FAQ
- How do I convert a Parquet file to JSON format online?
- Upload or drag your .parquet file into the converter. Preview the data, optionally filter with SQL, then click 'Export JSON' to download the converted file instantly.
- What JSON structure is generated from Parquet files?
- The converter exports an array of JSON objects, where each object represents a row from the Parquet file. Column names become JSON keys, and values are properly typed.
- Where is my Parquet data processed during JSON conversion?
- All conversion happens locally in your browser via WebAssembly. Your Parquet file is never uploaded to any server, ensuring complete privacy.

- Yes. Use the built-in SQL editor to filter, transform, or aggregate your Parquet data with SELECT, WHERE, and other SQL clauses before exporting to JSON.
- How do I handle large Parquet files when converting to JSON?
- Use SQL queries with LIMIT or WHERE clauses to export only the data you need. This reduces the JSON file size and speeds up the conversion process.
