For programmers, using Python scripts can achieve automated conversion of HTML files. Python provides the HTMLParser library, which can parse HTML tags into plain text format.

The following is an example Python script:

from html.parser import HTMLParser
class TxtConverter(HTMLParser):
    def __init__(self):
        super().__init__()

        self.text += data

html = open("example.html", "r").read()
txtConverter = TxtConverter()
txtConverter.feed(html)
