How to protect excel sheet with a strong and recovery proof password!

Hello Excel Experts!

Greetings!

I developed some modules in MS EXCEL 2007. I wish to protect the excel sheet with a strong password which should be unrecoverable. One cannot unprotect the sheet using any software ex. passware etc.

Please guide, is it possible to protect excel sheet with recovery proof and very strong password.

Thanks in advance.

No it is not. You may perhaps buy software to 'compile' the workbook into an executable file.

Dear Izandol,

Thank you very much for the information.

Can you please explain more regarding the conversion of excel file to exe file, because this point is very new for me.

I do not use these programs but you may buy such as Excel to Exe or Excel Compiler.

Thank you very much for the information.
