XML ↔ JSON Converter
Convert between XML and JSON formats. Handles attributes, CDATA, arrays, and nested elements.
XML ↔ JSON Converter
Convert between XML and JSON formats bidirectionally. The XML parser handles attributes (mapped to @-prefixed keys), CDATA sections, comments, processing instructions, self-closing tags, repeated child elements as arrays, and namespace prefixes preserved in key names. JSON-to-XML reverses the convention so these constructs round-trip cleanly. Useful for SOAP-to-REST migration and legacy system integration. Drop an .xml or .json file or paste content directly; copy the output to clipboard or download it as a file. Runs entirely in your browser — your data never leaves your machine.

XML Is Still Everywhere You Do Not See It
JSON may dominate public-facing APIs, but XML is still the dominant format inside the enterprise. SOAP web services, XBRL financial filings, HL7 CDA clinical documents, OOXML (Office documents), SVG, RSS, XMPP, Android resource files, and the configuration layer of nearly every Java application are all XML. Modernizing or integrating those systems almost always means translating their XML payloads into JSON so they can be consumed by a REST/GraphQL frontend, a modern microservice, or a JSON-native event stream. Going the other direction is common too — legacy systems that expect SOAP still need JSON payloads from newer systems wrapped back into XML at the boundary.
The XML ↔ JSON Impedance Mismatch
XML has three concepts that JSON does not: attributes, element order, and mixed content (text interleaved with child elements). The most common convention — and the one this tool uses — is to emit attributes as properties prefixed with @, text content as #text, and repeated child elements as JSON arrays. CDATA sections, comments, and self-closing tags round-trip cleanly. This convention is lossy for order-dependent mixed content but correct for the vast majority of XML encountered in business integration work.
SOAP-to-REST and Legacy Integration
For related format work, the YAML ↔ JSON Converter handles configuration-focused conversions, and the XML Formatter is useful for pretty-printing and validating XML before conversion. If you are wrapping a SOAP service with a REST facade, migrating a legacy XML interchange format to a JSON API, or bridging EDI/XML document flows into modern event streams, the converter is just the first five minutes of the project. I build integration layers that handle the hard parts — WSDL parsing, namespace handling, schema validation, error translation, authentication, and idempotent retry logic — so your modern front-end can talk to legacy systems without knowing or caring that they speak XML.
