本测试中使用的第三方库为：https://github.com/tealeg/xlsx ，其项目页上介绍“ ”Google Go (golang) library for reading and writing XLSX files. You should probably also checkout: https://github.com/360EntSecGroup-Skylar/excelize “ ，所以也可以引入https://github.com/360EntSecGroup-Skylar/excelize模块进行excel处理，不过其相较于python的模块来说，功能上还是比较弱。

一、读文件

1go get github.com/tealeg/xlsx

先安装依赖库。读取的源文件内容如下：

go-xlsx
go-xlsx

读取文件的源代码如下：

 1package main
 2import(
 3    "fmt"
 4    "github.com/tealeg/xlsx"
 5)
 6var (
 7    inFile = "test.xlsx"
 8)
 9func main(){
10    // 打开文件
11    xlFile, err := xlsx.OpenFile(inFile)
12    if err != nil {
13        fmt.Println(err.Error())
14        return
15    }
16    // 遍历sheet页读取
17    for _, sheet := range xlFile.Sheets {
18        fmt.Println("sheet name: ", sheet.Name)
19        //遍历行读取
20        for _, row := range sheet.Rows {
21            // 遍历每行的列读取
22            for _, cell := range row.Cells {
23                text := cell.String()
24                fmt.Printf("%20s", text)
25            }
26            fmt.Print("\n")
27        }
28    }
29    fmt.Println("\n\nimport success")
30}

执行结果如下：

1[root@localhost test]# go run rexcel.go
2sheet name:  Sheet1
3                site                 age               email
4      www.361way.com                  10      itybku@139.com
5import success

二、写文件

代码如下：

 1package main
 2import(
 3    "strconv"
 4    "fmt"
 5    "github.com/tealeg/xlsx"
 6)
 7var (
 8    outFile = "/tmp/out_student.xlsx"
 9)
10type Student struct{
11    Name string
12    age int
13    Phone string
14    Gender string
15    Mail string
16}
17func main(){
18    file := xlsx.NewFile()
19    sheet, err := file.AddSheet("student_list")
20    if err != nil {
21        fmt.Printf(err.Error())
22    }
23    stus := getStudents()
24    //add data
25    for _, stu := range stus{
26        row := sheet.AddRow()
27        nameCell := row.AddCell()
28        nameCell.Value = stu.Name
29        ageCell := row.AddCell()
30        ageCell.Value = strconv.Itoa(stu.age)
31        phoneCell := row.AddCell()
32        phoneCell.Value = stu.Phone
33        genderCell := row.AddCell()
34        genderCell.Value = stu.Gender
35        mailCell := row.AddCell()
36        mailCell.Value = stu.Mail
37    }
38    err = file.Save(outFile)
39    if err != nil {
40        fmt.Printf(err.Error())
41    }
42    fmt.Println("\n\nexport success")
43}
44func getStudents()[]Student{
45    students := make([]Student, 0)
46    for i := 0; i < 10; i++{
47        stu := Student{}
48        stu.Name = "name" + strconv.Itoa(i + 1)
49        stu.Mail = stu.Name + "@chairis.cn"
50        stu.Phone = "1380013800" + strconv.Itoa(i)
51        stu.age = 20
52        stu.Gender = "男"
53        students = append(students, stu)
54    }
55    return students
56}

代码执行结果如下：
