Python实现excel表格合并

Posted 2021-10-05 小蜗牛爱远行

• 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:
          print("请重新启动程序并输入正确的操作代码")
          time.sleep(5)
