JSON Formatter & Validator

A JSON formatter takes raw, often unreadable JSON — like API responses or config exports — and reformats it with consistent indentation and line breaks so it's easy to read and debug. This tool also validates the JSON and can minify it back down for production use.

1. Paste or type your JSON into the input panel on the left.
2. Click Beautify JSON to pretty-print it with indentation, or Minify JSON to compress it to one line.
3. Click Validate at any time to check whether your JSON is syntactically correct.
4. Use Copy or Download to grab the formatted result.

Input:

{"name":"Acme","active":true,"tags":["a","b"]}

Beautified output:

{
  "name": "Acme",
  "active": true,
  "tags": [
    "a",
    "b"
  ]
}
