Parquet to CSV converter

Convert your Parquet files to CSV format for Excel, Google Sheets, and any spreadsheet tool. 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 remains 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.

Works with any Parquet compression

Snappy, Gzip, Zstd, LZ4, LZ4_RAW, and Brotli inputs are all handled — the decoder picks up the codec from the file automatically, so there is nothing to configure.

Private by design

Your file never leaves the browser — no server, no upload. The conversion itself runs locally through WebAssembly.
