JSON Formatter / Beautifier

What is a JSON Formatter?

A JSON formatter (also known as a JSON beautifier or JSON prettifier) is a tool that takes raw, compressed, or unreadable JSON data and reformats it with proper indentation and line breaks so developers can read and debug it easily.

JSON (JavaScript Object Notation) is the most widely used data format for APIs, configuration files, and data exchange between systems. When JSON is returned from an API or stored in a database, it is often minified — all on one line with no spaces. Our free online JSON formatter instantly makes it readable.

How to Use the JSON Formatter

1. Paste or type your JSON data into the left input box.
2. Select your preferred indentation level (2, 3, or 4 spaces).
3. Click Format — the beautified JSON appears instantly on the right.
4. Click Copy to Clipboard to copy the formatted result.
5. Use Print JSON Data to print a clean copy of your JSON.

If your JSON contains a syntax error, the tool will highlight the exact error so you can fix it immediately.
