Format, validate, and beautify JSON data instantly. Free online tool for developers.
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. It's based on a subset of JavaScript but is language-independent.
JSON is commonly used for transmitting data between a server and web application, storing configuration data, and as a data format for APIs and web services.
JSON is easy to read and understand, making it perfect for configuration files and debugging.
Works with any programming language, not just JavaScript. Most languages have JSON libraries.
Supports nested objects and arrays, making it ideal for complex data structures.
Widely supported by web browsers and used as the standard format for REST APIs.
REST APIs use JSON to send and receive data between client and server applications.
Store application settings, user preferences, and configuration data in JSON format.
NoSQL databases like MongoDB use JSON-like documents for storing data.
Mobile applications use JSON for data synchronization and API communication.
JSON is more lightweight, easier to parse, and more human-readable than XML. JSON is also more commonly used in modern web development and APIs.
JSON can only store text data. Binary data needs to be encoded (e.g., using Base64) before it can be stored in JSON.
Yes, JSON is case-sensitive. Property names and string values must match exactly, including uppercase and lowercase letters.
JSON supports: strings, numbers, booleans, null, objects, and arrays. It doesn't support undefined, functions, or dates (these must be converted to strings).
