How This Tool Converts JSON to XML
- Each JSON key becomes an XML element tag; the value becomes the element's text content or nested child elements.
- JSON arrays are expanded into repeated sibling elements sharing the same tag name —
["JS","Python"]under keyskillsbecomes two<skills>elements. - All output is wrapped in a
<root>element with an XML declaration header (<?xml version="1.0" encoding="UTF-8"?>). - To use a custom root tag name, wrap your JSON in an object with the desired key:
{"person": {...}}produces<person>...</person>inside root.
When to Use JSON to XML
- When integrating with a SOAP web service or legacy system that only accepts XML payloads.
- When generating RSS/Atom feeds or sitemap XML from a JSON data source.
- When a config system (Maven
pom.xml, Android manifest) requires XML and you are starting from a JSON template. - When exporting data to an XML-based reporting tool or BI platform.
Frequently Asked Questions
How does JSON to XML conversion work?
JSON objects become XML elements. Each key becomes an element tag and each value becomes the element's text content or nested child elements. Arrays are converted to repeated elements with the same tag name. All output is wrapped in a <root> element.
Can it convert nested JSON to XML?
Yes. Nested JSON objects become nested XML elements. Arrays of objects become repeated child elements, each containing the object's properties as sub-elements.
Is my data sent to a server?
No. All conversion happens entirely in your browser using JavaScript. Your data never leaves your device.
Can I control the root element name?
The tool wraps all output in a <root> element by default. To use a custom root name, wrap your JSON in an object with the desired key before converting: {"person": {...}} produces <person>...</person>.
Are XML namespaces supported?
No. This tool generates plain XML without namespace declarations. If your target system requires namespaces, add them manually to the output after converting.
