So after I messed up and tried to do this with “your Twitter data” (which includes everything about you and DMs and stuff that shouldn’t really go on a public visible archive. Oops.
Link about the data format change: https://kyleconroy.com/your-twitter-data
You can get your Tweet Archive (what you need for this project) here: https://twitter.com/settings/account
The one that gives you *everything* (be careful where you put that) is https://twitter.com/settings/your_twitter_data
Thanks, this should work now.
