To understand all about data extraction we must take it as a technique or method of efficient data parsing from a website. It is time efficient and usage of its tools is quite easy as well. Scraping tools provide us with ease to parse data and all the required information from a website. Websites not available with API’s require some different methods for data extraction. We can also access data through this method if API is not there for us as well, but as compared to that data scraping API is something more worthy to deal with.
