JSON Viewer & JSON Formatter

Paste, view, and format JSON data with a clean, structured, and readable layout — similar to how JSON looks inside VS Code.

What can this JSON Viewer do?

• Format and beautify minified JSON
• Highlight keys, values, strings, and numbers like a code editor
• Explore nested objects and arrays visually
• Debug API responses faster

Example 1: Simple JSON Object

A basic JSON object returned from an authentication or profile API.

{
    "id": 1024,
    "username": "demo_user",
    "active": true
    }

Colors help distinguish keys, strings, and values instantly.

Example 2: Nested JSON Structure

Nested JSON becomes easier to understand with indentation and color cues.

{
  "orderId": "ORD-78452",
  "orderStatus": "paid",
  "customer": {
    "userId": "USR-1024",
    "username": "demo_user"
  },
  "payment": {
    "paymentId": "PAY-55891",
    "method": "credit_card",
    "status": "success",
    "currency": "USD",
    "amount": 149.99,
    "paidAt": "2026-01-10T14:22:45Z"
  },
  "items": [
    {
      "productId": "PRD-001",
      "name": "Wireless Keyboard",
      "quantity": 1,
      "unitPrice": 99.99
    },
    {
      "productId": "PRD-002",
      "name": "Wireless Mouse",
      "quantity": 1,
      "unitPrice": 50.00
    }
  ],
  "createdAt": "2026-01-10T14:20:10Z"
}

What is a JSON Formatter?

A JSON Formatter takes raw or minified JSON and converts it into a structured, indented format with syntax highlighting — similar to how JSON appears in modern code editors.

Why developers prefer colored JSON

• Faster visual scanning
• Clear separation of keys and values
• Reduced cognitive load
• Editor-like experience in the browser

A modern JSON viewer should feel familiar — just like working inside VS Code.
