The best way to repair a corrupt XLS spreadsheet is to first try Excel’s built-in Open and Repair feature. If the file is badly damaged or won’t open, a tool like SysInfo Excel Recovery Software can help recover worksheets, formulas, charts, and formatting without changing the original file. Simply add the corrupt XLS file, scan it, preview the recovered data, and save the repaired workbook safely. More: https://www.sysinfotools.com/recovery/excel-recovery.php
