How can I reverse the order of the Facebook chat history when I export it/download it? It is in the wrong order (newer messages are upwards)

If you have a chat like this in Facebook:

- Hi Alice- Hi Bob- How are you?- Fine, thanks for asking

After downloading it, it comes out like this

- Fine, thanks for asking- How are you- Hi Bob- Hi Alice

Pretty impractical to read, especially if it is a long chat log you are reading. Any way to reverse the order of this?
