Frequently Asked Questions
Is my XML data secure when using this editor?
Yes, absolutely. All XML processing happens directly in your browser using client-side JavaScript. Your XML data never leaves your computer and is not sent to any server, ensuring complete privacy and security. The only exception is when you explicitly use the "Share" feature to generate a shareable link.
Can I edit large XML files?
Yes, the editor can handle XML files of various sizes. However, performance may vary depending on your browser and device capabilities. For very large files (over 1MB), consider using the maximize mode for better performance. If you need to work with extremely large files, you might also want to format XML first to optimize the structure.
Does the editor support XML namespaces and attributes?
Yes, the editor fully supports XML namespaces, attributes, CDATA sections, processing instructions, and other XML features. It validates XML according to standard XML 1.0 and 1.1 specifications, ensuring compatibility with all XML-based technologies.
What happens if my XML has errors?
The editor will display detailed error messages in the validation panel, helping you identify and fix syntax errors, unclosed tags, or other XML issues quickly and easily. Error messages include helpful tips and suggestions to guide you toward a valid XML structure.
How does the sharing feature work?
When you click "Share", the editor generates a unique URL containing your XML data. This link can be shared with team members or collaborators. The shared data expires after a certain period for security. Recipients can view, edit, and download the XML using the same editor interface.
Can I use keyboard shortcuts in the editor?
Yes! The editor supports all standard text editing shortcuts including Ctrl+F for find, Ctrl+H for replace, Ctrl+Z for undo, Ctrl+Y for redo, and more. These shortcuts work the same way as your favorite code editors, making the transition seamless.
What XML file types are supported?
The editor supports all standard XML file types including .xml, .txt files containing XML, configuration files (web.config, app.config), Android manifest files, Maven POM files, Spring configuration files, SOAP messages, RSS feeds, and any other XML-based format. You can also convert XML to table for better visualization.
Is this XML editor completely free?
