            Dim xlWorkBook As Microsoft.Office.Interop.Excel.Workbook
            Dim xlWorkSheet As Microsoft.Office.Interop.Excel.Worksheet
            Dim misValue As Object = System.Reflection.Missing.Value
            Dim i As Integer
            Dim j As Integer
            xlApp = New Microsoft.Office.Interop.Excel.Application
            xlWorkBook = xlApp.Workbooks.Add(misValue)
            xlWorkSheet = xlWorkBook.Sheets("sheet1")
            xlWorkSheet.Columns.AutoFit()
            For i = 0 To DataGridView1.RowCount - 2
                For j = 0 To DataGridView1.ColumnCount - 1
                    For k As Integer = 1 To DataGridView1.Columns.Count
                        xlWorkSheet.Cells(1, k) = DataGridView1.Columns(k - 1).HeaderText
                        xlWorkSheet.Cells(i + 2, j + 1) = DataGridView1(j, i).Value.ToString()
                    Next
                Next
            Next
            Dim fName As String = "DataBuku"
            Using sfd As New SaveFileDialog
                sfd.Title = "Save As"
                sfd.OverwritePrompt = True
                sfd.FileName = fName
                sfd.DefaultExt = ".xlsx"
                sfd.Filter = "Excel Workbook(*.xlsx)|"
                sfd.AddExtension = True
                If sfd.ShowDialog() = DialogResult.OK Then
                    xlWorkSheet.SaveAs(sfd.FileName)
                    xlWorkBook.Close()
                    xlApp.Quit()
                    releaseObject(xlApp)
                    releaseObject(xlWorkBook)
                    releaseObject(xlWorkSheet)
                    MsgBox("Export Successfully !", MsgBoxStyle.Information, "== Notice ==")
                End If
            End Using
        Catch ex As Exception
            myconnection.Close()
            MsgBox("Error ! " & vbCrLf & "Error Code: " & ex.Message)
        End Try

3 Paste this code in range of Form1 Code.

  Private Sub ReleaseObject(ByVal obj As Object)
        Try
            System.Runtime.InteropServices.Marshal.ReleaseComObject(obj)
            obj = Nothing
        Catch ex As Exception
            obj = Nothing
        Finally
            GC.Collect()
        End Try
    End Sub
