How does web scraping work?
A program opens a page, finds the elements that hold the data and copies their text or numbers into rows. Large crawlers discover pages on their own. A smaller approach reads only a list of pages you already have, in your own browser. See read values from web pages into a CSV and check prices from a list of URLs.
Is web scraping allowed?
It depends. A site’s terms may forbid automated reading, copyright and database rights can apply, and data-protection law such as the GDPR applies when the pages hold personal data. Where a site offers an official export, a feed or an API, use it. This is general information, not legal advice; ask a lawyer about your case.
