Frequently Asked Questions

Find Quick Answers

What is FXML?

FXML is an XML-based markup language used in JavaFX to define user interfaces, allowing separation of UI structure from application logic.

Does this tool send my FXML files to a server?

No, all processing is done entirely in your browser using JavaScript. Your files and data never leave your device.

What file formats are supported?

The tool supports .fxml files (which are XML files) and any valid XML content. You can also paste XML directly into the textarea.

Can I view large FXML files?

Yes, but very large files may impact browser performance. The tool handles typical FXML files used in JavaFX applications efficiently.
