With the continuous development of Internet technology, the acquisition and exchange of information have become more and more convenient, and the role of data in it has become increasingly prominent. Among them, Excel, as a common data processing tool, is widely used in various fields, such as financial analysis, business decision-making, scientific research, etc. However, many times we need to import data from web pages into Excel for further data processing, and at this time, HTML conversion to Excel becomes an essential tool.

1. What is HTML?

First of all, let us briefly understand HTML (HyperText Markup Language), which is hypertext markup language. It is a markup language used to create web pages. Through HTML, we can display text, images, audio, video, animation and other information on web pages. This information can be wrapped in different tags (tags), and the tags form the structure of the web page.

Many web pages have tabular data, such as product information, stock data, statistical reports, etc. The arrangement and format of these table data are implemented through HTML tags. However, if these data need to be further processed, such as calculations, statistics, chart analysis, etc., you need to use data processing tools such as Excel. The HTML to Excel conversion is to directly import the table data on the web page into Excel for processing, which is convenient, fast and improves efficiency.

The specific code is as follows:

import pandas as pd
from bs4 import BeautifulSoup
import requests

Web page path of table data

url = "https://example.com"

Request the web page for table data and get the HTML document

response = requests.get(url)

Use BeautifulSoup to parse the HTML document

soup = BeautifulSoup(response.content, "html.parser")

Get the table in the HTML document

tables = soup.find_all('table')

Convert table data to DataFrame format

df = pd.read_html(str(tables))[0]

Write DataFrame data to Excel file

writer = pd.ExcelWriter('result.xlsx')
df.to_excel(writer, 'Sheet1', index=False)
writer.save()
