How are objects converted?

JSON keys become XML element names; values become element content. Root element defaults to ` ` — configurable.

What about JSON arrays?

Each array element becomes a repeated child element. `{items: [1, 2]}` → ` 1 2 `.

Opt-in — prefix JSON keys with `@` to mark them as XML attributes (`@id: "123"` → `id="123"`). Matches the common XML-JSON convention.

Limited. Add `xmlns:prefix` keys to the JSON; the tool propagates them to the root. Complex namespace-aware XML is better hand-written.

JSON and XML have been competing data formats since the mid-2000s, with JSON overtaking XML in API usage by 2013.
XML can represent data structures that JSON cannot, such as mixed content (text interleaved with elements) and attributes.
The XML specification is 33 pages long, while the JSON specification fits on a single printed page.

How are objects converted?: JSON keys become XML element names; values become element content. Root element defaults to `<root>` — configurable.
What about JSON arrays?: Each array element becomes a repeated child element. `{items: [1, 2]}` → `<items>1</items><items>2</items>`.
How are attributes generated?: Opt-in — prefix JSON keys with `@` to mark them as XML attributes (`@id: "123"` → `id="123"`). Matches the common XML-JSON convention.
Does it handle namespaces?: Limited. Add `xmlns:prefix` keys to the JSON; the tool propagates them to the root. Complex namespace-aware XML is better hand-written.
