Sobre JSON para XML

O Conversor JSON para XML transforma dados JSON em marcação XML bem formada instantaneamente no seu navegador. Chaves de objeto JSON tornam-se nomes de elementos XML, valores tornam-se conteúdo de texto do elemento.

Principais recursos de JSON para XML

  • Convert JSON objects and arrays to well-formed XML elements
  • JSON keys become XML element tag names
  • Arrays are expanded into repeated sibling elements
  • Formatted XML output with proper indentation
  • Handles nested objects and mixed-type arrays
  • Works entirely in-browser — no server uploads
  • One-click copy or download of XML output
  • Validates JSON input before converting

Formatos suportados

Formatos de entrada

Objetos JSONArrays JSONEstruturas JSON aninhadas

Formatos de saída

XML bem formado com indentação adequada

Nomes de elementos XML devem ser identificadores válidos. Chaves JSON que começam com números serão sanitizadas.

Exemplos

Convert a user object to XML

Transform a JSON API response into XML for use with a legacy SOAP service.

Entrada

{"user":{"id":1,"name":"Alice","active":true}}

Saída

<user>
  <id>1</id>
  <name>Alice</name>
  <active>true</active>
</user>

Convert a JSON array to repeated XML elements

Represent a list of items as sibling XML elements.

Entrada

{"items":["apple","banana","cherry"]}

Saída

<items>
  <item>apple</item>
  <item>banana</item>
  <item>cherry</item>
</items>

Casos de uso comuns

  • Preparing JSON API responses for submission to SOAP-based web services
  • Converting JSON configuration data to XML for enterprise middleware
  • Bridging modern REST API output with legacy XML-consuming systems
  • Generating XML data fixtures for testing XML parsers and validators
  • Converting JSON exports to XML for import into CMS or ERP systems
  • Producing XML from JSON for RSS or Atom feed generation workflows

Solução de problemas

Invalid XML element name from a numeric JSON key

Solução

XML element names cannot start with a number. JSON keys like "123" will be wrapped in a generic element name. Rename your JSON keys to start with a letter before converting.

Array items appear with generic item element names

Solução

JSON arrays are mapped to repeated elements with a generated name (e.g., <item>). This is the standard approach since arrays have no key names. Rename the array key in your JSON to control the parent element name.

Conversion fails with a JSON syntax error

Solução

Validate your JSON first using the JSON Validator tool. Common issues include trailing commas, single-quoted strings, or missing closing brackets.

Perguntas frequentes

Is the conversion lossless?

JSON to XML conversion preserves all values and the document structure. However, JSON arrays use generated element names and JSON type information (string vs number) is not retained in XML, which represents all content as text.

Can I convert XML back to JSON?

Use the XML Formatter tool which includes a Convert to JSON feature. For bidirectional workflows, maintain one format as the source of truth and convert as needed.

What happens to JSON null values?

JSON null values are converted to empty XML elements (e.g., <field/>). The semantics of null are lost in XML since XML does not have a native null type.

How are JSON arrays handled in XML?

JSON arrays become repeated sibling XML elements. For example, ["a","b"] under a key "items" produces <item>a</item><item>b</item> inside an <items> parent.

Can I specify a root element name?

The root element name comes from the top-level JSON key. Wrap your JSON in an outer object with the desired root name, for example {"myRoot": {...}} to get <myRoot>...</myRoot>.

Does the output include an XML declaration?

The tool produces the XML element tree. You can prepend <?xml version="1.0" encoding="UTF-8"?> manually if your target system requires it.

Is my data sent to a server?

No. All conversion is performed locally in your browser. Your JSON data never leaves your device and is not transmitted or stored.

What if my JSON key contains spaces or special characters?

XML element names cannot contain spaces or most special characters. The converter will sanitize or skip invalid characters. Rename your JSON keys to use letters, numbers, hyphens, or underscores only.
