FAQ

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.

What is the difference between format and minify?

Format adds indentation and newlines for readability. Minify removes all unnecessary whitespace to reduce file size.
