Description
To decode a Base64-encoded 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 Base64 encoded.
To decode a Base64-encoded 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.
Example 1
Base64Decode(Products::Base64;"question.png") returns 
 when Products::Base64 is set to a string that begins with "iVBORw0KGgoAAAANSUhEUgAAAB8". The Base64 string in this example was shortened for readability.
