Splitting data into 5 sheets

Hey Everyone!!

I need to build a macro for excel to make my life easier. I've never done it and I am having a hard time figuring out how to get started. Could you point me in the right direction?

I get lists of customers every month and I need to break them into 5 additional sheets, Customers with birthdays listed, Customers with birthdays and emails listed, customers with emails listed, customers with sales date listed and customers with no sales date listed.

Thank you!!
