Don't do spreadsheet stuff because I don't really get it, but what I did in the past was to take a blank calendar.
Each blank sheet corresponded to the month I desired to plan my menus, then I went thusly:
Each week included a C (chicken/poultry), F (fish/seafood), B (beef), P (pork), L/V (lamb/veal), L (leftovers), O (other or eating out).
I rotated these codes every week and applied recipes to correspond and made my grocery lists to take care of the necessary ingredients and take advantage of grocery store specials.
Worked for me for years and I still have many of the calendars to remind me of some of the recipes we so enjoyed.
