Anybody knows if there are other ways to crack a password of a protected sheet in excel? I have been using these codes ever since but now, it doesn\'t seem to work anymore.
Excel has updated their sheet protection security in Excel 2013 and newer so this macro won't work anymore, see here.
From the link it sounds like if you save the file as an xls file (Excel 1997-2003) it is forced to drop the newer security as it wasn't compatible with the file type. You could then run your macro.
Saving as an older file version may make certain parts of the workbook not work.
