Format, indent, and validate XML documents online for free. Also convert XML to JSON, no signup. Free XML formatter, validator, and beautifier tool.
Paste your XML at tools.arkaserve.com/xml-formatter and click "Format" — the tool adds proper indentation and line breaks with correct tag nesting instantly. Works on any XML: API responses, SOAP/WSDL, pom.xml, Android layouts, RSS feeds, SVG, or custom schemas. The formatted output is ready to copy back into your editor or IDE. Completely free, no signup.
Paste your XML and click "Validate" — the validator checks for well-formedness: all opened tags are properly closed, elements are correctly nested, attributes are properly quoted, special characters are correctly escaped (& for &, < for <), and the XML declaration is valid. Error messages include the line number and a description of the problem so you can fix it immediately.
Yes — after formatting, click "Convert to JSON" to transform your XML structure into an equivalent JSON object. XML elements become JSON keys, attributes are mapped with an "@" prefix, and text content maps to values. This is useful for modernizing XML-based APIs, integrating with JavaScript frontends that expect JSON, or migrating from SOAP/XML to REST/JSON services.
