XML Formatter is now live on Tools.Town — a tool that takes minified or inconsistently formatted XML and outputs clean, properly indented, valid XML, with well-formedness validation and line-number error reporting.
Paste XML from an API, config file, or SOAP response — and get readable, validated code in one click.
What Does It Do?
Beautify
Adds consistent indentation and line breaks to any XML — choose 2-space, 4-space, or tab indentation.
Validate
Checks XML well-formedness — mismatched tags, unclosed elements, and bad attributes are flagged with line numbers.
Minify
Strip all whitespace and compress the XML for production payloads, SOAP requests, or compact storage.
The formatter checks well-formedness only (structural validity). Full XML Schema (XSD) validation is available in the advanced mode.
How It Works
Paste XML
Paste any XML — a single-line API response, a large config file, or a SOAP envelope.
Validate
Well-formedness errors are highlighted immediately with the exact line and element causing the problem.
Copy output
Copy the formatted (or minified) XML, ready to paste back into your code or API tool.
Why We Built It
XML from APIs, configuration systems, and SOAP services is frequently minified or inconsistently indented — unreadable without formatting. XML Formatter makes it readable instantly and catches structural errors that would otherwise surface as cryptic parser exceptions in your application.
