Cisco config generator excel Macro tools

Hi and good day users, friends and pals!
We know that Cisco Systems Inc. is a multinational corporation that designs, manufactures and sells networking equipments. Now I want to create a bulk configuration file from a template for staging. But it seems that I have been struggling doing it! Now my question is, how can I do it? Do I need Cisco config generator excel macro tools for making it? Any help would be nice!
