Frequently Asked Questions

Is my JSON data secure?

Yes, all processing happens in your browser. We do not store or transmit your data to any server.

What does Minify do?

Minification removes unnecessary whitespace and newlines to reduce the file size, which is useful for specialized data transmission.

Can I validate invalid JSON?

Our tool highlights syntax errors to help you fix them, but you must correct the errors before the JSON can be properly formatted.
