JSON to XML

JSON and XML both describe structured data, but older APIs, feeds and enterprise systems often still expect XML. This converter turns any JSON value into well-formed XML in your browser.

Everything is wrapped in a root element. Object keys become child elements, and values become their text. A top-level array becomes a series of item elements, while an array under a key repeats that key, so {"tag": ["a", "b"]} becomes <tag>a</tag><tag>b</tag>. Keys starting with @_ become attributes and a #text key becomes the element's text, which matches what the XML to JSON converter produces, so data can go back and forth. If your JSON is a single object that wraps everything, such as {"catalog": {...}}, its key is used as the root element unless you set one.

XML has stricter naming rules than JSON, so names are fixed where needed: spaces and symbols become underscores and a name that starts with a digit gets an underscore in front. Ampersands and angle brackets in text, and quotes in attributes, are escaped. The file starts with an XML declaration for UTF-8.
