使用Python实现excel表格合并（程序打包：pyinstaller -F ***.py）：

• 一个excel文件的多sheet合并
• 文件夹下多个Excel文件的合并（单个文件的多sheet也会自动合并）

源码（仅供参考，个需自行修改）：

import tkinter as tk
from tkinter import filedialog
from datetime import datetime
import pandas as pd
import os, time, openpyxl, logging
from openpyxl import load_workbook

logging.basicConfig(level=logging.DEBUG,
                    format='%(asctime)s line:%(lineno)d %(levelname)s : %(message)s',
                    datefmt=' %Y-%m-%d %H:%M:%S',
                    filename='info.log',
                    filemode='a')


class Excel:

    def merge_sheets(self):
        wd = tk.Tk()
        wd.withdraw()
        print('*'*10 + '请选择需要合并的Excel' + '*'*10)
        excel_file = filedialog.askopenfilename()
        logging.info(excel_file)
        data_df = pd.DataFrame()
        data_df = self.merge(excel_file, data_df)
        data_df.to_excel(excel_file.split("/")[-1].split(".")[0] + "-new.xlsx", index=False)

    def merge_excels(self):
        wd = tk.Tk()
        wd.withdraw()
        print('*' * 10 + '请选择需要合并的文件夹' + '*' * 10)
        foldpath = filedialog.askdirectory()
        data_df = pd.DataFrame()
        for file_path in os.listdir(foldpath):
            data_df = self.merge(os.path.join(foldpath, file_path), data_df)
        data_df.to_excel("文件夹中表格合并结果.xlsx", index=False)

    def merge(self, excel_file, data_df):
        df = pd.read_excel(excel_file, sheet_name=None)
        sheet_names = [i for i in df.keys()]
        for sheet_name in sheet_names:
            read_df = pd.read_excel(excel_file, sheet_name=sheet_name)
            data_df = data_df.append(read_df)
        return data_df


if __name__ == '__main__':
    print('***************yyds的Excel程序正在运行***************')
    print("需要执行操作对应的代码：\n"
                   "\t1.合并一个Excel里面所有的sheet；\n"
                   "\t2.合并文件夹下所有的Excel")
    choose = input("请输入对应的编号：")
    excel = Excel()
    if choose == "1":
        excel.merge_sheets()
        print('*' * 10 + 'YYDS程序已经执行结束，请核对结果' + '*' * 10)
        time.sleep(5)
    elif choose == "2":
        excel.merge_excels()
        print('*' * 10 + 'YYDS程序已经执行结束，请核对结果' + '*' * 10)
        time.sleep(5)
    else:
