How to access the built-in browser in the application?

Question

Parsing

Access to the browser built into the application.
There is a commercial application that displays a large amount of reference data in the form of tables with pagination and some filter. The application works via the Internet, requests values ​​from the server and displays them in a window.
As it turned out, the application shows information in the built-in browser, similar to IE (since these tables were found in the cache on disk). I really want to get this data in some kind of my database / Excel files.
Is there any way to make it happen? At the moment, the only thought is to take screenshots and recognize the data, but there are a lot of plates.
P.S. I know a little python
