Your are right, it is a struggle. I tried adding helper columns for size and measurement (mm, ml, g..) but still 23/13 came before 23/6 or 23/06 so the helper columns were discarded. I guess we will have to live with the not so perfect sort results.

If I edited to 23/06 on the List sheet it came out in the correct order on ListSort sheet!

Ooops. My mistake. Yes, placing a zero before the single digits would sort the data the way they should be sorted. Thank you.
