ParquetView

Convert Parquet to JSON online

APIs and notebooks often want JSON. Parquet is what data teams ship. A full-file dump is usually the wrong move: nested columns explode in size. Convert the slice you need. Need a spreadsheet instead? Use the Parquet to CSV converter.

In ParquetView

  1. Open the viewer and drop the Parquet file.
  2. Hide columns you do not want. Exports include visible columns only.
  3. Filter a header, search, or run SQL so you only export the rows you need.
  4. Open Export and choose JSON.

Very large exports are capped at 100,000 rows so the browser stays stable.

What the JSON looks like

Each Parquet row becomes a JSON object. Column names are keys. Types that JSON cannot represent (large integers, timestamps) are serialized as strings or ISO dates where possible.
