Overview: JSON ⇄ XML is a two-way converter that turns structured JSON objects into XML documents and parses XML back into JSON. Powered by fast-xml-parser, it supports attributes, nested elements, CDATA sections and complex namespace handling, covering most enterprise data-exchange scenarios.

How to use: Step 1 — enter or paste JSON in the left panel (you can also click the "Sample" button to load an example). Step 2 — the tool converts the JSON to XML in real time and shows it on the right. Step 3 — you can also type XML directly on the right, and it will be parsed back to JSON automatically. Step 4 — once the conversion is done, use the toolbar to copy or download the result. If the JSON root is an array, it is wrapped in a <root> element to remain valid XML; attributes are marked with the @_ prefix.

Typical scenarios: Integrating REST applications with legacy SOAP / Web Services that need JSON in but XML out. Financial, government and telecom industries whose message specs are XML-based and must round-trip with JSON front-ends. Working with Android layout files, Maven pom.xml, RSS feeds, and other XML data that is easier to process once converted to JSON. Quickly switching Postman or Swagger sample payloads between JSON and XML to fit different back-ends.

Technical notes: The tool follows the W3C XML 1.0 specification; XML input must be well-formed or a parse error is thrown. Object keys that contain reserved XML characters (such as & or <) are automatically entity-escaped. Arrays are expanded to multiple sibling elements with the same tag name. Numbers and booleans in JSON become text nodes in XML; when parsed back, they may be kept as the original string.

Privacy: All conversion is performed locally in your browser. The JSON or XML you enter never leaves your device, so it is safe to use with commercial-sensitive API payloads.
