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

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

Parquet files are great for machines but impossible to open in a text editor or most spreadsheet apps. When you just need to look at the data, you need a readable format.

The converter reads your Parquet file, including its column types, and writes a standard CSV that opens in Excel, Google Sheets or any text editor.

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.
