JSON to XML Converter
The JSON to XML Converter transforms JSON data into XML format. XML (eXtensible Markup Language) is used in SOAP APIs, legacy systems, configuration files, and enterprise applications. This converter handles JSON objects, arrays, and nested structures, converting them to well-formed XML with appropriate element names and attributes. It is useful for integrating modern JSON APIs with XML-based systems, migrating data, and working with enterprise software that requires XML input.
Formula
Conversion rules: - JSON object → XML element with child elements - JSON key → XML tag name - JSON value → XML text content - JSON array → repeated child elements - JSON attributes → XML attributes (with @ prefix) Root element wraps the entire structure
Example
Input JSON: {"user": {"name": "Alice", "age": 30}} Output XML: <?xml version="1.0" encoding="UTF-8"?> <root> <user> <name>Alice</name> <age>30</age> </user> </root>
How to Use
- Paste your JSON data into the input field
- Optionally set a custom root element name
- Click convert to generate XML
- Review the well-formed XML output
- Copy or download the XML for your use
Frequently Asked Questions
How are JSON arrays converted to XML?
JSON arrays become repeated XML elements with the same tag name. For example, ["apple", "banana"] becomes <item>apple</item><item>banana</item>. The tag name is derived from the JSON key or defaults to 'item'.
Can I convert JSON with special characters?
Yes, special XML characters like less-than, greater-than, and ampersand are automatically escaped to their entity references. This ensures the output is valid XML that can be parsed by any XML parser.
What root element is used?
By default, the converter wraps the JSON in a <root> element. You can customize the root element name. XML requires a single root element, so this wrapper is necessary for valid XML.
How are JSON null values handled?
JSON null values can be converted to empty XML elements (<tag></tag>) or omitted entirely. You can configure this behavior. Some systems prefer empty elements for schema consistency.
Is the output valid XML?
Yes, the output is well-formed XML that passes validation. It includes the XML declaration, proper escaping, and a single root element. You can validate it with any XML validator or parser.
