About the JSON Beautifier
A JSON beautifier and a JSON formatter do the same essential job: they take valid JSON and re-render it with human-friendly indentation. Beautifying is the first step in almost any debugging session, because a wall of single-line JSON is nearly impossible to reason about, while a nicely indented version reveals structure at a glance.
This beautifier parses your JSON and re-emits it with the indentation you choose, highlighting syntax along the way. Like all tools here, it runs entirely client-side for speed and privacy. If your input is not valid JSON, you will get a precise error pointing to the line and column that needs attention.
