About JSON

JSON (JavaScript Object Notation) is a lightweight, text-based data interchange format. It's easy for humans to read and write, and easy for machines to parse and generate.

Common Use Cases:

API responses and requests
Configuration files
Data storage and exchange
NoSQL database documents
Web application state management

💡 Pro Tip: Always validate JSON before using it in production. Invalid JSON can break applications and APIs.

Usage Examples

JavaScript

// Parse JSON string
const data = JSON.parse('{"name": "John", "age": 30}');

// Convert object to JSON
const jsonString = JSON.stringify(data, null, 2);

// Validate JSON
try {
  JSON.parse(jsonString);
  console.log('Valid JSON');
} catch (error) {
  console.log('Invalid JSON:', error.message);
}

  "data": [
