使用openpyxl将数据写入现有的Excel工作表

一般来说,我对编码很不满意.

我想要实现的是制作一个脚本,该脚本运行到excel中的雇主列表,每周生成一个新的小时表.通过为每个雇主生成一个空的小时表并重命名它,并在新制作的副本中更改周数和雇主名称.

我没有开始循环,因为我首先想要改变雇主姓名和周数的部分.我已经在互联网上搜索了一些答案,但我无法让代码工作,不断收到错误消息.

所以这是我的代码到目前为止：

import os
import shutil
import time
from openpyxl import load_workbook

#calculate the year and week number
from time import strftime
year = (time.strftime("%Y"))
week = str(int(time.strftime("%W"))+1)
year_week = year + "_" + week

#create weekly houresheets per employer
employer = "Adam"
hsheets_dir = "C:\\test\\"
old_file_name = "blanco.xlsx"
new_file_name = employer + "_" + year_week + ".xlsx"
dest_filename = (hsheets_dir + new_file_name)

shutil.copy2((hsheets_dir + old_file_name), dest_filename)

#change employer name and weeknumber
def insert_xlsx(dest, empl, wk):
    #Open an xlsx for reading
    print (dest)
    wb = load_workbook(filename = dest)
    #Get the current Active Sheet
    ws = wb.get_sheet_by_name("Auto")
    ws.cell(row=1,column=2).value = empl
    ws.cell(row=2,column=2).value = wk
    wb.save(dest)

insert_xlsx(dest_filename, employer, week_str)

以下是我不断收到的错误消息：

    "cannot serialize %r (type %s)" % (text, type(text).__name__)

有人会把我放在正确的方向吗？

非常感谢

解决方法:

我认为根据您的回答,问题在于您现有的小时表Excel电子表格：

>尝试从现有电子表格的副本开始并删除所有条目.希望这也会奏效.
>如果失败,请从新的空白电子表格开始.
>逐位复制现有数据并重复您的脚本.

通过这样做,您可能能够隔离与openpyxl不兼容的功能.

或者,您可以从Python脚本中编写所有内容,并跳过尝试修改半填充的脚本.这将是100％兼容的.
