XML ↔ JSON Converter
Convert everyday XML documents into JSON trees and rebuild basic XML from a single-root JSON object. Useful for feeds, legacy APIs, and quick debugging — attributes map to @keys and processing stays local via DOMParser.
Runs entirely in your browser. Your data never leaves this device.

FAQ
Is this a full XML schema mapper?
No — it is a practical MVP for common element/attribute trees, not XSD-driven mapping.
Are attributes preserved?
Attributes become @attr keys in JSON. Text nodes use #text when mixed content appears.
Is parsing safe?
We use the browser DOMParser for XML. Huge or hostile documents may still stress the tab — keep inputs reasonable.
Can every JSON become XML?
Arrays and primitives are wrapped as elements; exotic JSON may need manual shaping first.
