How to use NDJSON Converter
Work with line-delimited records instead of one JSON root. Blank-line handling is explicit, and each accepted record remains an ordinary JSON value.
- Enter input.
- Choose the settings for ndjson converter, then run the tool.
- Review the result and any limitations before copying or downloading it.
Good to know
- 100,000 source characters, 5,000 records, 10,000 total values and depth 40.
- Line breaks inside strings must be escaped. JSON numeric precision applies; this does not ingest logs or run code.
- Processing is local. Output is limited to 1,000,000 text characters unless a stricter file limit is stated.
Common questions
Can each line contain an array or primitive?
Yes. Every nonblank accepted line is independently parsed as one JSON value.
Is this input sent to a server?
No. The application processes this input inside your browser tab and does not save it to persistent storage.
