To clarify, I don't manually keep points up to date. There's a script that reads the PDFs published on the warcom site. (well, not the pdf file but their raw text content) This makes it very easy to update points & datasheets, because all I need to do is copy&paste the new files.
I've looked into it and maybe... The formatting of wargear is ... inconsistent on the datasheets and creating a script that extracts useful data from them is challenging. like ... wtf is this 😂
It only does the list (which you can print, ctrl+P) I didn't personally find it useful to include the datasheets since those are freely available as a PDF. (also there might be copyright involved)
I created an easy to use list builder for 40K 10th edition

It supports all factions (including forge world) and lets you adjust which models are in your personal collection.
