Online JavaScript ⇄ JSON Converter – Free & Fast Tool for Developers

What is JSON ⇄ JavaScript Converter?

This tool allows seamless conversion between JSON objects and JavaScript objects. Ideal for developers handling data in APIs or needing to transform configuration files for client-side applications.

Here are examples demonstrating JSON to JavaScript and vice versa:

Example: Convert JSON to JavaScript

{
  "id": 1,
  "name": "Laptop",
  "price": 1200
}

Converted JavaScript output:

const data = {
  id: 1,
  name: "Laptop",
  price: 1200
};

Example: Convert JavaScript to JSON

const product = {
  id: 2,
  name: "Phone",
  price: 800
};

Converted JSON output:

{
  "id": 2,
  "name": "Phone",
  "price": 800
}

Syntax & Structure

• JSON keys become JavaScript object properties. const obj = { key: 'value' };
• Valid JSON must be properly quoted, unlike JavaScript objects. { 'key': 'value' }

Supported Elements

• Supports nested structures and arrays. const obj = { list: [1, 2, 3] };
• Maintains primitive types such as numbers, strings, and booleans. const obj = { active: true };

Practical Use Cases

Useful for converting API payloads, preparing mock data, or generating JavaScript variables from JSON data.
