Description
To decode a hexadecimal value and return the result in a text field (or a variable used as text data), for the data parameter, specify text that was in UTF-8 format and then hex encoded.
To decode a hexadecimal value that represents binary data, return the result in a container field (or a variable used as container data) and specify the fileNameWithExtension parameter. If a filename and extension are not specified, this function returns text rather than container data.
