files are accidentally moved or deleted by user error or cloud synchronization glitches rather than malware. Checking the local and cloud recycle bins is the fastest way to recover your workbook.

Check the Local Recycle Bin

Open the Recycle Bin (or Trash on Mac) on your desktop. Search for the exact name of the financial workbook or sort by the '.xlsx' extension. If found, right-click the file and select Restore.

Review OneDrive or SharePoint

If the file was saved to a cloud service like OneDrive, SharePoint, or Dropbox, log in via your web browser. Navigate to the cloud service's specific Recycle Bin or 'Deleted files' section to restore the document.

Check Version History

In OneDrive or SharePoint, if you find an older or corrupt version of the file, right-click it and select 'Version history' to restore a previous, fully intact version.

Locate the File in Cloud Storage or Recycle Bins

Syncing Errors: If you use Teams or SharePoint, check if the file was moved to a different channel or folder by another collaborator.

Frequently Asked Questions

Can a Microsoft Office crash delete my locally saved Excel file?

Generally, no. While an Office crash can cause you to lose unsaved changes or corrupt your current session, it will not delete a previously saved local file. Deletions are typically caused by user actions, syncing errors, or third-party software.

How do I find temporary Excel files to recover my lost workbook?

You can search for temporary files by opening Excel, navigating to File > Info > Manage Workbook, and selecting 'Recover Unsaved Workbooks' to see if a backup draft exists in the local AppData folder.

Could my antivirus software have deleted my Excel workbook?

Yes, if your antivirus software mistakenly identified a macro or script within the financial workbook as malicious, it may have automatically quarantined or hidden the file. You should check your antivirus quarantine logs to restore it.
