Support reads and writes XLSX file generated by Office Excel 2007 and later. Support save file without losing original charts of XLSX. The full API docs can be seen using go's built-in documentation tool, or online at [godoc.org](https://godoc.org/github.com/Luxurioust/excelize).

|
|
|
"github.com/Luxurioust/excelize"
|
|
)
|
|
|
|
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.
|
|
xlsx.SetActiveSheet(2)
|
|
// Save xlsx file by the given path.
|
|
err := xlsx.WriteTo("/tmp/Workbook.xlsx")
|
|
if err != nil {
|
|
fmt.Println(err)
|
|
os.Exit(1)

|
"github.com/Luxurioust/excelize"
|
|
)
|
|
|
|
func main() {
|
|
xlsx, err := excelize.OpenFile("/tmp/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 all the rows in a sheet.
|
|
rows := xlsx.GetRows("Sheet2")
|
|
for _, row := range rows {
|
|
for _, colCell := range row {
|
|
fmt.Print(colCell, "\t")
|
|
}
|
|
fmt.Println()
|
|
}
|
|
}
|
|
```
|
|
|

|
|
|
|
"github.com/Luxurioust/excelize"
|
|
)
|
|
|
|
func main() {
|
|
xlsx, err := excelize.OpenFile("/tmp/Workbook.xlsx")
|
|
if err != nil {
|
|
fmt.Println(err)
|
|
os.Exit(1)
|
|
}
|
|
// Insert a picture.
|
|
err = xlsx.AddPicture("Sheet1", "A2", "/tmp/image1.gif", 0, 0, 1, 1)
|
|
if err != nil {
|
|
fmt.Println(err)
|
|
}
|
|
// Insert a picture to sheet with scaling.
|
|
err = xlsx.AddPicture("Sheet1", "D2", "/tmp/image2.jpg", 0, 0, 0.5, 0.5)
|
|
if err != nil {
|
|
fmt.Println(err)
|
|

|
err = xlsx.AddPicture("Sheet1", "H2", "/tmp/image3.png", 15, 10, 1, 1)
