fix button action export for csv

[PClmnt]

Description

CSV data wasn't being exported correctly, so added the csv headers and converted the data

This looks like it'll work just fine, but I think it would be better to do this on the server side like we do our other exports - the server already has the utilities needed. Check out the view controller for an example.

Nice one, definitely better doing it on the back end 👍
