I have created an ultra light packing tool in excel. It gives you a way to create your own master list for food, clothing, and equipment with weights and weight ratios. It will also let you know if you are meeting your calorie, protein, carb needs, and pack weight requirements. It will generate custom packing reports for each person and a daily menu sheet as well.
This started small, but soon became a very large project. But it is a very useful tool for planning your trips.
