是 Go 语言编写的一个用来操作 Office Excel 文档类库，基于 ECMA-376 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/360EntSecGroup-Skylar/excelize

创建 XLSX

package mainimport (    "fmt"    "github.com/360EntSecGroup-Skylar/excelize")func main() {    f := excelize.NewFile()    // Create a new sheet.    index := f.NewSheet("Sheet2")    // Set value of a cell.    f.SetCellValue("Sheet2", "A2", "Hello world.")    f.SetCellValue("Sheet1", "B2", 100)    // Set active sheet of the workbook.    f.SetActiveSheet(index)    // Save xlsx file by the given path.    err := f.SaveAs("./Book1.xlsx")    if err != nil {        fmt.Println(err)    }}

读取已有文档

package mainimport (    "fmt"    "github.com/360EntSecGroup-Skylar/excelize")func main() {    f, err := excelize.OpenFile("./Book1.xlsx")    if err != nil {        fmt.Println(err)        return    }    // Get value from cell by given worksheet name and axis.    cell, err := f.GetCellValue("Sheet1", "B2")    if err != nil {        fmt.Println(err)        return    }    fmt.Println(cell)    // Get all the rows in the Sheet1.    rows, err := f.GetRows("Sheet1")    for _, row := range rows {        for _, colCell := range row {            fmt.Print(colCell, "\t")        }        fmt.Println()    }}

向 Excel 中插入图表

package mainimport (    "fmt"    "github.com/360EntSecGroup-Skylar/excelize")func main() {    categories := map[string]string{"A2": "Small", "A3": "Normal", "A4": "Large", "B1": "Apple", "C1": "Orange", "D1": "Pear"}    values := map[string]int{"B2": 2, "C2": 3, "D2": 3, "B3": 5, "C3": 2, "D3": 4, "B4": 6, "C4": 7, "D4": 8}    f := excelize.NewFile()    for k, v := range categories {        f.SetCellValue("Sheet1", k, v)    }    for k, v := range values {        f.SetCellValue("Sheet1", k, v)    }    err := f.AddChart("Sheet1", "E1", `{"type":"col3DClustered","series":[{"name":"Sheet1!$A$2","categories":"Sheet1!$B$1:$D$1","values":"Sheet1!$B$2:$D$2"},{"name":"Sheet1!$A$3","categories":"Sheet1!$B$1:$D$1","values":"Sheet1!$B$3:$D$3"},{"name":"Sheet1!$A$4","categories":"Sheet1!$B$1:$D$1","values":"Sheet1!$B$4:$D$4"}],"title":{"name":"Fruit 3D Clustered Column Chart"}}`)    if err != nil {        fmt.Println(err)        return    }    // Save xlsx file by the given path.    err = f.SaveAs("./Book1.xlsx")    if err != nil {        fmt.Println(err)    }}

向 Excel 中插入图片

package mainimport (    "fmt"    _ "image/gif"    _ "image/jpeg"    _ "image/png"    "github.com/360EntSecGroup-Skylar/excelize")func main() {    f, err := excelize.OpenFile("./Book1.xlsx")    if err != nil {        fmt.Println(err)        return    }    // Insert a picture.    err = f.AddPicture("Sheet1", "A2", "./image1.png", "")    if err != nil {        fmt.Println(err)    }    // Insert a picture to worksheet with scaling.    err = f.AddPicture("Sheet1", "D2", "./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 = f.AddPicture("Sheet1", "H2", "./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 = f.Save()    if err != nil {        fmt.Println(err)    }}
