Converting JSON to Structured XML Documents

Complete guide on converting JSON payloads to XML with custom root elements, item tags, attributes, and XML declaration headers.

Bridging JSON and XML in Enterprise Workflows

While REST and GraphQL APIs rely on JSON, many enterprise architectures, banking payment gateways, SOAP web services, and RSS feeds require XML formatting. Converting JSON to XML requires building structured hierarchical XML trees with proper closing tags and attribute mappings.

XML Conversion Features:

  • Customizable Root & Item Tags: Define custom wrapper elements (e.g. <records> and <user>).
  • Attribute Prefixing: Keys prefixed with @ automatically serialize as element attributes.
  • XML Header Options: Generates standard <?xml version="1.0" encoding="UTF-8"?> declarations.

Frequently Asked Questions

How does JSON to XML handle arrays?

Arrays are mapped to repeated child elements under a parent tag or named item wrapper.

Are special XML characters escaped?

Yes. Ampersands (&), angle brackets (< >), and quotes are properly escaped to prevent XML parse errors.
