Convert m4r to dotm

What is the difference between .m4r and .dotm?

Description: M4R is an iTunes ringtone file that stores mono channel audio. They are identical to the M4A format files only that they are correctly used for ringtones.; A DOTM file is a Word Open XML Macro-Enabled Document Template used by Microsoft Word, part of the Microsoft Office suite. It is a template file that contains default layouts and settings for a document, including macros, which are small programs that automate repetitive tasks. Unlike standard Word templates (.dotx), which do not support macros, DOTM files enable users to include custom macros that can be executed within the document. This feature is particularly useful for creating standardized documents that require specific automated functions.
