About bigCsv
Open a multi-gigabyte CSV, TSV, Parquet or JSON-lines file in the browser: row count, column types, the first 100 rows, a profile of every column, and any SQL you like (GROUP BY, window functions, regex) on DuckDB. Download results as a smaller CSV. The file is read from your disk and never uploaded.
Runs entirely in your browser: your SQL and files are not uploaded. Signed-in members can keep a history of runs and results.
Built on open-source libraries: DuckDB-Wasm.
