What JSON to XML Converter does

JSON to XML Converter parses one complete JSON value and places it beneath a user-chosen root element. Objects become nested elements, arrays become repeated item elements, primitives become text, and null becomes a self-closing element with nil set to true.

JSON property names that are not valid XML element names are represented with a property element and a name attribute. Text and attribute content are escaped so supplied angle brackets, ampersands, and quotes cannot break the generated XML.

How to use JSON to XML Converter

  1. Enter a valid XML root name that does not begin with xml.
  2. Paste and validate the complete JSON value to convert.
  3. Select Convert to XML and inspect arrays, nulls, property names, and escaped text.
  4. Download the XML and test its mapping against the destination's expected schema.

Important details

Array and null conventions

An array property encloses repeated item children. An empty array becomes an empty property element, while null is emitted with nil="true"; this is a local convention, not automatic XML Schema instance typing.

Name and depth safety

The root must be a basic valid XML name and cannot begin with xml. Nested conversion is capped at 100 levels to prevent runaway recursion in extreme documents.

Practical uses

  • Create a draft XML representation for a system with simple nested data.
  • Inspect how arrays and object properties could map to elements.
  • Prepare a conversion fixture before defining a formal integration mapping.

Privacy and limitations

JSON parsing and XML serialization run in the browser, and neither document is uploaded to PagesTools. The downloaded XML is stored wherever the browser saves files.

There is no universal JSON-to-XML mapping. Namespaces, attributes from ordinary properties, schemas, mixed content, type metadata, ordering contracts, and destination-specific array rules require a deliberate integration design.

Common questions

Frequently asked questions

How are JSON arrays represented in XML?

The array's property element contains one item child for each array entry. The converter does not infer a domain-specific singular element name.

What happens when a JSON key is not a valid XML name?

The converter uses a property element and stores the original key in an escaped name attribute, preserving the key without creating malformed markup.

Does nil="true" use the XML Schema instance namespace?

No. It is the converter's simple null marker and has no namespace prefix. A receiving schema may require a different convention such as xsi:nil and must be adapted separately.
