JSON Lines / NDJSON

JSON Lines and NDJSON Converter

JSON Lines (also called NDJSON or JSONL) puts one JSON value on each line, as in log files, streaming APIs and BigQuery exports. Turn an array into lines, or lines back into one array.

How to use it

1. Paste a JSON array, or choose JSON Lines → JSON and paste lines.
2. Read the result in the Output box.
3. Copy it or save it as .jsonl or .json.

What it does

• Both directions
• Reports which line is broken
• Blank lines are skipped
