How do I make sure that my excel worksheet is not accessbile to others?  

That's a question that would be difficult to answer definitively without knowing a bit more about the context from which you're writing. Are you, for example, on a corporate computer system or your own computer at home? Do you use your own hard drive to store the file, or are you putting it in the cloud? Do you know how to password protect your spreadsheet (not that that method is foolproof)? Do you have a password protected computer or cloud service?

The answer to your question is buried in your answers to those questions.

If you need more specific help, come back with a more complete description of the context, i.e., answers to those questions.
