About this tool
XML is still what many enterprise systems, SOAP services, and document formats expect. Converting JSON to XML means resolving a structural mismatch: JSON has arrays and a real null, XML has neither.
Arrays repeat the parent tag once per element, nulls become an element carrying xsi:nil="true", and any key that is not a legal element name is sanitised. A root-level array is wrapped in <item> elements, because a document with several top-level elements is not well-formed XML.
- Why is my array not visible as an array?
- XML has no array type. A list of three items becomes the same element three times over, which is the conventional encoding — but it does mean a one-element array and a plain value look identical in the output.
- What happens to a key like "first name" or "2fa"?
- Element names cannot contain spaces or start with a digit, so those are rewritten to something legal. The conversion is not reversible for such keys, which is worth knowing before using this as a storage format.
