golang mapping between xlsx and struct instances.

本库提供高层golang的struct切片和excel文件的映射,避免直接处理底层sheet/row/cells等细节。

本库底层使用unioffice,其提供了比360EntSecGroup-Skylar/excelize更加友好的API。

还有另外一个比较活跃的底层实现tealeg/xlsx尚未认证。

Usage documentation

Directly write excel file

package main

import "github.com/Han-Ya-Jun/xlsx"

type memberStat struct {
	Total     int `title:"会员总数" sheet:"会员"` // sheet可选,不声明则选择首个sheet页读写
	New       int `title:"其中:新增"`
	Effective int `title:"其中:有效"`
}

func main() {
	x, _ := xlsx.New()
	defer x.Close()

	x.Write([]memberStat{
			{Total: 100, New: 50, Effective: 50},
			{Total: 200, New: 60, Effective: 140},
		})
	x.SaveToFile("testdata/test1.xlsx")
}

you will get the result excel file as the following:

Write excel with template file

x, _ := xlsx.New(xlsx.WithTemplate("testdata/template.xlsx"))
defer x.Close()

x.Write([]memberStat{
        {Total: 100, New: 50, Effective: 50},
        {Total: 200, New: 60, Effective: 140},
    })
x.SaveToFile("testdata/test1.xlsx")

you will get the result excel file as the following:

Read excel with titled row

var memberStats []memberStat

x, _ := xlsx.New(xlsx.WithExcel("testdata/test1.xlsx"))
defer x.Close()

if err := x.Read(&memberStats); err != nil {
	panic(err)
}

assert.Equal(t, []memberStat{
	{Total: 100, New: 50, Effective: 50},
	{Total: 200, New: 60, Effective: 140},
}, memberStats)

create data validation

  1. Method 1: use template sheet to list the validation datas like:

image

then declare the data validation tag dataValidation like:

type Member struct {
	Area      string `title:"区域" dataValidation:"Validation!A1:A3"`
	Total     int    `title:"会员总数"`
	New       int    `title:"其中:新增"`
	Effective int    `title:"其中:有效"`
}
  1. Method 2: directly give the list in tag dataValidation with comma-separated like:
type Member struct {
	Area      string `title:"区域" dataValidation:"A,B,C"`
	Total     int    `title:"会员总数"`
	New       int    `title:"其中:新增"`
	Effective int    `title:"其中:有效"`
}
  1. Method 3: programmatically declares and specified the key name in the tag dataValidation like:
type Member struct {
	Area      string `title:"区域" dataValidation:"areas"`
	Total     int    `title:"会员总数"`
	New       int    `title:"其中:新增"`
	Effective int    `title:"其中:有效"`
}

func demo() {
	x, _ := xlsx.New(xlsx.WithValidations(map[string][]string{
		"areas": {"A23", "B23", "C23"},
	}))
	defer x.Close()

	_ = x.Write([]memberStat23{
		{Area: "A23", Total: 100, New: 50, Effective: 50},
		{Area: "B23", Total: 200, New: 60, Effective: 140},
		{Area: "C23", Total: 300, New: 70, Effective: 240},
	})

	_ = x.SaveToFile("result.xlsx")
}

占位模板

站位模板写入

image

type RegisterTable struct {
	ContactName  string    `asPlaceholder:"true"` // 联系人
	Mobile       string    // 手机
	Landline     string    // 座机
	RegisterDate time.Time // 登记日期
	DeviceType   string    `placeholderCell:"C8"` // 类型
	Manufacturer string    // 生产厂家
	DeviceModern string    // 型号
}

func demo() {
	x, _ := xlsx.New(xlsx.WithTemplate("testdata/placeholder.xlsx"))
	defer x.Close()

	_ = x.Write(RegisterTable{
		ContactName:  "隔壁老王",
		Mobile:       "1234567890",
		Landline:     "010-1234567890",
		RegisterDate: time.Now(),
		DeviceType:   "A1",
		Manufacturer: "来弄你",
		DeviceModern: "X786",
	})

	_ = x.SaveToFile("testdata/out_placeholder.xlsx")
}

占位模板读取

占位符模板读取,需要两个文件:

  1. “占位符模板”excel文件
  2. “待读取数据”excel文件

然后从“占位符模板”里获取占位符的位置,用这个位置信息,去实际“待读取数据”的excel文件中提取数据。

type RegisterTable struct {
	ContactName  string    `asPlaceholder:"true"` // 联系人
	Mobile       string    // 手机
	Landline     string    // 座机
	RegisterDate time.Time // 登记日期
	DeviceType   string    `placeholderCell:"C8"` // 类型,直接从C8单元格读取
	Manufacturer string    // 生产厂家
	DeviceModern string    // 型号
}

func demo() error {
	x, err := xlsx.New(
        xlsx.WithTemplate("testdata/placeholder.xlsx"), // 1. “占位符模板”excel文件
		xlsx.WithExcel("testdata/out_placeholder.xlsx"))     // 2. “待读取数据”excel文件
	if err != nil {
		return err
	}

	defer x2.Close()

	var v RegisterTable

	err = x2.Read(&v)
	if err != nil {
		return err
	}
}

Options

  1. asPlaceholder:"true" 使用“占位符模板”excel文件,从“占位符模板”里获取占位符的位置,用这个位置信息,去实际“待读取数据”的excel文件中提取数据。
  2. ignoreEmptyRows:"false" 读取excel时,是否忽略全空行(包括空白),默认true
