SUMMARY

In Microsoft Excel, you can use a macro to concatenate the data in two adjacent columns and display the result in the column to the right of the columns that contain your data. This article contains a sample Microsoft Visual Basic for Applications macro (Sub procedure) to accomplish this.

This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements.

Sample Visual Basic Procedure

Sub ConcatColumns()

   Do While ActiveCell <> ""  'Loops until the active cell is blank.

      'The "&" must have a space on both sides or it will be
      'treated as a variable type of long integer.

      ActiveCell.Offset(0, 1).FormulaR1C1 = _
         ActiveCell.Offset(0, -1) & " " & ActiveCell.Offset(0, 0)

      ActiveCell.Offset(1, 0).Select
   Loop

End Sub
NOTE: The statement ActiveCell.Offset(0, 1).FormulaR1C1 can be replaced with the statement ActiveCell.Offset(0, 1).Formula. They can be used with equal success if you are using text and numbers only (not formulas). The R1C1 used at the end of the first statement refers to row one, column one and is the form used in examples in Help.

To Use the Macro in Microsoft Excel 2000

  1. Open the workbook which contains the data.
  2. Press ALT+F11 to activate the Visual Basic Editor.
  3. Click Module on the Insert menu to insert a module. Type the macro above in the module's code window.
  4. Click Close and Return to Microsoft Excel on the File menu.
  5. Select the worksheet that contains the data that you want to concatenate.
