IconVault's JSON to XML converter translates data between the two formats in one click. JSON to XML uses a custom serializer with proper XML escaping and a customizable root element, and arrays become repeated elements using the singular of the key name, so tags becomes tag.

XML to JSON parses your markup with the browser's DOMParser and rebuilds it as pretty-printed JSON. One honest note: XML has no data types, so numbers and booleans come back as strings. Everything runs fully in your browser with nothing uploaded, it is free to try (heavy repeated use may ask for Pro), and you can copy the result or download it as a file.
