How does it work?
All the job is carried out by a scraper, which is a piece of code.
In the first step, it sends a “get” code query to the website it wants to be scraped. It can be configured to work with any website, or it can be built for a specific website.
Then, web scraping software will automatically load and extract data from multiple pages of websites based on the requirement.
After this, it defines an HTML document based on the results of the query.
In the final step, the requested data is searched in the document by the scrapers and the results are converted in a document specified by the user before. With a simple click of a button, the data available on the website can be saved easily.
