Using the Change Case choice under the Options menu you can instruct Macify to make the whole file uppercase or lowercase, or to make the first letter of every sentence uppercase or the first letter of every word uppercase. This addition was inspired by the need to convert database files sent to the Macintosh from another computer from all uppercase to upper/lower. For that particular project the option to capitalize each word was used.
Note that Change Case also explicitly sets into lowercase any character that is not supposed to be in uppercase.
