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。
