如何使用Python从Excel中读取和提取数据，并将其粘贴到文本文件中的现有文本中？

import openpyxl

workbook = openpyxl.load_workbook('文件路径/文件名.xlsx')
sheet = workbook['工作表名']

data = []
for row in sheet.iter_rows(min_row=2, values_only=True):
    data.append(row)

with open('目标文本文件路径/文件名.txt', 'r') as file:
    existing_text = file.read()

extracted_data = '\n'.join(['\t'.join(map(str, row)) for row in data])

new_text = existing_text + '\n' + extracted_data

with open('目标文本文件路径/文件名.txt', 'w') as file:
    file.write(new_text)
