Recovery Options

• Restore from Backup: If backups or previous versions exist on OneDrive, SharePoint, or local storage, recovery is highly feasible.
• Professional Recovery Software: Specialized Excel recovery tools can scan for overwritten workbook data and attempt reconstruction.
• Manual Reconstruction: Without backups or version history, reconstructing lost data manually may be necessary, although it is time-consuming and prone to errors.

Success Rate of Recovery

• Backup or version history restoration: 95–100% success rate for restoring formulas, values, and charts.
• Professional recovery tools: 70–90% depending on workbook complexity and overwrite extent.
• Manual reconstruction: Variable success; depends on available reference information.

Is It Worth Recovering?

Recovery is generally worth attempting if: www.sosit.com.cn

• The old workbook contained critical or irreplaceable data.
• Formulas, macros, or VBA modules are essential for reporting or automation.
• Recent backups or version history exist that increase the likelihood of successful recovery.

If the workbook contained only minor or easily re-creatable data, recovery may not be cost-effective. www.sosit.com.cn
