Golang 读写XLSX文件

1. 包地址

https://github.com/360EntSecGroup-Skylar/excelize

2. 使用说明

此包的readme已经有比较不错的使用说明了，这里不做过多深入，简单引用/翻译下吧。

• 安装：

  go get -u github.com/360EntSecGroup-Skylar/excelize
  #如果使用go mod环境：
  go get -u github.com/360EntSecGroup-Skylar/excelize@master
  或者：go -u get github.com/360EntSecGroup-Skylar/excelize@tag

• 文件(sheet表)的创建/写入

  package main
  import (
    "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)
    }
  }

• 文件的读取

  package main
  import (
    "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()
    }
  }

• 在文件中插入图表
  

  package main
  import (
    "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)
    }
  }

• 在文件中插入图片

  package main
  import (
    "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)
    }
  }

3. 注意事项

1. 这个包目前有两个branch，go get默认为master。如果需要使用v2，则go get地址应该为：github.com/360EntSecGroup-Skylar/excelize/v2 ， 不然指定v2的tag时会失败。
