Web scraping, web harvesting, or web data extraction is data scraping used for extracting data from websites.Web scraping a web page involves fetching it and extracting from it.Web scraping automatically extracts data and presents it in a format you can easily make sense of.Use of APIs being probably the best way to extract data from a website. Almost all large websites like Twitter, Facebook, Google, Twitter, StackOverflow provide APIs to access their data in a more structured manner.
