Frequently Asked Questions
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’s widely used in web APIs, configuration files, and data storage.
Formatted (pretty-printed) JSON uses indentation and line breaks to make the structure clear and readable. This is especially helpful when debugging APIs, reviewing config files, or sharing data with others.
Minified JSON removes all unnecessary whitespace and formatting to reduce file size. This improves performance when transferring data over the network (e.g., in production APIs or web apps).
