JSON to XML Converter

JSON to XML Converter rewrites a JSON document as XML. It is most often needed when a modern service produces JSON and an older system, a SOAP endpoint or an enterprise import routine insists on XML.

The two formats do not map perfectly onto one another, so the conversion makes some decisions and tells you what they are. JSON object keys become element names. Values become element text. Arrays become repeated sibling elements, named after the key where that produces a valid name, because XML has no array type of its own.

Names are the sharp edge. XML element names cannot start with a digit, cannot contain spaces, and cannot be empty, while JSON keys can be any string at all. Keys that would produce invalid names are rewritten predictably and the change is reported, so you are never handed XML that silently will not parse.

Escaping is handled throughout: ampersands, angle brackets and quotes in values are turned into entities, so text containing markup does not break the document. The output is indented and ends up parsing cleanly in any XML reader.

Everything runs inside your browser. Nothing you paste is uploaded, logged or stored, which matters when the input is a client list, an internal URL map or anything else you would not post publicly.

• Well-formed, indented XML output
• Arrays become repeated sibling elements
• Invalid element names rewritten and reported, never silently broken
• Correct escaping of ampersands, angle brackets and quotes
• Configurable root element name
• Clear JSON parse errors with the position of the problem
• Runs entirely in your browser

The json to xml converter is used by writers, developers, students, marketers and anyone else who needs the job done once without installing software. Common cases include:

• Feeding JSON data into a system that only accepts XML
• Preparing a payload for a SOAP service
• Converting a configuration file between formats
• Producing XML for an import routine
• Comparing how the same data looks in both formats
