XAV JSON to Primitives

Every other node in this pack moves opaque references around - the json_ref outputs are just UUID handles into an in-memory cache, not data you can use. This is the one that turns the handle back into something ComfyUI's normal nodes understand: an integer, a float, a boolean, a string. Loaded a config and want its value in a text encoder, a seed slot, or a filename token? This is your exit ramp.

One input: json_ref. Four outputs, all derived from the same underlying object: int_val, float_val, bool_val, str_val. The casting is blunt, straight from the source: int(obj) and float(obj) with a fallback to 0 / 0.0 when conversion fails; a bool that handles None → False, treats the strings "true", "1", "yes" (case-insensitive) as True, and otherwise just calls bool(obj); and str_val which is plain str(obj).

What that actually produces:

• A ref pointing at the number 5 → 5, 5.0, True, "5".
• A ref pointing at the string "42" → 42, 42.0, but False for the bool - "42" isn't in the true-list. Cute, and exactly the kind of thing that confuses people.
• A ref pointing at a nested object → 0, 0.0, True, and a str_val that looks like {'a': 1}.

That last one is the trap worth remembering: str() of a dict gives you Python's repr, not valid JSON. If you need actual JSON text out of an object, use XAV Save JSON to File instead - this node is for leaves, not trees.

Wire whichever output you need. The classic moves: str_val into a CLIP Text Encode or any string input, int_val or float_val into a seed or a size slot, bool_val into a switch or toggle. The outputs that don't fit what's stored just come back 0 / 0.0 / False with no error - convenient, and also a great way to silently feed a bad number downstream. If a seed suddenly reads 0, the ref was probably pointing at nothing, or you asked for an int from a value that isn't one.

This node is also the pack's answer to a complaint you'll hit the moment you start editing JSON: XAV Set JSON Value stores everything you type as a string. Set a key to 5 and the object holds "5". Convert it here and the wire going forward carries a real integer 5 - the stored value stays a string, but the output is typed. That alone is worth wiring this node in before anything that cares about numbers.

Install is painless because this pack is pure Python stdlib - zero dependencies, nothing to download. ComfyUI Manager → Install Custom Nodes → search "ComfyUI XAV JSON Nodes", or:

cd ComfyUI/custom_nodes
git clone https://github.com/XAV-Games/ComfyUI-XAVJsonNodes

Then restart ComfyUI. All seven nodes live under Add Node → XAV/json.
