JSON Viewer and Formatter

What is JSON?

JSON (JavaScript Object Notation) is a lightweight, text-based data interchange format that's easy for humans to read and write and easy for machines to parse and generate. Originally derived from JavaScript, JSON is language-independent and has become the de facto standard for data exchange in web applications and APIs.

Why Use a JSON Viewer?

A JSON Viewer is essential for developers, data analysts, and API testers who work with JSON data regularly. It provides several key benefits:

• Instantly validate JSON syntax and structure
• Visualize nested data hierarchies more clearly
• Debug API responses and configuration files
• Format messy or minified JSON into readable form
• Share formatted JSON with team members

Features

• Copy: Easily copy formatted or minified JSON to clipboard for sharing or use in your applications
• Format: Beautify JSON with proper indentation and spacing for improved readability
• Minify: Remove unnecessary whitespace to create compact JSON for production use
• Viewer: Interactive tree view with collapsible nodes for better visualization of complex structures
• Real-time Validation: Instant feedback on JSON syntax errors

Common JSON Data Types

• Objects: Collections of key-value pairs
• Arrays: Ordered lists of values
• Strings: Text enclosed in double quotes
• Numbers: Integer or floating-point
• Booleans: true or false
• null: Represents no value

Example JSON Structure

{
  "user": {
    "name": "John Doe",
    "age": 30,
    "isSubscribed": true,
    "preferences": {
      "theme": "dark",
      "notifications": true
    },
    "interests": ["programming", "data science", "web development"],
    "contact": {
      "email": "john@example.com",
      "phone": null
    }
  }
}

Best Practices

• Use clear, descriptive key names
• Maintain consistent naming conventions
• Keep nesting levels manageable
• Validate JSON before using in production
• Use appropriate data types for values
• Consider minifying JSON for production use

Common Use Cases

• API request and response payloads
• Configuration files
• Data storage and transfer
• Cross-origin resource sharing
• Web service integration
• Browser local storage
