What is JSON?
JSON (JavaScript Object Notation) is a lightweight, text-based data interchange format. It is easy for humans to read and write and easy for machines to parse and generate. JSON is built on two structures: key-value pairs (objects) and ordered lists (arrays).
Despite its JavaScript origins, JSON is language-independent and supported by virtually every programming language, framework, and database. It has become the dominant format for web APIs, configuration files, and data storage.
Formatting (or "pretty-printing") adds indentation and line breaks to make JSON readable. Minifying removes all unnecessary whitespace to reduce file size for production. Validating checks whether a string is structurally valid JSON.
