Export/Import users

I want to export my user mailboxes so I ca see the format it needs to import a bunch of new users. So I export everything. When I try to open with xls, it does not come out right.
Is there a template I am suppose to use?
I know its csv file, and Ill import it csv, but to create a new user import list is getting very difficult.
