Python – 调用接口合并文件夹下多个Excel表

在工作中经常遇到需要打开许多个excel表格，然后合并的需求，合并的同时要求格式必须原汁原味的保留。利用VBA代码可以比较轻松的解决，现在我们来看Python中如何实现。

上代码：

from openpyxl import Workbook
from win32com.client import Dispatch
import os
import datetimedef copy_excel_file(source_file_list, destination_file):
    run_app = Dispatch('Excel.Application')
    run_app.Visible = False  # 改为True可以看到excel的打开窗口    for file in source_file_list:
        source_workbook = run_app.Workbooks.Open(Filename=file)
        destination_workbook = run_app.Workbooks.Open(Filename=destination_file)        source_workbook.Worksheets(1).Copy(Before=destination_workbook.Worksheets(1))
        destination_workbook.Close(SaveChanges=True)    run_app.Quit()class ParameterGenerator:    def __init__(self):
        # self.directory_path = directory_path
        self.file_lists = []    def creat_xlsx(self, directory_path):
        obj = Workbook()
        if not os.path.exists(directory_path + os.sep + 'joined'):
            os.mkdir(directory_path + os.sep + 'joined')
        date = str(datetime.datetime.today())[0:10]
        obj.save(directory_path + os.sep + 'joined' + os.sep + 'joined {}.xlsx'.format(date))    def get_file_list(self, directory_path):
        entry_lists = os.scandir(directory_path)
        for entry_list in entry_lists:
            if entry_list.is_file():
                if '~$' not in entry_list.path:
                    self.file_lists.append(entry_list.path)
        return self.file_lists    def run(self, directory_path):
        file_lists = self.get_file_list(directory_path)
        self.creat_xlsx(directory_path)
        destination_file = str(self.get_file_list(directory_path + os.sep + 'joined')[-1])
        file_lists.pop(-1)
        return file_lists, destination_fileif __name__ == "__main__":
    directory_path = r'D:\Excel目录'
    param = ParameterGenerator()
    source_file_list, destination_file = param.run(directory_path)
    copy_excel_file(source_file_list, destination_file)
