> I'm not sure if Things lets you export tasks, but if they do I'm more than happy to run a one-time custom import for you (or any other Things user). There's also the simpler way, which is copying a bunch of tasks to your clipboard and hitting ⌘+Shift+V in Godspeed to paste tasks from clipboard. It'll respect indentation and bullet characters.
The local Things database is just a sqlite database. https://culturedcode.com/things/support/articles/2803570/
