Should you do it yourself
This is what a basic DIY web scraping process looks like:

Determine the target website
Collect URLs of the pages where you need to extract data from
Make a request to those URLs to get the HTML of the web page
Use locators to seek out the data in the HTML
Save the data in a JSON or CSV file or some other structured format
