Returns either container or text content from text encoded in Base64 format.




text - Base64 text to decode.

fileNameWithExtension - the filename and extension for the file created from the decoded Base64 text.

Data type returned 

text, container

Originated in 

FileMaker Pro 13.0


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 Help button when Products::Base64 is set to a string that begins with "iVBORw0KGgoAAAANSUhEUgAAAB8". The Base64 string in this example was shortened for readability.
