A Corrupted XLS file may have difficulty opening, display errors or showing lack of spreadsheet data. It occurs due to interruptions during saving process, accidental shutdown, storage issues, or corrupted file info. Before making any attempts to repair the file, make a duplicate copy of the file to preserve the original one. Open Microsoft Excel, go to File, click Open and Browse, select the damaged spreadsheet and click on the arrow near the Open option. From there, select Open and Repair and pick Repair. In case it doesn’t work, you may use Extract Data to retrieve the data and formulas present. Alternatively, you could look for an older version of the file or backup.
