Quick Example
Save Text Into JSON:
Very useful for batching a bunch of LLM VL outputs and saving them with the filename or path as a key for later use.
Save Text Into JSON
├─ key: "path/or/filename/or/any_string"
├─ value: "a beautiful sunset"
└─ file: "prompts/settings.json"
Load it back:
Load Text From JSON From Key
├─ key: "path/or/filename/or/any_string"
└─ file: "prompts/settings.json"
→ outputs: "a beautiful sunset"
File Location
All files save to: ComfyUI/output/{your-path}
Example: text/data.json → ComfyUI/output/text/data.json
