有没有办法将整个Excel表格转换为pdf

Question

我正在尝试自动化办公室中的一项任务，其中我必须通过电子邮件手动向每个客户发送客户报表。我虽然可以使用 python 和 excel vba 自动执行此任务。 因此，在 Python 中，我正在获取一个包含所有客户端详细信息的文件，并为每个客户端在不同的文件中创建一个单独的选项卡，其中包含这些详细信息，其中宏以 xlsm 文件格式保存。之后，更新单元格中的客户编号并运行 Marco 以根据客户编号获取这些详细信息。在此阶段，在主选项卡中准备了一份声明。之后我尝试将主选项卡转换为 pdf 文件格式。下面是我的整个Python代码。

import pandas as pd
from openpyxl import load_workbook
import win32com.client



class Logic():

    old_unique_ids = {} # stores clientid of old and new vales as dict
    new_unique_ids = [] # query through excel and gets unique client ids


    def __init__(self,input_file,output_file,pdf_path):
        self.input_file = input_file 
        self.output_file = output_file 
        self.pdf_path = pdf_path 
        self.read_file = []


    def replace_forward_slash_with_hyphen(self):
        '''Replaces forward slash with hyphen and the before change client ids are saved in "old_unique_ids" '''
        workbook = load_workbook(self.input_file)
        for sheet_name in workbook.sheetnames:
            sheet = workbook[sheet_name]
            for row in sheet.iter_rows():
                for cell in row:
                    if isinstance(cell.value, str) and "/" in cell.value: # checks if any cell value has /
                        old_value = cell.value
                        cell.value = cell.value.replace("/", "-")
                        Logic.old_unique_ids[cell.value] = old_value # append old and new id to dict
        workbook.save(self.input_file)


    def get_unique_values(self):
        '''Gets unique value of new formated id and saves to new_unique_ids'''
        self.read_file = pd.read_excel(self.input_file)
        self.read_file['Date'] = self.read_file['Date'].dt.strftime('%d/%m/%y') # changes the data format in DF
        Logic.new_unique_ids = self.read_file['ClientID'].unique().astype(str) # gets unique values and stores in str




    def get_all_items(self):
        """loop through each id and get the detils from file and write the data to new excel file"""
        for id in Logic.new_unique_ids:
            data = self.read_file[(self.read_file['ClientID'] == id)] # loop and query through each id and get id details
            with pd.ExcelWriter(self.output_file,
                                engine='openpyxl',
                                mode='a',
                                engine_kwargs={"keep_vba": True},
                                if_sheet_exists='replace') as writer:
                
                data.to_excel(writer,  # Write data to excel in seperate tab
                                sheet_name = id,
                                index=False, 
                                startrow=0, 
                                header=True)

    
    def convertToPdf(self):
        excel = win32com.client.Dispatch("Excel.Application")
        excel.Visible = False
        excel.DisplayAlerts = False
        workbook_path = self.output_file
        workbook = excel.Workbooks.Open(workbook_path)
        ws = workbook.Sheets('Table') # Replace with with acutal sheet name
        for n in Logic.new_unique_ids:
            if len(Logic.old_unique_ids) != 0:
                for i, j in Logic.old_unique_ids.items():
                    if n == i:
                        ws.Range('D4').Value = j
                        break  # Exit the loop once a match is found
            else:
                ws.Range('D4').Value = n
            #excel.Run("proFirst")  # Replace with actual macro name
            workbook.Save()
            workbook.Close(SaveChanges=False)
            excel.Quit()
            o = win32com.client.Dispatch("Excel.Application")
            o.Visible = False
            o.DisplayAlerts = False
            workbook_path = self.output_file
            workbook = o.Workbooks.Open(workbook_path)
            workbook.Worksheets('Table').Select()
            pdf_file_path = f"{self.pdf_path}/{n}.pdf"
            workbook.ActiveSheet.ExportAsFixedFormat(0, pdf_file_path)

input_file = 'input.xlsx'
output_file = r"C:\Users\madha\OneDrive\Desktop\Testing\output.xlsm"
pdf_path = "C:/Users/Testing/files"

app = Logic(input_file = input_file,output_file = output_file,pdf_path = pdf_path)
app.replace_forward_slash_with_hyphen()
app.get_unique_values()
app.get_all_items()
app.convertToPdf()

一切工作正常，直到运行宏并在主选项卡中使用 Marco 创建语句，但是当我尝试将该语句转换为 PDF 时，我的代码总是出现如下错误

pywintypes.com_error: (-2147352567, '发生异常。', (0, 'Microsoft Excel', '文档未保存。文档可能已打开，或者保存时遇到错误。', 'xlmain11.chm ', 0, -2146827284), 无)

我不确定我哪里出错了，我尝试了不同的方法来完成这项工作，但仍然不起作用。

有没有更简单的方法来完成这项工作？

如果 Excel 文档当前在 Excel 中打开，则可能不允许您的脚本访问 Excel 文档。运行之前尝试关闭所有 Excel 实例。
