Absolutely love this. I have a whole bunch of similar tools for importing stuff from different services into SQLite but I never got up the courage to take on Jira!

Here's my github-to-sqlite tool which imports GitHub Issues https://datasette.io/tools/github-to-sqlite - being able to query them in a local SQLite database is super-handy. I run a demo instance of the resulting database here: https://github-to-sqlite.dogsheep.net/
