Web scraping, also known as web data extraction, is the process of retrieving or “scraping” data from a website. web scraping uses intelligent automation to retrieve hundreds, millions, or even billions of data points from the internet.
It’s extremely simple, in truth, and works by way of two parts: a web crawler and a web scraper. The web crawler is the horse, and the scraper is the chariot. The crawler leads the scraper, as if by the hand, through the internet, where it extracts the data requested.
