Excelize - Golang 操作 Office Excel 文档类库

excelize_golang_library_for_reading_and_writing_xlsx_files_1

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)
 }
}

还有其他一些功能,在这里就不一一列举了,详细使用文档以及获取后期的维护更新可以从项目的主页获取 https://github.com/Luxurioust/excelize
