Combine the Workbooks in a Folder

The following procedure creates a new workbook containing one worksheet in which to combine the data. Then it copies the data from "Sheet1" of each workbook in the specified folder to the worksheet in the newly created workbook.

Note that it's assumed that the source data contains column headers in the first row. Also, the workbook containing this code can be located in the same folder as the other workbooks.

Tip  A worksheet can be referenced by index number instead of a sheet name. Therefore, to refer to the first sheet of each workbook instead of "Sheet1", replace...

Set wksSource = wkbSource.Worksheets("Sheet1")


Set wksSource = wkbSource.Worksheets(1)

Where to Put the Code

  1. Open the workbook in which to store the code.
  2. Open the Visual Basic Editor (Alt+F11).
  3. Insert a standard module (Insert > Module).
  4. Copy/paste the above code into the module.
  5. Return to Microsoft Excel (Alt+Q).
  6. Save the workbook.

How to Use the Macro

  1. Display the Macro dialog box (Alt+F8).
  2. Click/select the macro called "CombineWorkbooks".
  3. Click/select "Run".
