SUMMARY

In Microsoft Excel, you can use a Microsoft Visual Basic for Applications macro to sum or subtract two ranges of data and to then place the result into a third range without using formulas in the cells. You can do this in the same workbook or from more than one workbook into a workbook using defined names.

There are several ways to perform the task of adding or subtracting columns

of data together. You can use a For Each...Next loop in the same workbook to subtract values in one column from another column and have the results appear in a third column. For an example of how to do this using Visual Basic code, perform the following steps in Microsoft Excel:

1. Open a new worksheet, and in A1:A10, enter some random numbers.

2. In B1:B10, enter some random numbers.

3. In a Visual Basic module, type the following:

      Sub MyTotal()
          Dim CurCell As Object
          For Each CurCell In Range("C1:C10")
              CurCell.Value = CurCell.Offset(0, -2).Value _
                  - CurCell.Offset(0, -1).Value
          Next
      End Sub

4. Run the macro.

The results of the subtraction appear in C1:C10.

You can use the same code to add the columns. To do this, just change the minus sign to a plus sign in the CurCell.Value line, as follows:

   CurCell.Value = CurCell.Offset(0, -2).Value _
       + CurCell.Offset(0, -1).Value

To add or subtract from different workbooks using Visual Basic code, use the following steps:

1. Open a workbook (Book1), and in range A1:A10, insert random numbers.

2. In range A1:A10 of a second workbook (Book2), insert random numbers.

3. On a Visual Basic module sheet, type the following:

      Sub TotalData()
          Dim File1 As Object, File2 As Object, CurCell As Object

          ' Where the first column of data is located in Book1 on Sheet1
          ' in range A1:A10.
          Set File1 = Workbooks("Book1").Sheets("Sheet1").Range("A1:A10")

          ' We are now dealing with the second column of data.
          Set File2 = Workbooks("Book2").Sheets("Sheet1").Range("A1:A10")

          For Each CurCell In Range("A1:A10")

              ' To add instead of subtract, change the minus sign
              ' to a plus sign.
              CurCell.Value = File1.Cells(CurCell.Row, 1).Value - _
                  File2.Cells(CurCell.Row, 1).Value

          Next
      End Sub

4. Run the macro.
