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
