Protect excel sheet

[kangaris]

Hello,

I have an excel sheet and I am trying to find the most secure way to protect it from being modified. I know that sometimes even if you lock the cells if someone save it as then the excel can be modified. Can somebody advise?

Excel is NOT a secure platform. If someone really wants to modify it, they can.

The best way to prevent modification is to write your spreadsheet so the end user likes things the way that they are.

Hello Mike,

I agree with what you said. However, I am not really concerned about changing the spreadsheet but about copyrights since I believe my excel sheet is a great powerful tool (almost working as a software) which anyone can claim copyrights if I don´t.

That is even worse. Those people who are clever enough to claim copywrite for your coding will also be clever enough to bypass any VBA security. (Or just about anything else.)

And you need to claim copyright in any case. If you copyright the work before they crack it, then it doesn't matter if they crack it, they can't claim its their code. (Or my thinking may be more applicable to music than to software.)

Totally agree! That makes sense. I should be less worried. Thanks Mike
