Grouped Unique combinations generator

Job ID: 31385871

Budget: €30 – €250 EUR

I would need a macro which takes 1 list of items & makes grouped combinations of them.
So let`s say i have a list of items, I can divide all those items into anywhere from 2 to 5 groups (with variable amounts of items [from the list] in each group) & have unique combinations of those items within each group. Then i would need unique combinations of those same combinations we obtained from the groups.

Excel file gives a very good indication of the output i am looking for.
