Then the scraper obtains the required data from this HTML code and outputs this data in the format specified by the user. Then it loads all the HTML code for those sites and a more advanced scraper might even extract all the CSS and Javascript elements as well. So, when a web scraper needs to scrape a site, first the URLs are provided. For example, you might want to scrape an Amazon page for the types of juicers available, but you might only want the data about the models of different juicers and not the customer reviews. Ideally, it’s best if you specify the data you want so that the web scraper only extracts that data quickly. Web Scrapers can extract all the data on particular sites or the specific data that a user wants. The design of the scraper can vary greatly according to the complexity and scope of the project so that it can quickly and accurately extract the data.

The crawler is an artificial intelligence algorithm that browses the web to search for the particular data required by following the links across the internet. Web scraping requires two parts, namely the crawler and the scraper. In that situation, it’s best to use Web Scraping to scrape the website for data. This is the best option, but there are other sites that don’t allow users to access large amounts of data in a structured form or they are simply not that technologically advanced. have API’s that allow you to access their data in a structured format. Many large websites, like Google, Twitter, Facebook, StackOverflow, etc. These include using online services, particular API’s or even creating your code for web scraping from scratch. There are many different ways to perform web scraping to obtain data from websites. Most of this data is unstructured data in an HTML format which is then converted into structured data in a spreadsheet or a database so that it can be used in various applications. Web scraping is an automatic method to obtain large amounts of data from websites. So let’s understand what Web scraping is in detail and how to use it to obtain data from other websites.
