Arrow to Parquet Online — Upload Arrow, Validate with SQL, Export Parquet

Convert Arrow to Parquet online (and export CSV, JSON, or Parquet)

Need to convert Arrow files quickly? Upload your file, explore it instantly, and export as CSV, JSON, or Parquet.

No installs. Every upload becomes a queryable table (dataset) with SQL, search, and sorting.

How it works

1. Upload a Arrow file (or open via URL if supported).
2. Preview the schema and data in seconds.
3. Export as Parquet (or choose CSV, JSON, or Parquet).

Query with SQL, search, and sort

Run SQL on your file (example): SELECT * FROM dataset LIMIT 50;

Use search, sorting and pagination to validate columns, spot issues, and find the rows you need.

You can also export SQL query results as CSV, JSON, or Parquet.

Exports and full-dataset access

Exports support CSV, JSON, or Parquet — including exporting the result of your SQL query.

Free preview lets you validate quickly. When you need full-dataset exports/search/SQL, unlock via Day Pass or Pro (instant API key, no account).
