Unprotect VBA on XLSM File

source: https://stackoverflow.com/questions/1026483/is-there-a-way-to-crack-the-password-on-an-excel-vba-project/31005696#31005696

For a .xlsm or .dotm file type you need to do it a slightly different way.

1. Change the extension of the .xlsm file to .zip.
2. Open the .zip file (with WinZip or WinRar etc) and go to the xl folder.
3. Extract the vbaProject.bin file and open it in a Hex Editor (I use HxD, its completely free and lightweight.)
