Overview
JSON to XML Converter — Convert JSON Online
Convert JSON into XML for SOAP services, legacy enterprise systems, and XML-based configuration formats. Paste a JSON object and get well-formed XML with elements derived from your keys and arrays expanded into repeated tags. When you have to integrate a modern JSON API with a system that only speaks XML, this bridges the gap — and it runs entirely in your browser.
How keys become elements
Each JSON key becomes an XML element, and its value becomes the element's text or nested content. Nested objects produce nested elements, preserving hierarchy. Arrays expand into repeated elements with the same tag name, which is the idiomatic way XML represents lists.
The output is well-formed XML you can drop into a SOAP envelope, a config file, or any consumer that expects an XML document instead of JSON.
When you need JSON to XML
- Calling SOAP or other XML-based web services from JSON data
- Feeding legacy enterprise systems that require XML input
- Producing XML configuration from a JSON source of truth
- Generating XML payloads for older integrations and partners
Round-tripping and naming rules
XML element names are stricter than JSON keys — they cannot contain spaces and cannot begin with a digit. Keep this in mind if your JSON keys are unusual. To convert in the other direction, the XML to JSON tool parses XML back into structured JSON, completing the bridge between the two formats.
FAQ
Frequently asked questions
How are arrays converted?
Array items expand into repeated XML elements sharing the same tag name, which is how XML idiomatically represents a list of values.
What happens to keys that are invalid XML names?
XML element names cannot contain spaces or start with a digit. Keys that violate these rules should be renamed in the JSON first to produce valid XML.
Does it add an XML declaration?
The tool produces a well-formed XML body. Add an <?xml version="1.0"?> prolog at the top if your consumer requires one.
Is my JSON sent to a server?
No. Conversion happens entirely in your browser, so your data stays on your device.
