About NDJSON

Newline-delimited JSON — one JSON object per line.

NDJSON (newline-delimited JSON), also written JSON Lines or .jsonl, stores one self-contained JSON value per line. It's the format of choice for logs, data exports, and streaming pipelines because each record can be read independently. Our viewer parses every line locally and lets you browse records as a tree.
