JSON Formatter & Validator

What is JSON?

JSON (JavaScript Object Notation) is a lightweight, text-based data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It is widely used for transmitting structured data between client and server in web applications, APIs, mobile and desktop applications. JSON has become the de facto standard for data exchange in modern web development and is supported by virtually all programming languages and platforms.

Why Format and Validate JSON?

Properly formatted JSON improves readability, making it easier to debug, analyze, and maintain code. Minification reduces file size for faster network transmission and improved performance. Our intelligent auto-fix feature quickly corrects common syntax errors that occur during manual editing, copying from other sources, or when working with legacy data formats.
