Do you know which way is the best to remove Excel workbook protection without knowing password?

I think it should remove excel workbook protection at once with one click automatically. Just like the software introduced in the video, iSunshare Workbook Unprotect Genius, it could remove workbook structure protection password, sheet protection password and read-only password at one time with only one click on "Remove Password" button.
