I know, it’s easy for a programmer to build a web crawler to get data online. For those who barely know coding knowledge, how to get wanted data?
For me, I do know some web scraping tools, like Octoparse, Import.io, and Mozenda that can help us with getting data. However, what are the differences between a crawler that is coded by a programmer and a scrapper that is built with a tool?
Looking for an answer.
Thanks in advance.
