JSON to XML Converter — Custom Root & Pretty Print
Convert JSON data to well-formatted XML with our free browser-based converter. Set a custom root element name, configure indentation, and get properly structured XML output.
Handles arrays, nested objects, and primitive types with clean XML element mapping. Converts gracefully without needing network calls.
The conversion has to make choices JSON does not, and this one makes them explicitly: array items become repeated child elements rather than a single element containing a list, keys that are not valid XML names are sanitised instead of silently dropped, and reserved characters in values are escaped rather than left to break the parser downstream. Set the root element name to whatever the receiving schema expects. Typical destinations are a SOAP endpoint, an RSS or sitemap feed, and legacy systems that were built before JSON existed and are not going to be rewritten.
How to use JSON to XML
- Enter your JSON payload in the input pane.
- Give it a custom root wrapper name if needed.
- Configure formatting space characters to fit your preferences.
- Click Convert and immediately copy your XML output.
Features
- Clean mapping — Effectively resolves arrays and nested objects to proper markup tags.
- Customizable root elements — Wraps everything in a designated overarching node.
- Output beautification — Auto-indents XML tags for structure visibility.
- JSON syntax validation — Error messages for invalid JSON input.
- Download as .xml file — Save the output directly.
- Privacy focused — Your data doesn't go to a cloud processor.
Frequently Asked Questions
Does it support nested JSON arrays?
Yes. Elements within arrays will be wrapped in repeated identical tags inferred from the overarching list key, maintaining semantic parity within XML hierarchies.
How do you represent null parameters?
Null JSON key-values are represented as empty, self-closing XML tags without body content.
Is conversion exact when going back and forth?
It depends on specific implementations of attributes vs elements in XML. Often transitioning back to XML creates raw tags rather than regenerating metadata attributes.
Why do I need XML if the API I use returns JSON?
Because plenty of systems on the other side of an integration have not moved. SOAP services, government and banking APIs, enterprise middleware, and older ERP systems still expect XML, and RSS, Atom, and XML sitemaps are XML by specification. Converting at the boundary is usually far cheaper than changing either end.
What happens to characters like & and < in my values?
They are escaped to &, <, and > so the output is well-formed. This is the most common reason a hand-built XML document fails to parse: an ampersand in a company name or a less-than sign in a description. The converter handles it rather than leaving you to find it in a parser error.
