1. Navigate to the folder containing the XLSX file you want to repair.
2. Right-click the file and select "Copy" and then right-click on a
blank space within the folder and select "Paste." This action generates a
backup copy of the corrupted file.
3. Open Microsoft Excel 2007 or later.
4. Click the "Office" button in the top left corner of the window and select "Open."
5. Navigate to the folder containing the copy of the XLSX file you
generated previously and select it by single-clicking its icon.
6. Click the arrow located to the right of the "Open" button and select "Open and Repair."
7. Select "Repair." If you previously attempted this method and the
process failed, try to extract only the values and formulas by selecting
"Extract Data" instead. Regardless of the method you choose, your data
will appear on the screen within a few seconds if the process completes
successfully

Receiving ‘Excel found unreadable content in filename.xls’ in your excel workbook but unable to fix this error? Well you can fix this by trying manual as well as automatic solution. For manual solution you must try these steps:

Firstly you need to change the File Extension of Your Excel Sheet. Sometimes, the problem is occurred due to the unsupported file extension of your excel file. To check the support of xlsx extension, go to the ‘My Computer’. Browse ‘Tools >> Folder Options >> File Types’. Make sure that the ‘xlsx’ extension is included there or not. If not then rename this file and change ‘.xlsx’ to ‘.xls’.
Use Open and Repair option of excel:
For this, just open the Excel workbook and then go to ‘File >> Open option. Choose the file which you want to open but don’t make double tap on it. After then go to the ‘Open’ dialog box and then select ‘Open and Repair’ option from there. This process will fix the corrupt excel spread sheet and open it normally.
The chances are very less for the perfect conversion, but yes your damaged file could be recovered of course for sure.
