Web scraping is the process or technique of extracting data or information from a website.The scraped or extracted data is collected and then exported into the human user friendly format.Is Web scraping legal?
To be honest, it depends upon the type of website. If the information or data is available publicly, then there should not be any restrictions for scraping it unless the website owner prohibits the practice of web scraping.
But on the other hand, if the data of the website is available only for a limited number of people or for a limited period of time then most probably scraping those websites without permission can be illegal.
