JSON export / NDJSON / JSONL

Free online JSON to NDJSON / JSONL converter

Write one independently parseable event per line. Open your JSON locally, then inspect the format-specific output and download the full artifact.

Privacy-first processing: pasted or opened JSON stays in this browser tab and is not uploaded to our servers.

Event array JSON

[
  {
    "event": "open",
    "context": {
      "tab": 1
    }
  },
  {
    "event": "close",
    "context": {
      "tab": 1
    }
  }
]

Operation

Write one JSON value per line.

  • Format: NDJSON / JSONL
  • Root array: each item becomes one line

Expected NDJSON

{"event":"open","context":{"tab":1}}
{"event":"close","context":{"tab":1}}

Caveat: The output is not a single JSON document; parse each line independently.

Format constraints

Requires a root array. Each item becomes one line without an enclosing array; an empty array yields an empty file.

Opening a large file and exporting it are separate operations. Output size and compatibility depend on the source shape and the selected format.
