What is JSON?

JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It has become the de facto standard for data exchange in web APIs and modern applications.

Key Features of JSON

  • Language Independent: JSON is supported by virtually every programming language
  • Human Readable: Easy to understand and edit manually
  • Lightweight: Minimal syntax overhead compared to XML
  • Structured Data: Supports objects, arrays, strings, numbers, booleans, and null

Why Use a JSON Validator?

JSON validation is crucial for debugging API responses, configuration files, and data structures. Common JSON errors include missing commas, mismatched brackets, trailing commas, and invalid escape sequences. This tool helps you identify and fix these issues instantly, ensuring your JSON is properly formatted and ready to use in your applications.
