Excel - How to Dim and Set a variable workbook name in VBA?

In VBA, you can declare and set a variable to represent a workbook using the Workbook data type. Here's how you can declare and set a variable to represent a workbook:

Sub Example() Dim wb As Workbook ' Set the workbook object to refer to a specific workbook Set wb = Workbooks("YourWorkbookName.xlsx") ' Replace "YourWorkbookName.xlsx" with the name of your workbook ' Now you can use 'wb' to refer to the workbook ' For example: MsgBox wb.Name ' Display the name of the workbook ' You can also perform operations on the workbook using 'wb' ' For example: ' wb.Save ' Save the workbook ' Don't forget to release the workbook object when you're done with it Set wb = Nothing End Sub

In this example:

  • Dim wb As Workbook declares a variable named wb of type Workbook.
  • Set wb = Workbooks("YourWorkbookName.xlsx") sets the wb variable to refer to the workbook with the specified name. Replace "YourWorkbookName.xlsx" with the name of your workbook.
  • You can now use wb to refer to the workbook and perform operations on it.

Make sure to release the workbook object by setting it to Nothing when you're done with it to free up memory resources.
