They didn't give me gpx files a few years ago either. I seem to remember it being a json or a csv, I can't remember which right now. Was easy to parse it to get the information I was after.

What the hell?? Seriously? There's no way to get my historical location data anymore? I always assumed I could rely on my google location history as a way to look back at where I've been throughout my life..

Seems like you are right, when configuring an export the "file type" choice of your location history data is grayed out.

Uh.. what format does it give you the data in then?
