export / import csv datatable ingame

I got a datatable which contains informations of my game. I was wondering if it was possible to :

1- from a modfied csv file of this datatable, bring it somwhere in my exported game’s file in order to be read by my game. Kind of patch of my game which actualise it with a csv instead of a real patch made with the unreal editor.
2- export this datatable as a csv during the game (not on the editor) in order to “save my game” if the point 1 is possible.

Thanks and sorry for the bad english.
