How to use JSON to XML
XML models elements and attributes differently from JSON objects and arrays. This converter builds a well-formed XML document from nested JSON and repeats elements for array members.
The generated structure is suitable as a starting point for feeds and legacy integrations, but the receiving system may require a particular root element, namespaces or attribute conventions.
A reliable workflow
- Paste valid JSON with a clear root object
- Convert and inspect repeated array elements
- Add any required namespaces, attributes or schema-specific wrapper elements
Worked example
Convert the included catalog containing two products
{"catalog":{"product":[{"id":1,"name":"Keyboard"},{"id":2,"name":"Mouse"}]}}The catalog becomes the document root and the product array becomes repeated product elements. A receiving API may still require namespaces or an attribute convention
When this tool helps
- Prototype a legacy API payload
- Create readable XML from internal JSON data
- Compare tree structure during a format migration
Accuracy and safety notes
- JSON keys must be valid or transformable XML element names for the target system
- XML schemas, namespaces and mixed text content require manual domain-specific work
Frequently asked questions
Does XXF upload or store my data?+
No. The conversion runs locally in your browser. Your input is not sent to XXF, stored on a server or used for training.
How are arrays represented in XML?+
Repeated array values are emitted as repeated elements under their JSON property name.
