[1.19.4+] How to create NBT data (for items) from arbitrary NBT String or JSON input

[BlackJar72]

OK, what I need is to be able to take a JSON string, from a config file or data pack, and convert into NBT that can be applied to any arbitrary item (technically, item stack).

This could easily be done in 1.12.2 using JsonToNBT.getTagFromJson(String data) like so:

	NBTFromJsonWrapper(String label, String data) {
		super(label, label);
		try {
			wrapped = JsonToNBT.getTagFromJson(data);
		} catch (NBTException e) {
			System.err.println("Exception reading json-nbt string: " + e.getMessage());
			wrapped = new NBTTagCompound();
		}
	}

However, I can't seem to find a way to do this in newer version, specifically 1.19.4 (though once I'm done updating to that version I plan to be updating the latest 1.20 and 1.21 version).

Alternately, of these NBT strings that resemble JSON but are not quite would be just as good, perhaps better:

{ench:[{lvl:3s,id:35s},{lvl:5s,id:32s}],Unbreakable:1b,display:{Lore:["Believe it or not, this comes from ","an ancient Vanilla World. "],Name:"Fortuna Major"}}

This was previously used for several purposes, one was simply to create purely vanilla potions.  The other was to create special items, primarily as trophies albeit practically useful trophies, often in the form of Easter Eggs.

(I also had a homebrew system along side it, but I don't think I'll be updating it.)

Any help would be appreciated.  Surely there is still a way to do this, and codecs do not seem to be the answer.

Sorry to have bothered everyone.  I think I've figured it out:

NbtUtils.snbtToStructure() will allow me to get the compound tag from a string I can load, and ItemStack.setTag() will allow me to write it to an item.

Again, sorry to bother everyone -- it took a long time to work it out, it seems finding answers on the internet by googling isn't a viable way to get info so it took a lot of guessing, experimenting, and trial and error until I hit upon the path to a solution.
