Formatted Output

Quick guide

Paste compressed or minified JSON and instantly transform it into a structured, human-readable format. Proper indentation reveals nested objects, arrays, and relationships between fields.

Use formatted output during debugging, code reviews, and documentation writing. It helps detect missing fields, incorrect types, and structural inconsistencies faster.

Real example

Input:
{"user":{"id":7,"roles":["admin"]}}

Output:
{
  "user": {
    "id": 7,
    "roles": [
      "admin"
    ]
  }
}
