Split an array

How could I divide an array variable of 600 elements into 3 different arrays of 200 elements each?

I have an excel input in which one of the fields can contain up to 600 elements (in an array variable). I need to divide those 600 elements into blocks of 200 and make them new rows of the input excel.

Assign activity
mySegments | List(Of String()) =
myStringArray.Chunk(200).toList

we can also adapt to other DataTypes
