How to format JSON online

  1. Paste raw JSON into the input box.
  2. Click Format to pretty-print, Minify to compress, or Validate to check syntax only.
  3. Copy the result for APIs, configs, or logs.

Why use a client-side JSON beautifier?

JSON payloads often contain tokens, PII, or internal IDs. A browser-only formatter keeps that data on your machine while still giving you fast pretty-print and minify tools.

Common JSON errors

  • Trailing commas after the last property
  • Single quotes instead of double quotes
  • Unescaped newlines inside strings
  • Comments (not allowed in strict JSON)
