JSONLint

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.

Commands

Command	Description
jsonlint validate <file>	Check JSON syntax — reports type, element count, file size, and shows error context on failure
jsonlint format <file>	Pretty-print JSON with 4-space indentation
jsonlint minify <file>	Compact JSON (remove all whitespace), shows bytes saved
jsonlint diff <file1> <file2>	Deep structural comparison of two JSON files — shows added, removed, and changed values with dot-paths
jsonlint keys <file>	List all top-level keys with types and value previews
jsonlint extract <file> <path>	Extract a value by dot-path (e.g. config.database.host), supports array indices like items[0]

Requirements

• python3 (uses json stdlib module)
