The code to concatenate with the loop is helpful for my case because I need to insert a space. Thanks
I wanted to ask about the reason for the 'x' in the statement where the variables are defined.
    Dim t, i As Long, arr1, arr2, arr3, x As Long
The x is never used in the VBA script but it is needed or a compile error for arr3 comes up if it is removed.
What is the purpose of the 'x'  ?
