Excel data behind password protected page

I am new to working with WordPress and I am unsure if it is able to do what I need it to do.

We have families that have spending accounts with us and currently they have to call to confirm how much is in their account. We have all this information stored in an excel sheet and were wondering if we would be able to export this information onto our website so that when a password is entered, they would be able to see how much money is in their personal account.
