I actually just created a module in VBA which does all of the work. It takes my ranged list and creates a comma-delimited string which is output into the cell of my choice:
`Function csvRange(myRange As Range)
Dim csvRangeOutput
Dim entry as variant
For Each entry In myRange
If Not IsEmpty(entry.Value) Then
csvRangeOutput = csvRangeOutput & entry.Value & ","
End If
Next
csvRange = Left(csvRangeOutput, Len(csvRangeOutput) - 1)
End Function
So then in my cell, I just put `=csvRange(A:A)` and it gives me the comma-delimited list.
