## What is a JSON formatter?

A JSON formatter (also called a beautifier or pretty printer) takes minified JSON — the compact
payload an API returns — and indents it so a human can read it. It also validates the document:
if the syntax is wrong, you get the exact error instead of a silent failure.

## Why this one?

Formatting runs entirely in your browser: nothing you paste is sent to or stored on any server.
Paste an API response straight from DevTools, pick your indentation, and copy the readable result.
