What is a JSON Beautifier?

A JSON beautifier formats raw or minified JSON so it's easy to read. Paste JSON from an API response, config file, or log—then view it as a collapsible tree. You can expand or collapse objects and arrays to focus on the parts you need.

How to use this JSON formatter

Paste your JSON in the input box, choose 2 or 4 space indentation, and click Beautify. The output appears as a tree on the right. Use the arrows to collapse or expand objects and arrays; use the full-screen icon to maximize either panel. All processing happens in your browser—nothing is sent to a server.
