JSON (JavaScript Object Notation) is a lightweight, text-based data interchange format that has become the de facto standard for web APIs and configuration files. This JSON editor provides a powerful environment for creating, editing, and validating JSON data with features like syntax highlighting, real-time validation, and formatting tools.
JSON is built on two fundamental structures: Objects (key-value pairs enclosed in curly braces {}) and Arrays (ordered lists enclosed in square brackets []). Values can be strings, numbers, booleans, null, objects, or arrays, allowing for nested data structures of arbitrary complexity.
