¿Qué hace XML Formatter and Converter?
XML Formatter and Converter permite formatear y validar datos directamente en el navegador y explica con claridad el resultado y sus límites. Capacidades verificadas: XML formatting, XML validation, XML minification, XML and JSON conversion.
Formatting preserves meaning better than cross-format conversion
Use Format XML or Minify XML when XML remains the authoritative format. Use XML and JSON conversion for integration work where the chosen attribute and text-node representation is understood and exact lexical preservation is not required.
¿Cómo se utiliza?
- Choose Format XML, Minify XML, XML to JSON, or JSON to XML.
- Paste one complete document into Input and select Convert.
- Review the validated output, then copy or download it without uploading the source document.

Errores frecuentes y soluciones
| Síntoma | Causa probable | Solución |
|---|---|---|
| The tool reports an invalid closing tag. | An element is missing its closing tag or the tag names do not match exactly. | Balance every start and end tag, including letter case, then run the conversion again. |
| A JSON round trip changes the shape of an element. | XML attributes, text nodes, repeated elements, and namespaces do not map one-to-one to ordinary JSON objects. | Use the generated JSON as an explicit representation and review @_ attribute keys and #text values before relying on a round trip. |
Important behavior of XML Formatter
Límite específico de esta herramienta: XML and JSON have different data models, so namespaces, comments, mixed content, and repeated elements may not round-trip exactly.

XML Formatter — FAQ
Does the XML Formatter upload my input?
No. Processing runs in the current browser tab, and the page does not send tool input to a KitLumi processing endpoint.
What input does the XML Formatter accept?
It accepts one well-formed XML document or a JSON object for JSON to XML mode. The workspace checks the input and reports malformed or unsupported values before it produces a result.
What does the XML Formatter produce?
It produces formatted or minified XML, or two-space-indented JSON. Copy and download controls appear when the output format supports them.
What limitation should I know?
XML and JSON have different data models, so namespaces, comments, mixed content, and repeated elements may not round-trip exactly.
