Formatting vs minification
Prettifying adds indentation and line breaks so humans can read the structure; minifying removes every non-essential space so machines transfer it faster. Both describe the same data — you switch between them depending on whether a person or a program is the audience.
Finding the error, not just the symptom
A single missing comma or stray quote invalidates an entire JSON document. Rather than telling you 'invalid JSON,' the formatter points at the precise location the parser choked on, which is usually a few characters before where you'd expect.
Local-first by design
API responses often contain tokens, emails, or personal data. Because everything is parsed in your browser, you can format production payloads without worrying that they're being logged on someone else's server.
