Parquet to JSONL Converter
/parquet-to-jsonlConvert Apache Parquet files into JSONL (NDJSON) streams, one JSON object per row, for pipelines and ingestion.
Moving columnar data into streaming pipelines usually means converting Parquet to JSONL first. This converter emits one JSON object per row from a Parquet file, ready for ingestion. It preserves the schema's field names and types. Conversion runs entirely in your browser.

FAQ
Frequently asked questions
Everything you need to know about parquet to jsonl converter.
Do column names stay the same?
Yes. Every Parquet column becomes a JSON key, and each row becomes a single JSONL line, so the schema is preserved exactly.
How are null values written?
Null values are written as JSON null, while empty strings remain empty strings, exactly as stored in the Parquet file.
Why convert Parquet to JSONL?
JSONL streams naturally into data pipelines, serverless functions, and log ingestion systems that expect one JSON object per line.
Does this work with compressed Parquet?
Yes. The WASM reader handles the standard Parquet compression codecs such as Snappy, so warehouse exports convert without extra steps.
Is my data sent to a server?
No. The file is decoded entirely in your browser using WebAssembly and Apache Arrow; nothing is uploaded.
