XML Formatter
Format, validate and minify XML documents entirely in your browser.
XML documents, especially generated or minified ones, are often delivered as a single dense line with no indentation. This tool formats/pretty-prints XML for readability, validates that it's well-formed, and can also minify it back down to a compact form when file size matters more than readability.
Frequently asked questions
Well-formed means the XML follows basic structural rules - matching tags, proper nesting, valid attribute syntax. The validator flags issues like unclosed tags or malformed syntax so you can fix them.
No - formatting only adjusts whitespace and indentation for readability; the elements, attributes, and text content remain exactly the same.
This tool checks that the XML is well-formed (structurally valid XML), not that it conforms to a specific custom schema - schema-specific validation would need a dedicated XSD validator.
