Download the file in this link that matches your operating system, unzip it, and run bspsrc.bat.
You can input a bsp file via 'add' and convert it to a vmf file via 'decompile'.
Open In Hammer editor

Visgroups

The recommended visgroup configuration for map analysis is to check only Point Entities, Brush Entities, and Game Logic.
