Code formatting has been applied to improve legibility.

ItemArrayAArrayB
Item1
["A","B","C"]
["1","2","3"]
Item2
["A","B"]
["A","B","C"]
Item3
["D","E","F"]
["4","5","6"]

Transform:

You can apply the following transforms in the following order. Note that the column names must be different from the transform name, which is a reserved word.

derive value:ARRAYCONCAT([Letters,Numerals]) as:'concat2'

derive value:ARRAYINTERSECT([Letters,Numerals]) as:'intersection2'

derive value:ARRAYCROSS([Letters,Numerals]) as:'cross2'

derive value:ARRAYUNIQUE([Letters,Numerals]) as:'unique2'

Results:
