How to Convert Parquet to JSON Online (Free, No Upload)

Convert Parquet to JSON in seconds, right in your browser, with no install and no account.

Parquet is made for analytics engines, not for apps and APIs. If you want to use the data in a web app or send it to an API, you need JSON.

The converter reads the Parquet file and its column types and writes JSON records, one object per row, with numbers, dates and true/false values kept correct.

Your file is processed in your browser and is not uploaded to a server, so it is safe to use with customer or business data.
