About this conversion
Convert JSON to XML when you need to feed data into a legacy system, SOAP service, or any integration that requires XML. While JSON dominates modern APIs, plenty of enterprise systems and government/financial integrations still expect XML payloads.
When this conversion is useful
- Producing XML payloads for SOAP web services from JSON-based source data
- Generating XML feeds (RSS, Atom) from JSON-driven content
- Integrating with legacy ERP, banking, or government APIs that require XML
- Producing XML config files from JSON-driven build scripts
Quality and tradeoffs
JSON keys become XML element names. Strings become text content. Arrays become repeated elements with the same name. Nested objects nest as child elements. Attributes need explicit prefix conventions in the source JSON to round-trip cleanly.
Frequently asked questions
How are JSON arrays represented in XML?
As repeated elements with the same tag name. For example, `{ "items": ["a", "b"] }` becomes `<items>a</items><items>b</items>` (or an `<items>` wrapper around child elements, depending on convention).
Will my JSON keys be valid XML element names?
Mostly. JSON allows characters that aren't valid in XML element names (spaces, special characters, leading digits). The converter sanitises these — e.g., spaces become hyphens.
Do I get a schema or DOCTYPE in the output?
No — the output is well-formed XML without a schema declaration. If your target system needs an XSD or DTD, add the schema reference manually.
