Frequently asked questions

What is JSON formatting?
JSON formatting (beautifying) adds proper indentation and line breaks to make compact JSON human-readable without changing any data.
What does minify do?
Minifying removes all whitespace and line breaks, reducing file size for use in APIs and production code.
Is my JSON data sent to a server?
No. All processing happens in your browser using JavaScript. Your data never leaves your device.
