In continuation from here

We already covered here how to create the form, set references and place the required buttons. Now we will create a blank workbook.

Double click the first button Create and paste this code. I will be commenting the code so that you can understand what the code does.

Imports Excel = Microsoft.Office.Interop.Excel

Public Class Form1
    '~~> Define your Excel Objects
    Dim xlApp As New Excel.Application
    Dim xlWorkBook As Excel.Workbook

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        '~~> Add a New Workbook
        xlWorkBook = xlApp.Workbooks.Add

        '~~> Display Excel
        xlApp.Visible = True
    End Sub

    Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
        Me.Close()
    End Sub
End Class

Now when you run the project, your form will launch and when you click on “Create” button, Excel will launch and a new workbook will be created.
