Raw JSON

Formatted JSON

13 lines · 20 words · 160 chars

{
  "name": "Alice",
  "age": 30,
  "skills": [
    "SQL",
    "Python",
    "JavaScript"
  ],
  "address": {
    "city": "New York",
    "country": "USA"
  }
}

How it works

Paste messy or minified JSON into the input pane. The formatter parses it and outputs properly indented, human-readable JSON.

Features

2-space indentation, proper escaping, and instant validation. Invalid JSON shows a clear error message.

Use cases

Debug API responses, format config files, or prepare JSON for documentation and code reviews.
