array

Ok, now that I know what is happening, this is an easy fix.  Two things:

Array:  Take the reading of your Array file out of the FOR loop.  It only needs read once.  The autoindexing of the output on the FOR loop is just making it a 3D array.

Array 2:  Change the data type for the Spreadsheet String to Array to a 1D array of string.

For the combining, I think you will need to use Transpose 2D Array on the main array, then use Build Array to append Array 2 to Array.  Then transpose again to put it all the way you want.

Ok, I have a small correction where I told you to use Build Array.  You will need to transpose Array 2 as well.  Here I gave you 2 options of appending columns to a 2D array.
