Excelize 是 Golang 編寫的一個用來操作 Office Excel 文檔類庫，基於微軟的 Office OpenXML 標準。可以使用它來讀取、寫入 XLSX 檔案。相比較其他的開源類庫，Excelize 支援寫入原本帶有圖片(表)的文檔，還支援向 Excel 中插入圖片，並且在儲存後不會丟失圖表樣式。

建立 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)    }}

讀寫已有文檔

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 中插入圖表

650) this.width=650;" src="https://raw.githubusercontent.com/Luxurioust/excelize/master/test/images/chart.png" />

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 中插入圖片

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)    }}
