How to format and validate XML
- Paste XML into the input editor or upload an XML file.
- Check the validation status and correct any reported syntax error.
- Select Format to indent the document, or Minify to remove extra formatting whitespace.
- Copy the formatted XML or download it when you are finished.
Common XML formatting uses
Inspect SOAP or REST payloads, review application configuration, clean up sitemaps and RSS feeds, and make generated XML easier to share in documentation or code review.
XML validation tips
- Close every element and ensure opening and closing tag names match.
- Quote attribute values and escape reserved characters such as ampersands.
- Use one root element for a well-formed XML document.
XML Formatter FAQ
Can I validate XML here?
Yes. The tool checks XML syntax as you edit and reports invalid documents with an error message and location when available.
Does minifying XML change its data?
Minifying removes unnecessary formatting whitespace. Review XML that intentionally depends on text whitespace before using a minified result.
Is my XML sent to a server?
No. Formatting, validation, and minification run locally in your browser. DevKit does not upload or store your XML.
Can I use XML from APIs or configuration files?
Yes. It is useful for API payloads, application configuration, sitemaps, RSS feeds, and other XML documents.
What makes XML well-formed?
XML needs one root element, matching opening and closing tags, quoted attributes, and properly escaped reserved characters.
What is XML pretty printing?
Pretty printing adds indentation and line breaks so nested elements are easier for people to inspect without changing their structure.
Can I format XML with namespaces?
Yes. Namespace declarations are preserved as part of the XML document when it is formatted.
Why is an ampersand invalid in XML?
An ampersand begins an entity reference in XML. Write literal ampersands as & in text content.
