{
  "status": "success",
  "data": {
    "user": {
      "id": 123,
      "name": "John Doe",
      "email": "john@example.com"
    },
    "posts": [
      {
        "id": 1,
        "title": "Hello World"
      },
      {
        "id": 2,
        "title": "Second Post"
      }
    ]
  },
  "meta": {
    "total": 2,
    "page": 1
  }
}

How it works

Paste your JSON — it validates and formats automatically
Invalid JSON shows error details with line/column position
Choose 2 or 4 space indentation
Copy or download the formatted result

Code Examples

Here's how to achieve this in different programming languages:

1// Format JSON with 2-space indentation
2const input = `{"status":"success","data":{"user":{"id":123,"name":"John Doe","email":"john@example.com"},"posts":[{"id":1,"title":"Hello World"},{"id":2,"title":"Second Post"}]},"meta":{"total":2,"page":1}}`;
3const formatted = JSON.stringify(JSON.parse(input), null, 2);
4console.log(formatted);

6// Output:
7// {
8//   "status": "success",
9//   "data": {
10//     "user": {
11//       "id": 123,
12//       "name": "John Doe",
13//       "email": "john@example.com"
14//     },
15//     "posts": [
16//       {
17//         "id": 1,
18//         "title": "Hello World"
19//       },
20//       {
21//         "id": 2,
22//         "title": "Second Post"
23//       }
24//     ]
25//   },
26//   "meta": {
27//     "total": 2,
28//     "page": 1
29//   }
30// }
