Introduzione allo strumento

Pretty-print JSON with consistent two-space indentation, right in your browser. Useful for inspecting API responses, log payloads, or untangling minified JSON before committing it to a fixture.

Panoramica dello strumento

JSON (JavaScript Object Notation) is a lightweight data format used by most web APIs. Minified JSON saves bytes on the wire but is hard to read by humans. The JSON Formatter parses your input with a strict JSON parser and re-emits it with two-space indentation and one key per line, so the structure becomes scannable. Nothing leaves your browser — formatting happens entirely on the client.

Casi d'uso

FAQ

Is my JSON sent to a server?+

No. Formatting runs entirely in your browser using the built-in JSON parser.

Why does it say "Invalid JSON"?+

Your input could not be parsed by the strict JSON spec. Common causes: trailing commas, single quotes instead of double, comments, or missing closing brackets.

Can I change the indentation level?+

Not yet. The output uses two spaces per level, which matches the most common style guides.
