JSON to XML

Get more from JSON to XML

JSON to XML converts JSON to XML. The converter expresses object-shaped data through XML elements and, depending on the mapping, attributes or text nodes. XML attributes, namespaces, mixed text, and repeated elements do not have one universal JSON mapping. Agree on a convention with the receiving system. Inspect repeated values and names that are not valid XML element names before using the result. Use the worked example to understand what a successful result looks like, then compare it with a small sample of your own input. Keep the original available until you have checked the output in its destination. Conversion establishes a representation; it does not establish that the underlying information is correct or that the receiving application accepts every supported feature.

How to use this tool

1. Enter or load JSON using the input controls. Begin with the worked example or a small sample for which you know the expected result.
2. Review any available conversion options, then inspect the XML result. Resolve a reported parse error at its source before attempting to reuse the output.
3. Check the example below against your own data. Inspect repeated values and names that are not valid XML element names before using the result.
4. Copy or save the resulting XML content using the controls provided, then validate it in the application or parser that will actually consume it.

SEE IT IN PRACTICE

A worked example

{"person":{"name":"Ada"}}

<person><name>Ada</name></person> (mapping illustration)

The nested name property becomes a child element under person. Root naming and array representation depend on conversion options.

Arrays and root names

A JSON array has ordered items, while XML uses elements with names. The mapping needs to decide how each item is named and what element contains the collection. A top-level JSON value may also need a chosen document root. Compare the generated XML with a sample accepted by the receiving service; a plausible root name selected by a converter is not a substitute for the service’s expected structure.

Agree on element and attribute mapping

There is no universal rule saying which JSON properties should become XML attributes, child elements, or text. A simple nested object is easy to demonstrate, but repeated items and mixed content require a convention. Match the receiver’s expected root element, namespaces, and array representation. A well-formed XML document can still be the wrong document for a service if its element names and structure do not match the contract.

When this tool is useful

• Prepare XML examples from JSON data while retaining a separate copy of the source.
• Use a small example to troubleshoot element and array mapping and identify a representation mismatch.
• Create data-exchange prototypes without manually rewriting every field or symbol.

Tips for a better result

• XML attributes, namespaces, mixed text, and repeated elements do not have one universal JSON mapping. Agree on a convention with the receiving system.
• Inspect repeated values and names that are not valid XML element names before using the result.
• After changing formats, compare meaningful values rather than whitespace alone. Read the XML output with its intended parser when exact types or escaping matter.
