Browser Dev Toolsĭev tools is possibly one of the very first thing that needs to be checked before writing actual code. □ This blog post uses Python as language to show code examples. Shown tips should be plenty enough to get you going or understand where to potentially look to solve the problem. □ Some of the techniques will not be mentioned intentionally in order not to disclose some of the methods we use. We want to share a little of our knowledge gained while building our APIs. With CRX Extractor, you’ll have a much easier time getting into that source code to study, learn, and replicate from the best developers out there.This ongoing blog post is about understanding ways of extracting data from any website, either if the website is static/fully JavaScript driven or if reverse engineering needs to be applied.Īfter this blog post, you can understand and apply this knowledge to create structured data from messy data from any website.Īt SerpApi we're extracting data from all sorts of websites and each one of them requires a specific approach that will able us to parse data fast and efficiently and most importantly without browser automation.
