A JSON formatter takes raw, hard-to-read JSON and pretty-prints it with consistent indentation, so you can actually see the structure of the data. It also works as a validator: if the input is not valid JSON, you get the exact parse error and where it happens instead of a silent failure.
Use it when you are debugging an API response, inspecting a config file, or preparing JSON for documentation. The Minify action does the opposite job, stripping whitespace to make payloads as small as possible.
