JSON Formatter

Minified JSON — a single unbroken line of an API response or config file — is common but painful to read without tooling. JSON Formatter takes whatever JSON text you paste into the chat and returns it pretty-printed with indentation, which is often faster than pasting it into a browser extension or a code editor just to check a field.

It is a narrowly scoped utility with no other advertised feature: no validation report, no schema checking, just formatting. That keeps it fast and predictable for the one job it does, and it costs nothing to keep it bookmarked for the next time a webhook payload or API response needs a quick read.

Because its own profile has no bio describing exact limits, treat very large payloads with some caution and prefer a local tool for anything containing sensitive data you would not want to paste into any third-party bot.

FAQ

Does it validate my JSON or just format it?

Based on its name and behaviour it focuses on formatting; treat any validation as a side effect, not a guarantee.
