Need a hand with .CSV Export

(DeLoy ) #1

In Gravity Forms the csv file of form submissions I export is perfect with all the data but I need the format of the csv. to be a certain way , how do I accomplish this? I have been reading the docs for gform_entries_field_header_pre_export but I just cant realize the code I need to enter to achieve this. can I get a hand ?
I need the header to display first name , last name, email address for 20 entries. here are before and after screenshots of what i am trying to accomplish.

Thanks a bunch
