What can I do with the XML formatter?

You can format (pretty-print) XML with 2 or 4 spaces indentation, minify XML to reduce file size, and validate XML syntax to check for errors — all in your browser.

Does the tool validate my XML?

Yes, the tool uses the browser's built-in DOMParser to validate XML. If there are syntax errors, it will display a clear error message showing what went wrong.

Is there a file size limit?

Since all processing happens in your browser, there's no strict limit. However, very large XML files (over 10MB) may cause slower performance depending on your device.
