I love your tool. If you want a slightly more structured version of Gists that speaks parquet try my own tool, csvbase :). I pasted this data in as https://csvbase.com/calpaterson/opcodes-6502 and you can get parquet by adding .parquet to that (https://csvbase.com/calpaterson/opcodes-6502.parquet)

Here's datasette lite running off that file:

Really nice when webby stuff works together
