[zub009]

Hi,
how safe is it to sell our project in excel format excel protected sheet can be cracked down and anyone can recover the password and see the code or formula. like given in the below link

{moderator edit: link removed}

How can we protect it in such a away so that nobody can crack it down.

Is there any front hand we can use in which the back hand copy of excel sheet can be corrupted or anything else.

please advise. regards.

There is no way to make a 100% protected Excel sheet. As long as whatever you distribute contains the entirety of your code, someone who is motivated can find a way to reverse engineer it to take your formulas/data/logic/code.

Additionally, please remove the link to that article. It is against forum rules to discuss how to break password protection here.

I have edited out the link. Please be a little more cautious in future; instructions on how to circumvent protection, or references to such instructions, are a big 'no no'.

Rule 11 applies...
