What's the messiest data file you'd throw at File SQL?

Curious what real-world files people are dealing with. If you had a "SQL for files" tool sitting in your editor, what would be the first ugly thing you'd try to query?

A 20 GB Parquet dump? A folder of nested JSON logs? A CSV with 400 columns and no header? Something worse?

Reply with the file (or describe it) — I'll test File SQL against the weirdest ones and post results here. Free stress test 🙂
