What is JSON?
JSON (JavaScript Object Notation) is a lightweight, text-based data interchange format that's easy for humans to read and write. Despite its name suggesting a connection to JavaScript, JSON is language-independent and widely used across different programming languages and platforms for data exchange.
Why Use JSON?
- Human-readable: JSON's syntax is intuitive and easy to understand
- Lightweight: Minimal syntax reduces file size and parsing overhead
- Universal support: Supported by virtually all modern programming languages
- Web-friendly: Native support in web browsers and APIs
- Structured data: Supports nested objects and arrays for complex data representation
How to Use JSON
JSON consists of key-value pairs enclosed in curly braces. Here's a basic example:
{
"name": "John Doe",
"age": 30,
"city": "New York",
"hobbies": ["reading", "swimming", "coding"]
}How to Compare JSON Files on This Site

- Load from URLs: Enter URLs pointing to JSON files for automatic loading
- Click Compare: Press the "Compare" button to analyze differences
- Review results: Navigate through highlighted differences using the toolbar
- Understand difference types:
- Missing properties: Properties present in one file but not the other
- Type differences: Same property with different data types
- Value differences: Same property with different values
