Parquet Viewer reads Apache Parquet, CSV, TSV, JSON, and JSON Lines, and exports to CSV, JSON (JSONL), and Parquet — so you can convert back and forth between the common data formats, all in your browser with nothing uploaded. Pick a conversion below, or just open the viewer and export to whatever format you need.
