Sum Values By Group. Nice to have a good reference for users not familiar with excel formula scripting. I have used the same script but I cannot find a way to sort the result based on the summed values, in your example, I like to get summed valued from highest to lowest (105, 96, 83). I was able to do it by creating another column (say column D) to copy the summed amount corresponding to product (say, Blue will have 96 for D2, D3, D4 / 83 for D5, D6 and so on) then sort column D. But I think that is a crude way of doing it. Is there a built-in function in Excel or Kutools to have the sum and sort (based on summed values). Thanks
