Frequently Asked Questions

Is my JSON data sent to a server?

No, all formatting and validation runs strictly on your device using JavaScript. Your data remains 100% private.

Can it fix invalid JSON?

The tool will attempt to format it, but if the JSON is structurally invalid (like a missing bracket), it will point out the syntax error so you can fix it.

What is JSON minification?

Minification removes all unnecessary whitespace, line breaks, and indentation from the JSON string to reduce its file size.
