XML to JSON Converter — Turn XML Into JSON

This XML to JSON converter parses XML documents and emits pretty-printed JSON, fully in your browser. Useful when moving data out of legacy systems — SOAP responses, RSS feeds, sitemap files, configuration files — into a modern JSON-based workflow.

XML still shows up everywhere — RSS feeds, SOAP APIs, sitemap.xml files, old SAML responses, financial data formats, government data dumps, and most legacy enterprise APIs. JSON is what modern tools, JS code, and LLMs prefer. Converting between the two is something people have to do all the time, and writing the mapping by hand is error-prone.

The tool uses fast-xml-parser, a battle-tested XML parser. Attributes are prefixed with `@_` to distinguish them from child element text, repeated child elements collapse into JSON arrays, and CDATA sections are preserved as plain strings. Conversion is entirely local — useful when the XML contains internal API payloads or proprietary data.

Output is JSON with two-space indentation. Drop it into a code editor, post it to an API, paste into an LLM prompt, or feed it into a script.
