The Web Scraping Process - How Do Web Scrapers Work? What is data scraping? The process is to first give the scraper a Uniform Resource Locator (URL), which it then loads. The scraper loads all the HTML associated with that page. In the case of advanced web scrapers, they can render everything on the website, including JavaScript and Cascading Style Sheets (CSS) elements. The scraper then extracts data. It can be programmed to extract all data from the website or just what the user wants. In many cases, this means that the user has to provide certain data, and pricing information, which he wants to use for business intelligence. In the last step, the web scraper outputs the collected data so that the end user can use it. This can be in a CSV file or as an Excel spreadsheet. Some of the more advanced web scrapers can be output to other formats, such as JSON, which integrate with Application Programming Interfaces (APIs). How United Lead Scraper fulfill your needs and wor
