• The previous content is replaced with new data.
• Excel's built-in undo cannot revert the file if the document was closed or saved multiple times.
• File corruption risk increases if the overwritten file was in use during a crash or system failure.

Recovery Methods

• Previous Versions / Backup: Restore the overwritten file from Windows File History, OneDrive, SharePoint, or other backup servs.
• Excel AutoRecover: If AutoRecover is enabled, temporary versions may allow restoration of the previous content.
• Professional Recovery Software: Advanced recovery tools can attempt to reconstruct overwritten file sectors. Success varies depending on the extent of overwriting.
• Data Recovery Servs: For critical files, professional servs like Jiwang Data Recovery can attempt low-level recovery from storage media.

Extent of Data Recovery

• Partial recovery is common; key tables, formulas, and metadata can often be restored.
• Files overwritten multiple times may result in limited or partial content recovery.
• Backups or snapshots provide near 100% recovery if available.
• Professional tools increase chances of retrieving most critical data.

Estimated Recovery Costs

• Restoring from backup or previous versions: Free to minimal cost.
• Professional recovery software: $50–$200 depending on file size and complexity.
• Professional data recovery servs: $150–$500 for severely overwritten files or high-value workbooks.

Prompt action reduces costs and increases the likelihood of successful recovery.
