JSON Formatter vs JSON Validator vs JSON Minify

A JSON Formatter improves readability by organizing JSON with indentation and spacing. A JSON Validator checks whether the JSON follows the correct syntax, while JSON Minify removes unnecessary whitespace to reduce file size. Developers often use all three tools together throughout the development process.
