Represent JSON types explicitly when exporting XML
JSON to XML creates an explicit typed XML representation of JSON values. It is intended for transporting or inspecting JSON structure as XML, not matching an unrelated XML schema.
When should you use it?
- Provide an XML form of a JSON example.
- Inspect how nested JSON maps to elements.
- Round-trip data with this site’s XML-to-JSON mapping.
Example: a typed XML member
The member element records the property name, and the child element records that its value is a string.
{"name":"Alex"}<?xml version="1.0" encoding="UTF-8"?>
<object>
<member name="name">
<string>Alex</string>
</member>
</object>There is no single universal JSON-to-XML mapping
JSON names, arrays, null values, and scalar types do not have a universally agreed XML equivalent. This converter uses its own explicit typed mapping so the result can describe JSON values consistently. It does not infer the element structure required by a third-party XML API. A valid XML document can still be the wrong document for that API.
Match the target schema before integrating
If a system supplies an XSD or an example request, compare element names, attributes, namespaces, repeated elements, and empty values with that contract. A generic conversion is useful for inspecting or exchanging a representation of JSON, but an integration often needs a deliberate mapping. XML to JSON uses a separate element-oriented mapping, so the two tools are not a promise of a lossless round trip for arbitrary XML.
Map JSON to XML without guessing tag names.
JSON permits property names that are not valid XML element names. A typed mapping keeps those names in member attributes and represents values using predictable element names.
Load a JSON value
Objects, arrays, and scalar root values are supported.
Apply the typed mapping
Property names become name attributes; arrays use item elements.
Review and export
Download XML and adapt the mapping if the receiving system requires another schema.
How do I convert nested JSON to XML while keeping value types visible?
The exporter uses typed elements for objects, arrays, and scalars instead of guessing an application-specific XML schema. Object members carry their JSON property names in an attribute. This makes the output inspectable and suitable for this mapping, while other XML consumers may need a different shape.
XML shape for one JSON member
xml<object>
<member name="active">
<boolean>true</boolean>
</member>
</object>This is the element shape produced for {"active":true}; the actual document also includes an XML declaration.
Will this XML match my vendor’s schema?
Only if the vendor expects this exact typed mapping. The tool does not infer element names or attributes from an external XSD, so confirm the receiving contract first.
What should you check before using the result?
An external XML consumer may require a different element naming or schema. This tool does not infer that contract, so confirm compatibility before integration.
The mapping is explicit
An object becomes an object element containing member elements. Each member has a name attribute and a typed value child. Arrays contain item elements. null uses an empty null element. This preserves distinctions that a simple key-to-tag converter can lose.
XML compatibility
Ampersands, angle brackets, quotes, and whitespace characters are escaped where needed. XML 1.0 cannot represent every character allowed in JSON strings; unsupported characters cause an error instead of silent removal. The output does not claim to match an external application’s XML schema.
