What this converter does

Transforms parsed JSON into indented XML. Object keys become element names, array items become repeated elements, primitive values become text, and null becomes a self-closing element.

How to use it

Paste strict JSON and inspect the XML preview. A single-key object uses that key as the document root; every other top-level value is wrapped in a root element.

Escaping

Ampersands, angle brackets and quotes in values are escaped as XML entities, so text cannot accidentally open a tag or attribute.

Arrays

Each array member is emitted with the same tag name. This produces conventional repeated sibling elements rather than an extra item wrapper.

Element names

JSON keys used as tags must be valid XML names and cannot contain spaces or begin with a number. Invalid keys produce an error instead of silently changing data.

Limitations

JSON has no native attributes, namespaces, comments or mixed content, so this converter creates elements only. The resulting schema is a deterministic convention, not a universal mapping.

Privacy

The conversion is performed locally in the browser. Your JSON and XML output are not sent to a remote service.

Frequently Asked Questions

How are JSON arrays represented in XML?
Every array item becomes a repeated XML element using the JSON property name as its tag.
What happens when a JSON key is not a valid XML name?
The converter reports an error instead of renaming the key and silently changing the document structure.
Does this converter upload my JSON?
No. Parsing, XML escaping and rendering all happen locally inside your browser.
