Converting JSON to XML: When and Why You'd Need It
Published: July 10, 2025 · 5 min read
JSON dominates modern APIs, but XML is still widely used in enterprise systems, SOAP APIs, RSS feeds, and many legacy platforms. Understanding when and how to convert between them is a valuable skill.
Why would you convert JSON to XML?
- Integration with legacy enterprise systems that only accept XML.
- Generating RSS/Atom feeds from JSON data.
- Consuming SOAP APIs that require XML payloads.
- Some configuration formats (Maven, Android manifests) use XML.
Structural differences
| Aspect | JSON | XML |
|---|---|---|
| Attributes vs Properties | Key-value only | Attributes + elements |
| Arrays | Native | Repeated elements |
| Root element | Optional | Required |
| Readability | Compact | Verbose but self-documenting |
Common conversion pitfalls
- JSON arrays don't have a direct XML equivalent — use repeated tags.
- Null values need special handling (empty element vs omitting).
- XML requires escaping special characters (&, <, >).
- XML tag names can't start with numbers.
