Parquet to CSV

Convert your Parquet files to CSV format for use in Excel, Google Sheets, and other tools. Files are processed locally in your browser.

How it works

Drop a .parquet file onto the page or choose one from your device. It is decoded in your browser and a .csv file is downloaded automatically. Nothing is uploaded.

Why convert Parquet to CSV

CSV is the universal exchange format. A Parquet to CSV conversion lets you open columnar data in Excel, Google Sheets, or any tool that reads comma-separated values, with quoting handled automatically.

Private by design

The file never leaves your browser — there is no server and no upload. Conversion runs locally using WebAssembly.
