Cómo funciona el XML Formatter

Esta herramienta procesa tu código XML (eXtensible Markup Language) directamente en tu navegador. Transforma largas cadenas incomprensibles de datos en un árbol visualmente estructurado con identaciones estandarizadas de 2 espacios. Si tu documento XML contiene errores de sintaxis u omisiones de cierre de etiquetas, el editor te alertará en tiempo real marcando el borde en rojo y detallando el error.

Además, gracias al motor subyacente de Monaco Editor (el mismo que usa Visual Studio Code), cuentas con capacidades de envoltura de palabras, resaltado de sintaxis preciso y desplazamiento ultra fluido, sin importar el peso del archivo.

Privacidad por Diseño (Local-First)

A diferencia de otros formateadores online que envían tu configuración a un servidor remoto, esta suite Dev/IT está construida con la directiva Local-First. Todo el análisis, minificación y formateo del XML ocurre estrictamente dentro del cliente (tu navegador) a través de JavaScript puro (usando xml-js). Ningún byte abandona tu dispositivo, garantizando que el uso con XMLs que contengan credenciales de integraciones o datos de producción sea 100% confidencial y seguro de usar en entornos corporativos.

What this tool does

XML is still common in enterprise APIs, feeds, integrations and configuration files. This page helps you format or validate XML locally so broken tags, nesting issues and copied payload problems are easier to spot.

Formats unstructured or minified XML into readable, consistently indented output so nested elements are easier to inspect.
Validates XML syntax and surfaces common errors such as unclosed tags, mismatched element names and malformed attributes.
Supports minification for cases where you need compact XML for transport or storage after editing a formatted version.

How to use it

1
Paste the XML content into the input editor.
2
Use Format to produce readable, indented output for review, documentation or code editing.
3
Use Validate to confirm the document is well-formed before using it in an integration or config pipeline.
4
Use Minify when you need compact output for transport, API payloads or embedded config.

Example

A developer receives a SOAP response as a single-line string and formats it to review the nested element structure before writing a parser for the relevant fields.

<response><status>ok</status><data><id>42</id><name>Example Corp</name></data></response>

<response>
  <status>ok</status>
  <data>
    <id>42</id>
    <name>Example Corp</name>
  </data>
</response>

Use cases

Reviewing SOAP or legacy API responses during debugging.
Cleaning up XML config files before editing or sharing them.
Validating copied XML snippets from logs, exports or documentation.

Common mistakes

Confusing well-formed with valid

Well-formed XML follows correct syntax rules. Valid XML also conforms to a specific schema or DTD. This tool checks well-formedness, not schema validity.

Pasting XML with namespace declarations stripped out

XML namespaces are part of the document structure. Removing them before pasting can cause false validation errors.

Editing formatted XML and forgetting to close new tags

XML is strict about tag closure. Every opened element must have a matching closing tag or be self-closed.

FAQ

What is the difference between formatting and validating XML?

Formatting improves readability by adding indentation. Validation checks whether the syntax is correct and the document is well-formed.

Can I use this for SOAP payloads?

Yes. SOAP envelopes are XML documents and benefit from formatting during debugging.

Does XML formatting change the data?

No. It only adjusts whitespace and indentation. Values, attributes and element names remain unchanged.

Is this tool useful for RSS or Atom feeds?

Yes. Both are XML-based formats and can be formatted and validated here.

Does this upload my XML data?

No. Processing happens locally in the browser.

Privacy and security

XML processing stays inside the browser.
No payload is uploaded for formatting or validation.
That is safer when the XML contains internal endpoints, identifiers or business data.
