Thanks in advance

Excels offers a protection functionality, have a look here. You can use the menu entries in Tools -> Protection. I tried it with excel 2003 and it worked fine. More recent excel versions should offer the same (maybe enhanced) functionality.

I would assume you would get more accurate and faster answers on superusers.com for questions related to using software instead of developing it.
