What a JSON formatter is for and when to use it
Why validating, formatting and minifying JSON helps with debugging, APIs and everyday development work.
Readability and debugging
Compact JSON is useful for transport, but often inconvenient to read. Pretty print makes the structure much easier to inspect.
When a payload is invalid, early validation prevents a long chain of downstream errors.
Minify and validation
Formatting alone is not enough. A good tool should also tell you whether the JSON is valid and provide a minified version when needed.
That makes it useful both for development and technical documentation.
