Scrapy’s Splash library renders JavaScript, making it easier to handle pages that rely heavily on AJAX for content.

If the PDFs follow a specific structure, regex helps isolate specific data fields like names, dates, or amounts from the raw text.

I sometimes find it helpful to group similar data fields, such as phone numbers or names, for bulk formatting and error-checking.

Combining searches with user-agent changes can sometimes bypass limitations, especially on mobile vs. desktop versions of a site.

I also use local storage as a temporary buffer, then upload the data in batches to cloud storage. This method reduces network load during scraping.
