What is JSON to XML Converter?

Free online JSON to XML converter to convert any valid JSON object or array into well-formed XML with this free online tool.

Paste a JSON file or API response and get clean, indented XML you can copy or download. Configure the custom root element name, choose between nested elements or XML attributes for simple values, toggle the XML declaration, and adjust indentation. Handles nested objects, arrays (with smart singular-form element names), strings, numbers, booleans, and null values. Handy when feeding a SOAP service, an XML-based API, or a legacy system that expects XML instead of JSON. All XML special characters are properly escaped. Processing runs entirely in your browser - your data never leaves your device. No signup required.

How to Use JSON to XML Converter

1Paste your JSON data into the input area on the left
2Configure options: root element name, indentation, and XML declaration
3Click 'Convert' or press Ctrl+Enter to generate the XML
4Copy the XML output or download it as an .xml file

Frequently Asked Questions

How are JSON arrays converted to XML?

Each array item is wrapped in an element tag. The converter attempts to use the singular form of the parent key (e.g., 'users' becomes 'user'). If the singular form cannot be determined, 'item' is used as the default element name.

How are null values handled?

JSON null values are converted to self-closing XML tags. For example, { "middleName": null } becomes <middleName/>.

Does the converter escape special XML characters?

Yes. All five XML special characters are properly escaped: & becomes &, < becomes <, > becomes >, " becomes ", and ' becomes '. This ensures the output is always valid XML.

Can I customize the root element name?

Yes. By default the root element is named 'root', but you can change it to any valid XML element name using the Root Element input field.

Is my JSON data safe?

Absolutely. All processing happens locally in your browser using JavaScript. Your JSON data is never sent to any server, making this tool completely safe for sensitive or proprietary data.

When should I map JSON values to attributes instead of elements?

Use attributes for short, simple values like an id, a code, or a flag that describes the element, and use child elements for larger or nested content. Toggle the attribute option in the converter to render simple string and number values as XML attributes on the parent tag instead of separate nested elements.

Can I convert a JSON API response to XML for a SOAP service?

Yes. Paste the JSON response, set the root element to match what the SOAP or XML endpoint expects, and the converter wraps every key in a well-formed tag with escaped special characters. You may still need to add a namespace or envelope manually, since those are specific to each SOAP contract.

Does it keep the XML declaration at the top?

You control it. Toggle the XML declaration option to include or omit the leading <?xml version="1.0" encoding="UTF-8"?> line. Include it when the consuming system requires a standalone XML document, and omit it when the output will be embedded inside a larger XML payload.
