You can use almost any application listed through the database of Software Informer. Access the results list (narrowed down based on your search) and then pick an application from the list. Tick Free only if you want just the free ones. Once the software has been chosen and installed, add the encrypted file and let the software do the rest.

I find something seeming fine on the net.
1. change the filename extension to .zip, and open it with Winrar
2. Open the folder named xl\worksheets
3. Open each xml file with editor
4. Search sheetProtection and delete the whole sentence
5. Change the file back to .xlsx

Hope this helps!
