Web scraping refers to extracting data from a website

Although web scraping can be done manually, in most cases, automated tools are preferred when extracting web data because they are less expensive and operate at a faster rate.

But in most cases, web scraping is not a simple task. Websites come in a variety of shapes and forms, so web scrapers vary in functionality and features.

How Does Web Scraper Work?

Automatic web scraper works in a fairly simple but very complicated way. After all, websites are built for people to understand, not machines.

First, the web scraper will be provided with one or more URLs to load before extracting data. The scraper will then load the entire HTML code for the page in question. The more advanced scraper will render the entire site, including CSS and Javascript elements.

The scraper will then extract all the data on the page or the specific data selected by the user before running the project.

Ideally, users will go through the process of selecting the specific data they want from the page. For example, you might want to extract an Amazon product page for pricing and design, but you don't necessarily have to care about product reviews.

Finally, the web scraper will output all collected data into a more useful format for users.

Most web scraper will export data to CSV or Excel spreadsheet, while more advanced scraper will support other formats like JSON, which can be used for API.
