What is JSON to XML Converter?

JSON to XML is a conversion tool that transforms JSON (JavaScript Object Notation) data into well-formed XML (Extensible Markup Language) documents. It handles all JSON data types: objects become XML elements, arrays use repeated child tags, strings and numbers become text content, booleans are preserved as-is, and null values produce self-closing tags. You can customize the root element name and download the result as an .xml file.

  3. 3

    Click Convert

    Press Convert or Ctrl+Enter to generate the XML output with proper indentation.

Frequently Asked Questions

How are JSON arrays handled in XML?+
Each array element becomes a child XML element. By default, array items use the tag name "item". If the array is a value of a named key, items use that key name.
What about JSON null values?+
Null values are converted to self-closing XML tags, e.g., <maintenance/> for {"maintenance": null}.
Are special characters escaped?+
Yes, all XML-reserved characters (&, <, >, double quotes, single quotes) are properly escaped in text content using XML entities.
Can I customize the root element?+
Yes, use the root element name input field. Only valid XML name characters (letters, numbers, underscore, dot, hyphen) are allowed.
How are nested objects handled?+
Nested JSON objects become nested XML elements. Each key becomes a child element, maintaining the full hierarchy with proper indentation.
What if my JSON keys contain invalid XML characters?+
Invalid characters in JSON keys are replaced with underscores to ensure valid XML tag names. Keys starting with numbers get a leading underscore.
Can I convert XML back to JSON?+
Yes, use our XML to JSON converter at /tools/xml-to-json for the reverse conversion.
Is there a size limit?+
No hard limit. The tool runs in your browser, so performance depends on your device. JSON files up to several megabytes should work fine.
