How to tell when a tweet is an answer to another tweet?


#1

Hello.
I’m not a developer, but because of a research I downloaded my personal archive from twitter, and now I’d need a way to filter tweets so to be able to tell which ones are “pure” (written and sent from scratch) and which ones are an answer, a comment to another tweet. Is there a way to do that? Thanks.
(hope I picked the right category for the topic…if not, apologies)
