Steps
- Upload an XLSX or XLSM file - Browser repair works on ZIP-based Excel workbooks.
- Run diagnostics - The tool checks required workbook parts and worksheet files.
- Review repair status - Healthy, repairable, limited, and unsupported statuses explain what was found.
- Export recovered values - When possible, save readable sheet values into a clean workbook.
Before You Start
- Encrypted files cannot be repaired without the open password.
- Recovered workbooks preserve values, not every chart, macro, or formatting detail.
- For severe corruption, keep the original file and try Excel desktop recovery too.
