I have a workbook which i really want to protect.
i dont want any formulas to be seen and tampered with.
simply hiding/locking cells and protecting the sheet is not secure enough. within minutes of googling crack password, i was able to find a macro that unlocks the sheet.

is there something out there that can really secure your workbook.
i found something called XLS Padlock (http://www.xlspadlock.com/).
seems great. has anyone had any experience with it

thanks
