Mapping rules
| JSON | XML |
|---|---|
{"title": "SEO"} | <title>SEO</title> |
{"@id": "1"} | attribute id="1" |
{"#text": "Hi"} | element text |
{"tag": ["a", "b"]} | <tag>a</tag><tag>b</tag> |
null | empty element <tag/> |
Special characters are escaped (&, <, >, quotes) and invalid element names are made safe, so the output is always well-formed. Top-level arrays are wrapped in the root element you choose.
Convert back with the XML to JSON Converter or tidy the result with the XML Formatter.

What happens to keys with spaces?
They are converted to valid XML names by replacing invalid characters with underscores.
Is an XML declaration added?
Yes, the output starts with .
