Hey
As i read the instructions of this project, i think you need, the idea programmed anyway but the output results in excel.
there is a package in r called combinat which does exactly what you need, we can use it and then write the results in excel file, incase you dont have r, i can make a shiny app which can work without r. i can as well do everything in excel if needed. For sure i have dozens of ideas on how to implement this project. please hire me
Thank you
