更新時(shí)間：2025年07月20日 10:43:04 作者：魚丸丶粗面

本文介紹了使用Python的openpyxl庫進(jìn)行Excel文件的創(chuàng)建、讀寫、數(shù)據(jù)操作、工作簿與工作表管理,包括創(chuàng)建工作簿、加載工作簿、操作Sheet、追加數(shù)據(jù)、查詢與修改單元格等內(nèi)容,需要的朋友可以參考下

1 概述

1.1 圖示

1.2 安裝第三方庫

pip install openpyxl

2 工作簿 workbook

2.1 創(chuàng)建：Workbook()

import openpyxl


class Excel(object):
    def __init__(self):
        pass

    def create_workbook(self, filename):
        """
        創(chuàng)建工作簿對象：workbook
        :param filename: 文件名（相對路徑 或 絕對路徑）
        :return:
        """
        # 1.聲明 工作簿 對象
        workbook = openpyxl.Workbook()

        # 2.保存 工作簿（若已存在，則覆蓋）
        workbook.save(filename)


if __name__ == '__main__':
    test = Excel()
    # C:\Users\Administrator\Desktop\Temp\1.xlsx
    test.create_workbook('1.xlsx')

2.2 常用屬性：load_workbook()

import openpyxl


class Excel(object):
    def __init__(self):
        pass

    def load_workbook(self, filename):
        # 1.獲取工作簿對象（獲取屬性前，先要加載工作簿）
        workbook = openpyxl.load_workbook(filename)

        # 2.查看工作簿支持的方法和屬性
        # print(help(workbook))

        # 3.常用的屬性
        print(f'active: {workbook.active}')  # 當(dāng)前活動的 sheet 頁
        print(f'read_only: {workbook.read_only}')  # 是否以只讀方式打開
        print(f'encoding: {workbook.encoding}')  # 編碼
        print(f'properties: {workbook.properties}')  # 屬性類，如：標(biāo)題、作者、創(chuàng)建日期 等
        # 單個(gè)的屬性信息，可通過下列形式 "." 出來
        print(f'title: {workbook.properties.title}')  # 標(biāo)題
        print(f'creator: {workbook.properties.creator}')  # 作者
        print(f'created: {workbook.properties.created}')  # 創(chuàng)建日期


if __name__ == '__main__':
    test = Excel()
    # C:\Users\Administrator\Desktop\Temp\1.xlsx
    test.load_workbook('1.xlsx')

2.3 獲取 sheet

import openpyxl


class Excel(object):
    def __init__(self, filename):
        self.workbook = openpyxl.load_workbook(filename)

    def get_sheets(self):
        # 1.獲取 sheet 列表
        print(self.workbook.sheetnames)  # 如：['Sheet', 'Sheet1']
        print(self.workbook.worksheets)  # 如：[<Worksheet "Sheet">, <Worksheet "Sheet1">]
        # print(self.workbook.get_sheet_names())  # deprecated function 已棄用

        # 2.獲取單個(gè) sheet
        print('------------')
        print(self.workbook['Sheet'])  # 根據(jù)名稱
        print(self.workbook.sheetnames[0])  # 根據(jù)下標(biāo)，如：Sheet
        print(self.workbook.worksheets[0])  # 根據(jù)下標(biāo)，如：<Worksheet "Sheet">


if __name__ == '__main__':
    test = Excel('1.xlsx')
    # C:\Users\Administrator\Desktop\Temp\1.xlsx
    test.get_sheets()

2.4 創(chuàng)建 sheet

class Excel(object):
    def __init__(self, filename):
        self.workbook = openpyxl.load_workbook(filename)
        self.filename = filename

    def create_sheet(self):
        # 1.末尾追加
        self.workbook.create_sheet('Sheet3')

        # 2.指定位置添加（index 從 0 開始，默認(rèn)末尾）
        self.workbook.create_sheet('Sheet4', 0)

        # 3.注意：若 Sheet 已存在，會默認(rèn)在名稱后面追加數(shù)字，如：Sheet31、Sheet32
        self.workbook.create_sheet('Sheet3')

        # 4.保存（只有保存后，才會生效哦）
        self.workbook.save(self.filename)


if __name__ == '__main__':
    test = Excel('1.xlsx')
    # C:\Users\Administrator\Desktop\Temp\1.xlsx
    test.create_sheet()

    def __init__(self, filename):
        self.workbook = openpyxl.load_workbook(filename)
        self.filename = filename

    def copy_sheet(self):
        # 1.獲取 sheet 對象
        sheet = self.workbook['Sheet']

        # 2.復(fù)制 sheet（默認(rèn)名稱 + copy，如：Sheet Copy）
        self.workbook.copy_worksheet(sheet)

        # 3.保存（只有保存后，才會生效哦）
        self.workbook.save(self.filename)


if __name__ == '__main__':
    test = Excel('1.xlsx')
    # C:\Users\Administrator\Desktop\Temp\1.xlsx
    test.copy_sheet()

        # 1.刪除 sheet
        del self.workbook['Sheet Copy']

        # 2.保存后生效
        self.workbook.save(self.filename)

        # 1.移動 sheet（負(fù)數(shù)=向左移動、正數(shù)=向右移動、數(shù)值=移動位置的個(gè)數(shù)）
        self.workbook.move_sheet('Sheet', -1)

        # 2.保存后生效
        self.workbook.save(self.filename)
