func main() {
 xlsx := excelize.CreateFile()
 // Create a new sheet.
 xlsx.NewSheet(2, "Sheet2")
 // Set value of a cell.
 xlsx.SetCellValue("Sheet2", "A2", "Hello world.")
 xlsx.SetCellValue("Sheet1", "B2", 100)
 // Set active sheet of the workbook.

func main() {
 xlsx, err := excelize.OpenFile("./Workbook.xlsx")
 if err != nil {
 fmt.Println(err)
 os.Exit(1)
 }
 // Get value from cell by given sheet index and axis.
 cell := xlsx.GetCellValue("Sheet1", "B2")
 fmt.Println(cell)
 // Get sheet index.
 index := xlsx.GetSheetIndex("Sheet2")
 // Get all the rows in a sheet.
 rows := xlsx.GetRows("sheet" + strconv.Itoa(index))
 for _, row := range rows {
 for _, colCell := range row {
 fmt.Print(colCell, "\t")

	values := map[string]int{"B2": 2, "C2": 3, "D2": 3, "B3": 5, "C3": 2, "D3": 4, "B4": 6, "C4": 7, "D4": 8}
	xlsx := excelize.CreateFile()
	for k, v := range categories {
		xlsx.SetCellValue("Sheet1", k, v)
	}
	for k, v := range values {
		xlsx.SetCellValue("Sheet1", k, v)
	}
	xlsx.AddChart("Sheet1", "E1", `{"type":"bar3D","series":[{"name":"=Sheet1!$A2ドル","categories":"=Sheet1!$B1ドル:$D1ドル","values":"=Sheet1!$B2ドル:$D2ドル"},{"name":"=Sheet1!$A2ドル","categories":"=Sheet1!$B1ドル:$D1ドル","values":"=Sheet1!$B3ドル:$D3ドル"},{"name":"=Sheet1!$A3ドル","categories":"=Sheet1!$B1ドル:$D1ドル","values":"=Sheet1!$B4ドル:$D4ドル"}],"title":{"name":"Fruit 3D Line Chart"}}`)
