Pretty-print and validate XML with readable parser errors.
DOMParser validates XML locally after page load.

</tools>Paste XML to validate document structure, pretty-print nested tags with consistent indentation, or minify the result for compact storage and transport. Validation runs in the browser using DOMParser when available, so the document stays local.
XML is parsed with the browser's DOMParser and serialized with consistent indentation for nested elements. Parser feedback is generated locally so malformed tags can be corrected without sending the document to a server.
Example: A compact deployment configuration can be expanded into one element per line, making attributes, child nodes, and closing-tag mismatches easier to review.
Formatting does not validate a document against an XSD, DTD, namespace contract, or business rule. Browser XML parsing behavior can also differ from the server-side parser used by a particular integration.
No. Formatting and validation run locally in the browser after the page loads.
The tool uses the browser DOMParser where available, plus a lightweight structural check for clear tag mismatch errors.
Yes. Switch to Minify to remove formatting whitespace and copy or download the compact XML output.
