What is JSON?

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. It supports objects, arrays, strings, numbers, booleans, and null values.

Formatting (pretty-printing) adds indentation to make JSON readable, while minifying removes all unnecessary whitespace for smaller payload sizes.
