To start with, the web scrubber will be given at least one URL to stack prior to scratching. The scrubber loads the whole HTML code of the page being referred to. Further developed scrubbers will deliver the whole site including CSS and JavaScript components.
The scraper will then either delete all the data on the page or specific data selected by the user before the project is run.
Ideally, the user will go through the process of selecting the specific data they want from the page. For example, you may want to scour an Amazon product page for prices and models but are not necessarily interested in product reviews.
Finally, the web scraper will output all the data collected in a more useful format for the user.
Most web scrapers will output data to a CSV or Excel spreadsheet, while more advanced scrapers will support other formats such as JSON, which can be used for APIs.
