Convert between JSON and XML in both directions. Paste your data on either side, choose a direction, and get an instant result — all processing happens in your browser, nothing ever touches a server.
JSON (JavaScript Object Notation) and XML (Extensible Markup Language) are two of the most widely used data interchange formats in web development. While JSON has become the default for modern REST APIs thanks to its compact, human-readable syntax, XML remains dominant in enterprise environments, SOAP web services, configuration files, document stores, and many legacy systems.
Converting between the two formats lets you bridge those worlds — for example, consuming a JSON API response and forwarding it to an XML-based service, or parsing XML from a third-party feed and using it in a JavaScript application. This tool handles both directions and preserves nested objects, arrays, and attributes as faithfully as possible.

The JSON and XML data models are not perfectly symmetrical, so some information can be lost or transformed during conversion. XML supports attributes, mixed content (text interleaved with child elements), processing instructions, and comments — none of which have a direct equivalent in JSON. This tool makes sensible choices (XML attributes become JSON keys prefixed with @; text content becomes a #text key when attributes are also present), but complex XML documents with heavy use of attributes or mixed content may require manual adjustment after conversion.
For simple data exchange scenarios — flat objects, nested structures, arrays of records — the conversion is lossless in both directions. If you need guaranteed round-trip fidelity for complex schemas, consider using a dedicated library in your build pipeline (e.g. fast-xml-parser for Node.js) where you have full control over the mapping rules.
