JSON Pretty Features

Six tools, one continuous workflow. Format, view, validate, edit, beautify, and lint JSON — all running locally in your browser.

Turn raw or minified JSON into a clean, validated, syntax-highlighted document the moment you paste.

Render any payload as a navigable tree — fold deep nodes, search anywhere, copy by JSON path.

Catch syntax errors with line numbers and broken-fragment previews — before the document reaches your code.

Add indentation, syntax colors, and fold controls to ugly minified JSON — readable in a single click.

A full code editor for JSON — syntax highlighting, search, fold, copy-by-path, and live validation.

Strict RFC 8259 linter that flags every pitfall — trailing commas, single quotes, unquoted keys — with line precision.
