Trying to find the most popular combinations as per the spreadsheet. The desired output should list all the unique ordered combinations, eg Prod A and Prod B is equivalent to Prod B and Prod A. Looking for an Excel 2019 solution with formulae and ok to have helper columns.

Thanks ISY, I'm playing around with your solution but I'm getting error messages in D2, ie VALUE errors. I 'll keep trying to see if I can get this to work.

There are some extra quotes in the formula, try
Excel Formula:
=BYROW(C2:C9,LAMBDA(k,TEXTJOIN(", ",,SORT(TEXTSPLIT(k,", "),,,1))))
