There are a number of decryption options. When an encryption is made the person making the encryption can make the output a file such
such as an HTML file. The default option is to get the file type and name specified by the encryption, however you can also choose to view the decryption and
override the file name and file type specified by the creator of the encryption.
To do this change the default to "Output to Excel only" before you click on the Decrypt button.
