Frequently Asked Questions
- What XML features does this formatter support?
- The formatter handles elements with attributes, namespaces, self-closing tags, CDATA sections, comments, processing instructions (like <?xml?>), and mixed content. It preserves CDATA content verbatim and maintains attribute order.
- Does this validate my XML?
- It checks for well-formedness — matching open/close tags, proper nesting, and valid syntax. It does not validate against an XSD or DTD schema. If your XML has structural errors, the formatter will report the issue.
- Is this tool free to use?
- Yes. This tool runs entirely in your browser with no account required. Your data never leaves your device.
- Can I use this for SOAP or SVG files?
- Yes. SOAP envelopes and SVG images are both valid XML. The formatter handles namespaced elements and attributes correctly, making it suitable for debugging web service payloads or cleaning up SVG markup.
- Does this work on mobile?
- Yes. The tool is fully responsive and works on any device with a modern browser. You can paste XML from other apps, format it, and copy the result.
