How to Repair a Corrupt Excel File
- Keep the original file untouched, then upload a copy in XLSX or XLSM format.
- Run the browser-based diagnostic to inspect the workbook package and its worksheet files.
- Review the reported status and which workbook parts remain readable.
- When recovery is available, export the readable sheet values into a clean XLSX workbook.
What Browser-Based Repair Can Recover
Modern XLSX and XLSM files are ZIP packages containing workbook and worksheet data. This tool can inspect those package parts and recover readable cell values when enough of the structure remains. It does not recreate every style, chart, macro, or formula result, and it cannot open an encrypted workbook without its password.
Keep the damaged original so you can also try Excel desktop's Open and Repair command or restore an earlier version from backup. A recovered download should be treated as a clean copy of the values that were still readable, not as a byte-for-byte repair of the source.
