|Decodes Encodes the specified {{Code|$key}} to its original string representation, using (with the optional {{Code|$lax}} conversion method) to a valid NCName representation, which can be used to create an element node:* An empty string is converted to a single underscore ({{Code|_}}).<br />Keys supplied * Existing underscores are rewritten to this function two underscores ({{Code|__}}).* Characters that are usually no valid NCName characters are rewritten to an underscore and the character’s four-digit Unicode. For example, the exclamation mark {{Code|?}} is transformed to {{Code|_003f}}.* If lax conversion is chosen, invalid characters are replaced with underscores or (when invalid as first character of an element names from documents that have been created name) prefixed with an underscore. The resulting string may be better readable, but it cannot necessarily be converted back to the original form.This encoding is employed by the {{Code|direct}} conversion format in the [[JSON Module]] and the [[CSV Module]] and the {{Code|direct}} conversion format.

* <code>element { convert:decodeencode-key('_0021')"!")} { }</code> yields creates a new element with an encoded name: <code>!<_0021/code>.* <code>json:doc("doc.json")//* ! convert:decode-key(name())</code> yields the original string representation of all names of a JSON document.
