介绍

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("./Workbook.xlsx") if err != nil {  fmt.Println(err)  os.Exit(1) }}

读写已有文档

package mainimport ( "fmt" "os" "strconv" "github.com/Luxurioust/excelize")func main() { xlsx, err := excelize.OpenFile("./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 sheet index. index := xlsx.GetSheetIndex("Sheet2") // Get all the rows in a sheet. rows := xlsx.GetRows("sheet" + strconv.Itoa(index)) for _, row := range rows {  for _, colCell := range row {   fmt.Print(colCell, "\t")  }  fmt.Println() }}

向 Excel 中插入图表

package mainimport ( "fmt" "os" "github.com/Luxurioust/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} xlsx := excelize.CreateFile() for k, v := range categories {  xlsx.SetCellValue("Sheet1", k, v) } for k, v := range values {  xlsx.SetCellValue("Sheet1", k, v) } xlsx.AddChart("Sheet1", "E1", `{"type":"bar3D","series":[{"name":"=Sheet1!$A$2","categories":"=Sheet1!$B$1:$D$1","values":"=Sheet1!$B$2:$D$2"},{"name":"=Sheet1!$A$2","categories":"=Sheet1!$B$1:$D$1","values":"=Sheet1!$B$3:$D$3"},{"name":"=Sheet1!$A$3","categories":"=Sheet1!$B$1:$D$1","values":"=Sheet1!$B$4:$D$4"}],"title":{"name":"Fruit 3D Line Chart"}}`) // Save xlsx file by the given path. err := xlsx.WriteTo("./Workbook.xlsx") if err != nil {  fmt.Println(err)  os.Exit(1) }}

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("./Workbook.xlsx") if err != nil {  fmt.Println(err)  os.Exit(1) } // Insert a picture. err = xlsx.AddPicture("Sheet1", "A2", "./image1.gif", "") if err != nil {  fmt.Println(err) } // Insert a picture to sheet with scaling. err = xlsx.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 = xlsx.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 = 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
