XML Formatter
The XML Formatter takes minified or single-line XML and reformats it with consistent, readable indentation, making it far easier to scan through nested elements and attributes. Developers use it to inspect API responses, config files, or SOAP payloads that arrive as one dense line of markup.
Formatting happens locally using your browser's own XML parser, so the document you paste in — even one containing internal or customer data — is never uploaded to a server.
How to Use the XML Formatter
- Open the XML Formatter tool.
- Paste your minified or single-line XML.
- Click Format to apply indentation.
- Copy the formatted XML.
Frequently Asked Questions
Will this validate whether my XML is well-formed?
Formatting relies on parsing the document, so malformed XML with mismatched or unclosed tags will typically fail to format correctly, which itself flags a structural problem.
Can I format XML containing sensitive data like an API response with tokens in it?
Yes — the formatting is done entirely in your browser, so nothing in the XML is sent to a server, making it fine for internal or sensitive payloads.
Does it preserve attribute order and CDATA sections?
Yes, attributes keep their original order and CDATA sections are preserved as-is, only the whitespace between elements is adjusted.
