What problem does it solve?

JN provides a compact, pipeline-friendly way to read, transform, and write NDJSON data, enabling streaming ETL workflows without heavyweight data stores.

Core Features & Use Cases

  • Read data sources and convert to NDJSON (jn cat) from CSV/JSON/Excel/YAML.
  • Transform and filter NDJSON with jq-like expressions (jn filter).
  • Write NDJSON to JSON/CSV/Excel/YAML (jn put).
  • Display results in tabular form or VisiData integration (jn table / jn vd).
  • Supports simple batch/slurp style aggregations with -s option (jn filter -s ...).

Quick Start
