Quickstart

Get codes
$ go get github.com/miaomiao3/xlsxutil

Import
import ( "github.com/miaomiao3/xlsxutil" )

supposed a csv document content:

name,money,age,school,address
n-0,1.2345678900,20,school-0,hali-0
n-1,1.2345678900,21,school-1,hali-1
n-2,1.2345678900,22,school-2,hali-2
n-3,1.2345678900,23,school-3,hali-3
n-4,1.2345678900,24,school-4,hali-4

To bind this csv to out data, and dump data to csv string, just like

package main

import (
	"fmt"
	"github.com/miaomiao3/xlsxutil"
)

const (
	csvFilePath = "people.csv"
)

type Person struct {
	Name  string  `xls:"name"`
	Money float64 `xls:"money,precision:2"`
	Age   int     `xls:"age"`
	Edu   `xls:",inline"`
}

type Edu struct {
	School  string `xls:"school"`
	Address string `xls:"address"`
}

func main() {
	persons := make([]*Person, 0)
	err := xlsxutil.CsvLoad(csvFilePath, ",", &persons)
	if err != nil {
		panic(err)
	}
	fmt.Println("persons:", persons)

	buf, err := xlsxutil.CsvDump(",", persons)
	if err != nil {
		panic(err)
	}
	fmt.Println("buf")
	fmt.Println(buf)
}

terminal output:

$ go run main.go
persons: [0xc000078140 0xc000078180 0xc0000781c0 0xc000078200 0xc000078240]
buf
name,money,age,school,address
n-1,1.23,21,school-1,hali-1
n-2,1.23,22,school-2,hali-2
n-3,1.23,23,school-3,hali-3
n-4,1.23,24,school-4,hali-4
