##xlsx简介

A file with the XLSX file extension is a Microsoft Excel Open XML Format Spreadsheet file. It's an XML-based spreadsheet file created by Microsoft Excel version 2007 and later.

XLSX files organize data in cells that are stored in worksheets, which are in turn stored in workbooks, which are files that contain multiple worksheets. The cells are positioned by rows and columns and can contain styles, formatting, math functions, and more.

Microsoft Office EXCEL 2007/2010/2013/2016文档的扩展名。xlsx是从Office2007开始使用的，是用新的基于XML的压缩文件格式取代了其目前专有的默认文件格式，在传统的文件名扩展名后面添加了字母x（即：docx取代doc、.xlsx取代xls等等），使其占用空间更小。

有点excel基础的人，都应该清楚什么是sheet，什么是row，cell即内容。

####读取xlsx

package main

import (
	"fmt"

	"github.com/tealeg/xlsx"
)

func main() {
	excelFileName := "test.xlsx"
	xlFile, err := xlsx.OpenFile(excelFileName)
	if err != nil {
		fmt.Printf("open failed: %sn", err)
	}
	for _, sheet := range xlFile.Sheets {
		fmt.Printf("Sheet Name: %sn", sheet.Name)
		for _, row := range sheet.Rows {
			for _, cell := range row.Cells {
				text := cell.String()
				fmt.Printf("%sn", text)
			}
		}
	}
}

读取结果：

Sheet Name: Sheet1

姓名

年龄

狗子

蛋子

####创建xlsx

package main

import (
	"fmt"

	"github.com/tealeg/xlsx"
)

func main() {
	var file *xlsx.File
	var sheet *xlsx.Sheet
	var row, row1, row2 *xlsx.Row
	var cell *xlsx.Cell
	var err error

	file = xlsx.NewFile()
	sheet, err = file.AddSheet("Sheet1")
	if err != nil {
		fmt.Printf(err.Error())
	}
	row = sheet.AddRow()
	row.SetHeightCM(1)
	cell = row.AddCell()
	cell.Value = "姓名"
	cell = row.AddCell()
	cell.Value = "年龄"

	row1 = sheet.AddRow()
	row1.SetHeightCM(1)
	cell = row1.AddCell()
	cell.Value = "狗子"
	cell = row1.AddCell()
	cell.Value = "18"

	row2 = sheet.AddRow()
	row2.SetHeightCM(1)
	cell = row2.AddCell()
	cell.Value = "蛋子"
	cell = row2.AddCell()
	cell.Value = "28"

	err = file.Save("test_write.xlsx")
	if err != nil {
		fmt.Printf(err.Error())
	}
}

####修改xlsx

package main

import (
	"github.com/tealeg/xlsx"
)

func main() {
	excelFileName := "test.xlsx"
	xlFile, err := xlsx.OpenFile(excelFileName)
	if err != nil {
		panic(err)
	}
	first := xlFile.Sheets[0]
	row := first.AddRow()
	row.SetHeightCM(1)
	cell := row.AddCell()
	cell.Value = "铁锤"
	cell = row.AddCell()
	cell.Value = "99"

	err = xlFile.Save(excelFileName)
	if err != nil {
		panic(err)
	}
}
