How to get all submsissions in two languages in xls

I need a copy of all data in two languages used in form (russian and kazakh)

At the present we do not have a language filtering option for the submissions, normally the translation and language selection is at the form level.

You can get the language used in a form using conditions then pass the language value to a hidden field which can then be used to filter it our, but this wont apply to already submitted information.

In this case it would require manually separating the various submissions.
