python - 使用 openpyxl 将数据写入现有的 Excel 工作表

总的来说，我对编码很陌生。

我想要实现的是制作一个脚本，该脚本运行到 excel 中的雇主列表并每周生成一个新的小时表。通过为每个雇主生成一份空白的工作表并重命名，并在新制作的副本中更改周数和雇主名称。

我没有从循环开始，因为我首先想制作更改雇主名称和周数的部分。我已经在互联网上搜索了一些答案，但我无法使代码正常工作，不断收到错误消息。

所以这是我到目前为止的代码:

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)

这是我不断收到的错误消息:

    "cannot serialize %r (type %s)" % (text, type(text).__name__)
TypeError: cannot serialize 3 (type int)

有人可以把我放在正确的方向吗？

非常感谢

最佳答案

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。希望这也能奏效。

如果此操作失败，请从一个新的空白电子表格开始。

一点一点地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 脚本中编写整个内容，并跳过尝试修改半填充的内容。这将是 100% 兼容的。
