Data that is visible on the web page is not always accessible, and hidden data that exist in the HTML documents can reveal more valuable information most often. To make good use of the content posted on the web, we can first extract the data from the web for valid purposes, legally. This process is called web scraping, and the tool used during this data extraction is called web scraper. Usually we copy and paste web content manually if we don’t know programming, and using traditional web extraction methods are time consuming and inefficiency. Besides, most of the information on the website is written in different forms on the web - within a HTML tag or a HTML attribute. Therefore it’s better for non-programmers to use some web scraping software that can grab the exact content you want to pull out of the website and combine the data with your own system/database.
