XML Formatter
Indent XML and surface well-formedness errors.
Loading tool
Paste a SOAP body or an SVG and indent it. External entities are not loaded.
How to use this tool
- Paste the snippet. Drop JSON, code, or a token into the input. It is not sent to a server.
- Run the action. Format, decode, or generate. Parse errors stay on the page.
- Copy the output. Copy the result back into your editor or terminal.
Safety
The parser disables network and does not resolve external entities, so XXE-style payloads cannot reach a host from this page.
Frequently asked
Does it validate against an XSD?
No. It checks well-formed XML, not a schema.
Can I format HTML?
HTML is often not well-formed XML. Use this only for XHTML or true XML.
Are CDATA sections kept?
Yes, when the input is well-formed.
Will namespaces be rewritten?
Prefixes are preserved. The formatter does not invent new ones.
Is the document uploaded?
No.
