Golang操作Office Excel 文档类库Excelize

转自：http://studygolang.com/articles/9623

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 mainimport (    "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 mainimport (    "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 mainimport (    "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
