main.go文件：

package main

import (
	"fmt"
	"github.com/xuri/excelize/v2"
)

func main() {
	read() // 读excel文件
	//write()        // 写excel文件
	//readAndWrite() // 读写excel文件
}

func read() {
	f, err := excelize.OpenFile("read.xlsx")
	if err != nil {
		fmt.Println("excelize.OpenFile err: ", err)
		return
	}

	defer func() {
		if err := f.Close(); err != nil {
			fmt.Println("excelize.CloseFile err: ", err)
		}
	}()

	sheet := "Sheet1"
	rows, err := f.GetRows(sheet)
	if err != nil {
		fmt.Println("f.GetRows err: ", err)
		return
	}

	// 获取某一单元格
	a1, err := f.GetCellValue(sheet, "A1")
	fmt.Printf("A1:%s,err:%v\n", a1, err)

	fmt.Println()

	// 遍历所有行列
	for i, row := range rows {
		if len(row) <= 1 {
			break
		}
		fmt.Printf("%d\t%s\t%s\t%s\n", i, row[0], row[1], row[2])
	}

	fmt.Println()

	// 遍历所有行列
	for i, row := range rows {
		for j, cell := range row {
			fmt.Printf("rows[%d][%d]=%s\t", i, j, cell)
		}
		fmt.Println()
	}
}

func write() {
	f := excelize.NewFile()

	defer func() {
		if err := f.Close(); err != nil {
			fmt.Println("excelize.CloseFile err: ", err)
		}
	}()

	sheet1 := "Sheet1"
	sheet2 := "Sheet2"
	index, err := f.NewSheet(sheet2)
	if err != nil {
		fmt.Println("f.NewSheet err: ", err)
		return
	}

	f.SetCellValue(sheet1, "A1", "a")
	f.SetCellValue(sheet1, "B2", "b")
	f.SetCellValue(sheet1, "C3", "c")

	f.SetCellValue(sheet2, "A3", "a")
	f.SetCellValue(sheet2, "B2", "b")
	f.SetCellValue(sheet2, "C1", "c")

	f.SetActiveSheet(index)

	if err := f.SaveAs("write.xlsx"); err != nil {
		fmt.Println("excelize.SaveAs err: ", err)
	}
}

func readAndWrite() {
	f, err := excelize.OpenFile("read_and_write.xlsx")
	if err != nil {
		fmt.Println("excelize.OpenFile err: ", err)
		return
	}

	defer func() {
		if err := f.Close(); err != nil {
			fmt.Println("excelize.CloseFile err: ", err)
		}
	}()

	sheet := "Sheet1"
	rows, err := f.GetRows(sheet)
	if err != nil {
		fmt.Println("f.GetRows err: ", err)
		return
	}

	// 遍历所有行列
	for _, row := range rows {
		if len(row) <= 1 {
			break
		}
		fmt.Println(row)
	}

	// 添加数据
	f.SetCellValue(sheet, "D1", "备注")
	f.SetCellValue(sheet, "D2", "test")

	if err = f.Save(); err != nil {
		fmt.Println("excelize.SaveAs err: ", err)
	}
}

go.mod文件：

module excel-demo

go 1.23.0

require (
	github.com/mohae/deepcopy v0.0.0-20170929034955-c48cc78d4826 // indirect
