📖 What is JSON to XML?

JSON to XML converts a JSON structure into well-formed XML. Objects become elements, arrays become repeated elements, and primitive values become text content. Use it when integrating with SOAP services, legacy systems that require XML, or when transforming API data for XML-based tools. Everything runs in your browser.

💡 Example

Input
{"user":{"name":"Alice","age":30}}
Output
<user> <name>Alice</name> <age>30</age> </user>

🛠️ Common Use Cases

  • Converting REST API JSON responses for SOAP service consumption
  • Preparing data for XML-based tools like XSLT transformers
  • Generating XML config files from JSON templates
  • Integrating modern JSON APIs with legacy XML-based systems
  • Creating XML test data from JSON fixtures

📝 How JSON Maps to XML

  • JSON objects → XML elements with child elements for each key
  • JSON arrays → repeated elements with the same tag name
  • JSON strings/numbers/booleans → text content inside elements
  • JSON null → empty element or xsi:nil attribute
  • The root JSON key becomes the root XML element

⚠️ Common Mistakes

  • No root element — XML requires a single root element. If your JSON has multiple top-level keys, they are wrapped in a root element.
  • Invalid element names — XML element names cannot start with numbers or contain spaces. Keys like "2nd_item" become invalid XML.
  • Attribute vs element — this converter maps everything to elements. If you need XML attributes, post-process the output.

❓ Frequently Asked Questions

Can JSON arrays be converted to XML?
Yes — array elements become repeated XML elements with the same tag name. The tag name is derived from the parent key.
Does it add an XML declaration?
The output includes a standard XML declaration (). You can remove it if not needed.
What about JSON keys with special characters?
Keys containing spaces or special characters may produce invalid XML element names. Rename such keys before converting.
