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.
