What is the “Excel Found Unreadable Content” Error?

Excel discovered content in the xxx.xlsx file that was unreadable. Do you wish to retrieve the information contained within this workbook? An Excel file that is either damaged or corrupted is typically the cause of an error. A sudden power outage, a problem with the network, an abrupt shutdown of the system, and other factors can all lead to the corruption of an Excel file.

There is also the possibility that the error will occur if you attempt to open the file with an incorrect extension. When creating Excel files, using Open XML is one of the many potential causes of this error. Other potential causes include a wide variety of other factors. It is possible for corruption to take place in any part of the spreadsheet.

Formulas, the formatting of the cells, or even the macros themselves could be the source of this issue. Another possibility is that a spreadsheet has multiple instances of corruption. It is also possible that the level of corruption will increase if you upgrade from an earlier version of Excel to a later version. Excel 2003, for example, makes it simpler to manually handle this error than Excel 2010, which makes it more difficult to do so.

How to Fix “Excel Found Unreadable Content” issue

Attempt to Open and Repair the Workbook

1. Launch Excel (without opening a file).

3. Browse to locate the problematic file.
4. Instead of double-clicking the file, click the arrow next to the Open button, then select Open and Repair.

Check for External Links or Broken References

Save the File in a Different Format

Use Excel’s “Recover Unsaved Workbooks” Feature

1. Open Excel.
2. Go to File > Open > Recent.
3. Scroll down and click on Recover Unsaved Workbooks.

Utilize Previous Versions

Consider Third-party Recovery Tools

1. If none of the above steps work, consider using third-party recovery tools.
