A real JSON linter and toolkit for the terminal. Validate syntax, pretty-print, minify, compare files, list keys, and extract values by path — all powered by python3.
| Command | Description |
|---|---|
| --------- | ------------- |
jsonlint validate | Check JSON syntax — reports type, element count, file size, and shows error context on failure |
jsonlint format | Pretty-print JSON with 4-space indentation |
jsonlint minify | Compact JSON (remove all whitespace), shows bytes saved |
jsonlint diff | Deep structural comparison of two JSON files — shows added, removed, and changed values with dot-paths |
jsonlint keys | List all top-level keys with types and value previews |
jsonlint extract | Extract a value by dot-path (e.g. config.database.host), supports array indices like items[0] |
