How to export repeated field group into multiple rows

Hello I have created custom user fields using repeater field groups. I need to export each field group into separate rows

A user can have many reading partners from many families. The partners can have a family name, and a type whether he / she is the father / mother or the child in that family

Sample image

Any idea how can i export these repeater fields or know any plugin that can do that ?

I tried wpallexport plugin but repeated group fields was just lumped into on column.
Thank you
