I wish, when exporting a list that there was a checkbox allowing me to switch from plain English column headings to import friendly column headings.
For example, I have exported a student list with User ID, First Name, Last Name, and Grad Year so that locker numbers can be entered in Excel and the CSV then be imported to mass fill those numbers. It sure would be nice to have a checkbox that exports those field column headings as user_id, firstname, lastname, and grad_year.
