Concordo con Alex sulla creazione di un template in Excel, vedi questo codice che crea un template in Excel , esporta dei dati e crea un grafico.
Const xlDataLabelsShowPercent = 3
Set objExcel = CreateObject("Excel.Application")
objExcel.Visible = True
Set objWorkbook = objExcel.Workbooks.Add()
Set objWorksheet = objWorkbook.Worksheets(1)
objWorksheet.Cells(1,1) = "Operating System"
objWorksheet.Cells(2,1) = "Windows Server 2003"
objWorksheet.Cells(3,1) = "Windows XP"
objWorksheet.Cells(4,1) = "Windows 2000"
objWorksheet.Cells(5,1) = "Windows NT 4.0"
objWorksheet.Cells(6,1) = "Other"
objWorksheet.Cells(1,2) = "Number of Computers"
objWorksheet.Cells(2,2) = 145
objWorksheet.Cells(3,2) = 487
objWorksheet.Cells(4,2) = 211
objWorksheet.Cells(5,2) = 41
objWorksheet.Cells(6,2) = 56
Set objRange = objWorksheet.UsedRange
objRange.Select
Set colCharts = objExcel.Charts
colCharts.Add()
Set objChart = colCharts(1)
objChart.Activate
objChart.ChartType = 70
objChart.Elevation = 30
objChart.Rotation = 80
objChart.ApplyDataLabels xlDataLabelsShowPercent
objChart.PlotArea.Fill.Visible = False
objChart.PlotArea.Border.LineStyle = -4142
objChart.SeriesCollection(1).DataLabels.Font.Size = 14
objChart.SeriesCollection(1).DataLabels.Font.ColorIndex = 2
objChart.ChartArea.Fill.ForeColor.SchemeColor = 49
objChart.ChartArea.Fill.BackColor.SchemeColor = 23
objChart.ChartArea.Fill.TwoColorGradient 1,1
objChart.ChartTitle.Font.Size = 24
objChart.ChartTitle.Font.ColorIndex = 2
objChart.Legend.Shadow = True
for i = 0 to 300
Wscript.Sleep 200
objChart.Rotation = objChart.Rotation + 1
next
