Frequently Asked Questions
Can this tool validate XML?
Yes. The tool parses your XML using the browser's DOMParser API and automatically detects structural errors. If parsing fails, it displays an error message along with line and column information when available.
What indentation options are supported?
You can format XML using 2 spaces, 4 spaces, or tab indentation. You can switch between options instantly.
Is my XML uploaded to a server?
No. All formatting, validation, and minification are performed entirely in your browser. Your XML content is never transmitted or stored.
