도구 소개

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.

도구 개요

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.

사용 사례

  • Use JSON Formatter when you need fast format and beautify json with proper indentation.
  • Handle developer workflows directly in the browser with no install required.
  • Support SEO long-tail intent by covering quick checks, troubleshooting, and one-off conversions.

자주 묻는 질문

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.
