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.

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.
