Excelize 是 Golang 编写的一个用来操作 Office Excel 文档类库，基于微软的 Office OpenXML 标准。可以使用它来读取、写入 XLSX 文件。相比较其他的开源类库，Excelize 支持写入原本带有图片(表)的文档，还支持向 Excel 中插入图片，并且在保存后不会丢失图表样式。
安装
go get github.com/Luxurioust/excelize
创建 XLSX
package main
import (
"fmt"
"os"
"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)
}
}
读写已有文档
package main
import (
"fmt"
"os"
"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()
}
}
向 Excel 中插入图片
package main
import (
"fmt"
"os"
_ "image/gif"
_ "image/jpeg"
_ "image/png"
"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", "")
if err != nil {
fmt.Println(err)
}
// Insert a picture to sheet with scaling.
err = xlsx.AddPicture("Sheet1", "D2", "/tmp/image2.jpg", `{"x_scale": 0.5, "y_scale": 0.5}`)
if err != nil {
fmt.Println(err)
}
// Insert a picture offset in the cell with printing support.
err = xlsx.AddPicture("Sheet1", "H2", "/tmp/image3.gif", `{"x_offset": 15, "y_offset": 10, "print_obj": true, "lock_aspect_ratio": false, "locked": false}`)
if err != nil {
fmt.Println(err)
}
// Save the xlsx file with the origin path.
err = xlsx.Save()
if err != nil {
fmt.Println(err)
os.Exit(1)
}
}
