BAS enter text from spreadsheet?

Hi,

I'm trying to create a bot/script in BAS to signup to a website automatically.

I need username + password. Is it possible to use an or many excel file(s) (or other spreadsheet software) containing usernames and passwords and make BAS choose from the file randomly when the signup bot is executed?

If not is there another way to make it not use the same text every time it's executed?

Thank you
