JSON (JavaScript Object Notation) is a lightweight, text-based format used to store and exchange data. It is made up of key-value pairs and is widely used by APIs, configuration files, and web applications.

What does a JSON formatter do?

A JSON formatter takes raw or compressed JSON text and re-indents it with consistent spacing and line breaks, making it easier to read, debug, and share.

How do I format JSON online?

Paste your JSON into the input box, click Format, and the beautified version appears instantly in the result box. No installation or account is required.

How can I validate JSON?

Click the Validate button after pasting your JSON. The tool checks the syntax using the browser's built-in parser and reports whether it is valid, including the line and position of any error.

What is JSON beautification?

JSON beautification, also called formatting, adds indentation and line breaks to compact or minified JSON so its structure is easy to read.

Yes. Clicking Minify removes all unnecessary whitespace and line breaks while keeping the JSON valid, producing the smallest possible output for production use.

Is my JSON data private?

Yes. All formatting, validation, and minifying happens locally in your browser using JavaScript. Your JSON is never uploaded to a server.

Can I download formatted JSON?

Yes. After formatting or minifying, click Download to save the result as a .json file directly to your device.
