This helper is available in the Winter ’27 release of Marketing Cloud Next.

1{{stringToHex sourceString [charSet=CHARSET]}}

The function returns a hexadecimal string that represents the encoded characters in sourceString.

This example converts a string of text to its UTF-8 hexadecimal representation.

1{{stringToHex "Hello world!"}}

The function returns:

148656c6c6f20776f726c6421

This example converts the same string, but specifies UTF-16 encoding. Each character requires more bytes in UTF-16, so the resulting string is longer.

1{{stringToHex "Hello world!" charSet="UTF-16"}}

The function returns:
