Question : Excel VBA: How to run dynamically created code/string

Hey Experts,

I am trying to execute a string that I have dynamically created. I build this code through a loop, then want to execute it afterwords. Is there a function or way that I can do this? Or if there is not, is there an alternative way to solve my issue? See Code for what I am trying to do.

Function RunCode(TotalRows)
    Dim SelectionString As String
    Dim counter As Integer
        SelectionString = "Selection.TextToColumns Destination:=ActiveCell, datatype:=xlFixedWidth, FieldInfo:=Array("
        Do
        If (counter = 0) Then
            SelectionString = SelectionString & "Array(" & myArray(counter) & ", 2)"
        Else
            SelectionString = SelectionString & ", Array(" & myArray(counter) & ", 2)"
        End If
        counter = counter + 1
    Loop Until (counter > TotalRows)
    SelectionString = SelectionString & "), TrailingMinusNumbers:=True"
    MsgBox (SelectionString)
    'This string successfully produces the function to convert text in my selection to columns.
    'However, SelectionString is a string obviously, and looks like the function I need, but I need a way to execute it.
    'Or I need a different way to do this. The TotalRows changes each time, so I need a way to build this large 'FieldInfo' array dynamically
    'NOTE: myArray is a global array, don't worry about what is in it.
End Function

Answer : Excel VBA: How to run dynamically created code/string

I wrote the following code for another problem, i have taken out the unnecessary stuff, I believe this is a much better way to approach opening the said workbook, then closing it, then quitting excel

notice the private function at the bottom, also this assumes you will add a reference to excel in the project and also use Imports Excel = microsoft.blah.blah.blha
