Best Solution

You need to specify a formula in first cell of A and then simply propagate it across all the column.

  1. In column A, select the cell with value "aa1"
  2. Press F2 to edit that cell
  3. Type =CONCATENATE("a",$C1) and press Enter
  4. Press Ctrl+C to copy the cell you just edited
  5. With the mouse (or with keys shift+down) select the next two cells in column A (aa2 and aa3)
  6. Press Ctrl+V

In VBA, you need something like this:

Sub Button1_Click()
    For Each cell In ActiveSheet.Range("A1:A3").Cells
        cell.Value = "a" + ActiveSheet.Cells(cell.row, 3)
    Next
End Sub

You need to specify the range you want to change, in this case from A1 to A3 and then simply change the value for each cell as the concatenation of "a" with the cell value on same row but column 3 (C)
