JSON to NDJSON

NDJSON is a convenient format for storing or streaming structured data that may be processed one record at a time.

  • Each line is a valid JSON value
  • Line separator is ‘\n’

1. Convert JSON to NDJSON?

cat test.json | jq -c '.[]' > testNDJSON.json

With this simple line of code, you can convert and save files in NDJSON format.

Note: jq is a lightweight and flexible command-line JSON processor.

jq can choke on very large files, and be slow. For these situations I made json2nd.

Thanks for sharing @draxil !
