For myself, it took some serious google scouring to finally find this. Downloading the hangouts backup is easy, but I was all over the place trying to find something that made formatting the json file google provides easier. This guy's done it and I was able to get a years worth of chat logs onto about 70 pages front and back. What's nice is you can just download the .txt and avoid all the photos.
