Hello natalietwicecreative2014,
Thanks for reaching out to us!
Unfortunately, at this time, there isn’t a straightforward way to modify the attendee CSV export. It is currently on our radar to make this process a little simpler, however it currently requires modification of core files. If you would like to make those modifications, the places to start would be:
- TribeEventsTicketsPro::ajax_handler_attendee_mail_list()
- TribeEventsTicketsPro::maybe_generate_attendees_csv()
I’m sorry I wasn’t able to give you a direct solution but hopefully this will get you pointed in the right direction.
Thanks!
