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 main

import (
    "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 main

import (
    "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 main

import (
    "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
