Item Relation/Inheritance Tree
Item Relation Tree detailing how SPT-AKI/EFT (as of 3.7.6) parented each and every items in the game according to the "ID" within the /template/items.json file.
The generation method will be included in a later update.
It's also sorted alphabetically. You are welcome.
The names are unfortunately not exactly the ones you could use to find them in Tarkov Item Finder, but with a hashtable of ID of all the items, it should be easy enough to find anything you want.
Please note: Wooden Ammo Box has a default name "Ammo Box" conflicting with another item in the list, so "Wooden Ammo Box" is used instead. (this is from locale/en.json)

And why wouldn't I just provide that information right here:

Happy modding!
