JSON to XML

Convert JSON to well-formed XML

Many systems still speak XML: SOAP services, publishing workflows, government and financial interfaces, older import formats. JSON to XML converts a JSON document into indented, well-formed XML with a declaration, ready for those systems or for a stylesheet.

Paste the JSON or drop a .json file and, if you like, name the root element. Each object key becomes an element; arrays become repeated elements with the same name; nested objects become nested elements. Two conventions let you control the output precisely: a key that starts with @ becomes an attribute of its parent element, and a key named #text becomes the element's text content, which is exactly how XML to JSON writes attributes and mixed content, so a round trip preserves them. Names that are not legal in XML, such as ones starting with a digit or containing spaces, are made legal. Booleans are written as true and false, null as an empty element. If the JSON is an object with a single key holding an object or a list, that key becomes the root element.

Special characters are escaped correctly and the file is UTF-8. Invalid JSON is reported with its line and column. To go the other way use XML to JSON, and to inspect a large result use the JSON Formatter or Compare JSON.
