无法使用 openpyxl 在 excel 文件中写入 html 内容

Question

I've created a tiny script in python to scrape the first title and it's description from a website and write the same in an excel file using openpyxl library. The important thing to notice here is that I wish to save the title as text but the description as raw html content, not text.

I've tried like:

import requests
from bs4 import BeautifulSoup
from openpyxl import Workbook

link = "https://stackoverflow.com/questions/tagged/web-scraping"
wb = Workbook()
wb.remove(wb['Sheet'])

def fetch_content(link):
    req = requests.get(link)
    soup = BeautifulSoup(req.text,"lxml")
    title = soup.select_one("#questions .summary .question-hyperlink").get_text(strip=True)
    desc = soup.select_one("#questions .summary")

    ws.append([title,desc])
    print(title,desc)

if __name__ == '__main__':
    ws = wb.create_sheet("output")
    ws.append(['Title','Description'])
    fetch_content(link)
    wb.save("SO.xlsx")

When I run the script, I get the following error:

raise ValueError("Cannot convert {0!r} to Excel".format(value))
ValueError: Cannot convert <div class="summary"> -----so on

Expected output in that excel file (both truncated):

How to scrape data   <div class="summary">

stovfl and robot.txt made the perfect solution. I took the liberty to post the answer since I often forget this approach.

def fetch_content(link):
    req = requests.get(link)
    soup = BeautifulSoup(req.text,"lxml")
    title = soup.select_one("#questions .summary .question-  hyperlink").get_text(strip=True)
    desc = soup.select_one("#questions .summary")

    ws.append([title,str(desc)]) #cast desc to str
    print(title,desc)
