Go 语言读写 Excel 基础库

Excelize 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/xuri/excelize/v2 

创建 XLSX

package main import ( "fmt" "github.com/xuri/excelize/v2" ) 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 main import ( "fmt" "github.com/xuri/excelize/v2" ) 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 main import ( "fmt" "github.com/xuri/excelize/v2" ) 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 main import ( "fmt" _ "image/gif" _ "image/jpeg" _ "image/png" "github.com/xuri/excelize/v2" ) 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) } }
