Your API returns JSON but the legacy system you are integrating with only accepts XML. Or you need to generate an XML feed from JSON data. JSON-to-XML conversion has edge cases that trip up most converters.
Conversion Challenges
| JSON Feature | XML Challenge | How We Handle It |
|---|---|---|
| Arrays | XML has no native array type | Repeated elements with same tag name |
| Null values | No standard null representation | Empty element or xsi:nil="true" |
| Numeric keys | XML tags cannot start with numbers | Prefix with underscore: _123 |
| Special characters in keys | XML tags have strict naming rules | Sanitize to valid XML names |
| Mixed content | Text + child elements | Wrap text in CDATA if needed |
| Root element | XML requires single root | Auto-wrap in <root> element |
Output Options
- Pretty print. Indented, readable XML with line breaks.
- Minified. Compact XML for API payloads.
- With declaration. Include
<?xml version="1.0"?>header. - Custom root element. Name the root element instead of default <root>.

According to W3C XML specification, XML element names must start with a letter or underscore and cannot contain spaces.
As json.org documents, JSON and XML serve similar purposes but have fundamentally different data models.
