将 .txt 导入现有 excel 到新工作表

Question

我完全沉浸在我正在进行的小项目中。我每月一次将数据从 .txt 文件导入现有的 excel。每次执行此操作时，我都想在 excel 中创建一个新工作表并将数据添加到其中，而不更改其他工作表中的任何内容。我的方法看起来像这样。

from datetime import date, timedelta
import pandas as pd
import numpy as np
import openpyxl
from openpyxl import load_workbook
import os


now = date.today()
last_month = now.month-1 if now.month > 1 else 12
last_year = now.year - 1

if last_month != 1:
filename = "0" + str(last_month) + "." + str(now.year) + ".txt"

else:
    filename = "12" + "." + str(last_year) + ".txt"

print(filename)

writer = pd.ExcelWriter("Ausgabenliste.xlsx", engine='openpyxl')


if os.path.exists("Ausgabenliste.xlsx"):
    book = openpyxl.load_workbook("Ausgabenliste.xlsx")
    writer.book = book
df = pd.read_csv(filename, sep=" ")
df.to_excel(writer, sheet_name=filename)
writer.save()
writer.close()

我总是收到以下错误消息：

感谢您的帮助。非常感谢。

这会向现有 XLSX 添加一个新工作表：

# Load existing 
book = load_workbook('x.xlsx')
writer = pd.ExcelWriter('x.xlsx', engine = 'openpyxl')
# Starting with the existing worksheets
writer.book = book
# Adding a new worksheet
df.to_excel(writer, sheet_name='gtomer')
writer.save()
