A JSON formatter (or beautifier) takes minified, compressed, or disorganized JSON data and restructures it with proper spacing, indentation, and line breaks so that it is easy for humans to read.

Yes, absolutely. All processing is done securely within your browser using client-side JavaScript. Your JSON data is never transmitted to, or stored on, our servers.
