Once a workbook is open breaking sheet and workbook protection takes moments
because the system used is so weak so forget it and certainly don't waste
your money on buying softare that claims to improve matters.

Workbook open passwords are better but still very breakable with cheap
commercial software such as passware.

Tp see how simple it is follow

I am looking for some code to give protection against basic
attempts at hacking into an excel workbook. (Sheet, workbook, and VBA
code protection) For example to protect against brute force password
hacks.

I found one such program for like ten dollars and found it did
not work at all. It only crashes the workbook when opened. (Glad I
found that out on the demo!)
