Parquet to JSON converter

Convert your Parquet files to JSON format for APIs, web apps, and data interchange. Files are processed locally in your browser.

How it works

Drop or choose a .parquet file; it is decoded locally and a .json file containing an array of row objects is downloaded. No upload.

Why convert Parquet to JSON

JSON is the common language of web APIs and JavaScript apps. Export Parquet to a JSON array for use in APIs, front-end applications, and data interchange between services.

Private by design

The Parquet file is decoded in the browser itself — no server round-trip, no upload. WebAssembly does the decoding locally.
