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。
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:
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:
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)
- Method 1: use template sheet to list the validation datas like:
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"`
}
- 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"`
}
- 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")
}
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")
}
占位符模板读取,需要两个文件:
- “占位符模板”excel文件
- “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
}
}
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。ignoreEmptyRows:"false"
读取excel时,是否忽略全空行(包括空白),默认true
