This is a powerful, free online tool designed to format, validate, and minify JSON data instantly. Whether you are a developer debugging API responses or a data analyst handling configuration files, this JSON beautifier helps you visualize complex data structures clearly, correct syntax errors, and convert messy strings into readable code.

Yes, this is a key feature. Unlike strict JSON validators that reject keys without quotes, our tool intelligently parses JavaScript object literals and automatically converts them into valid, standard JSON format. This saves you time manually adding quotes to keys when copying code from JS files.

You can use the Minify feature. By clicking the Minify button, the tool removes all unnecessary whitespace, newlines, and indentation from your code. This creates a compact string that is perfect for reducing bandwidth usage during data transmission or saving storage space.

The Tree View offers an interactive way to navigate deep and complex data hierarchies. Instead of scrolling through thousands of lines of raw code, you can click to expand or collapse specific nodes. This makes it much easier to locate specific values and understand the structure of nested JSON objects.

Yes, your privacy is our priority. All formatting, validation, and processing happen entirely within your local browser. No data is sent to or stored on our servers, ensuring that your sensitive configuration files or API data remain private and secure.
