Format, validate and minify XML
XML still powers SOAP, SVG fragments, RSS feeds, Android resources, and enterprise configs. Minified or single-line XML is painful to review. Formatting exposes hierarchy, namespaces, and attribute clusters so mistakes become obvious.

XML still powers SOAP, SVG fragments, RSS feeds, Android resources, and enterprise configs. Minified or single-line XML is painful to review. Formatting exposes hierarchy, namespaces, and attribute clusters so mistakes become obvious.
Use this when diffing SAML metadata, cleaning SOAP samples, or teaching students how element trees relate to schemas.
Validation is a separate step from formatting — a pretty document can still be invalid against an XSD.
An integration partner emails a SAML metadata XML blob. Formatting reveals duplicated `EntityDescriptor` blocks and a wrong certificate ordering before the file is trusted in production.
Structure visibility prevents shipping the wrong identity provider configuration.
Preserve namespaces and prefix declarations; reformatting must not drop `xmlns` attributes.
Large documents can be slow in-browser — trim to the subtree under investigation when possible.
Combine with schema validation or digital signature verification for production trust.
It should not change meaning, but always validate if the consumer is strict about whitespace in text nodes.
Different syntax; choose the tool matching your document type.
Formatted trees make XPath and element navigation easier visually.
Feeds are XML — formatting helps debug bad enclosures or namespaces.
Some pipelines minify for transport; humans prefer formatted source in repos.
Production parsers must disable dangerous external entity resolution; use this page only for trusted snippets.
Longer explanations that complement this calculator—same privacy-first, editorial tone.
A practical workflow for developers who want readable JSON and fewer “paste into random websites” mistakes.
A straightforward overview of client-side tools, optional Google ads, and how that maps to everyday privacy expectations.
Many teams choose between YAML and XML configs — validate each format appropriately.
