A practical rule for webhooks, students, and tired Slack pastes.
JSON Formatter is for structure: missing commas, nested keys, a webhook that arrived as one line. It is a terrible place for a production private key. Paste a redacted sample. If the payload has customer phones, use a dummy.
Invalid JSON will not pretty-print. That is useful. Fix smart quotes from Word, trailing commas, and comments (standard JSON has none), then format again. Minify only when an API wants a compact body.
Students: this is how you learn to see objects. Professionals: this is how you avoid dumping secrets into a random website. Clear the box when you stand up from a shared computer. For real apps, keep using your editor — 1CLIK is the emergency lens, not the IDE.
