XML Formatter, Validator & Minifier
Pretty print, validate, and minify XML snippets for feeds, sitemap samples, API payloads, config files, and documentation with browser-side processing.
An XML formatter validates XML syntax and rewrites the document with readable indentation.
Use minify when you need compact XML after confirming the source is valid.
Use complete XML when possible
A root element and well-formed opening and closing tags make validation meaningful.
Keep schema checks separate
Syntax validation is useful, but product-specific XML rules still need schema-aware validators.
Try a common XML snippet
Needs attention
XML validation is loading in the browser.
XML formatting note
Formatting validates XML structure, but it does not verify business rules, schema definitions, signatures, or external references.
Formatting fragments as full documents
XML validation expects well-formed structure. A snippet without a single root may need wrapping before formatting.
Assuming syntax validates the schema
The browser parser checks well-formed XML, not XSD, DTD, namespaces, sitemap rules, or product-specific requirements.
Minifying before review
Minified XML is harder to inspect. Pretty print first, then minify only after the structure is correct.
Pretty print XML
Turn compact XML responses, feeds, and config snippets into readable indentation.
XML syntax checker
Catch malformed tags, missing roots, and parser errors before copying output.
XML minifier
Compact well-formed XML after reviewing the structure in formatted mode.
Sitemap XML review
Format sitemap samples before checking URL-level issues with the sitemap checker.
Suggested workflow
Structured text cleanup path
Validate structured text, compare changes, and check related sitemap or config output.
How is XML processed?
XML validation, formatting, and minifying are handled in the browser for this tool based on the current public implementation.
Can it validate XML syntax?
Yes. The tool uses the browser XML parser to detect malformed XML before output is copied.
Can it minify XML?
Yes. Valid XML can be converted to compact output by removing unnecessary whitespace between tags.
Does it validate XML schemas?
No. It checks XML syntax, not XSD, DTD, or product-specific schema rules.
