How to repair a corrupt Excel file

Although Excel is very useful, it cannot protect the created documents from external threats and corruption that lead to complete data loss. Microsoft Excel recovery software is one of the best solutions to recover your corrupt or damaged .XLSX file either on a PC or online repair on any platform with a browser.

With the Recovery Toolbox for Excel, you can easily recover the corrupt .XLXS file manually without involving a system administrator or having prior technical knowledge by using the recovery methods recommended in this blog post.

The Reason Behind the Issue: “The file could be corrupted or unsafe.”

The XLS/XLSX files can be damaged manually or due to the following reasons:

  • Virus injection
  • Incorrect antivirus cleaning of files (True-False detection)
  • Hardware failures
  • Power shortages
  • The USB device is incorrect; unplug it.
  • Microsoft Excel bugs
  • Incorrectly working third-party tools with Excel data files

Solutions to recover damaged XLXS files.

Method #1: Repair a corrupted workbook in Excel

When Microsoft Excel detects a corrupted workbook upon opening, it automatically starts File Recovery mode and attempts to repair the workbook. If File Recovery mode doesn’t start, try using this manual process to recover your workbook:

  1. Click File > Open.
  2. Click the location and folder that contain the corrupted workbook.
  3. In the Open dialog box, select the corrupted workbook.
  4. Click the arrow next to the Open button, and then click Open and Repair.
  5. To recover as much of the workbook data as possible, pick Repair.

If Repair isn’t able to recover your data, pick Extract Data to extract values and formulas from the workbook. If neither automatic nor manual repair works, try the following recovery methods that can help salvage your important data.
