csv tsv json jsonl yaml yml parquet avro orc arrow xlsx

A tabular object opens as a notebook: a SELECT * over it, the rows in a virtualized grid with column summaries, and a chart of what came back.

A parquet file opened as a notebook, the query above its rows


Queryable with SQL	`parquet` `csv` `tsv` `json` `jsonl` `xlsx` `avro`
Grid and charts, no SQL	`orc` `arrow` `h5` — the cell says so rather than failing

A csv is sniffed for its delimiter and its header; a json file that holds an array of objects reads as rows, and one that does not opens in the JSON viewer instead, virtualized so a large document scrolls.

Next: statistics.
