i search a csv export plugin

is there’s an export plugin on wordpress that will allow me to customize the export process:

i use a booking event plugin which gives me the booking data in a csv.
but i gives every booking an own id.

is there a possibility to have 1 id for one user, which has 3 bookings, automaticly?
or an easyway to do that in exell?

can anyone tell me a plugin which can do this?
