JSON (JavaScript Object Notation) is a lightweight data format used for storing and transporting data. It's easy for humans to read and write, and easy for machines to parse and generate.
Format (beautify) adds indentation and line breaks to make JSON readable. Minify removes all unnecessary whitespace to reduce file size, which is useful for production environments.
