ComfyUI JSON Helper

This custom node for ComfyUI provides a simple way to convert JSON strings to JSON objects, bridging the gap between nodes that output JSON as strings and nodes that require JSON object inputs.

Features

  • Converts JSON strings to JSON objects
  • Handles JSON parsing errors gracefully
  • Easy to integrate into existing ComfyUI workflows

Requirements

  • ComfyUI
  • Python 3.10+

Installation

  1. Navigate to your ComfyUI custom nodes folder: 
    cd /path/to/ComfyUI/custom_nodes/
  2. Clone this repository: 
    git clone https://github.com/a-und-b/ComfyUI-JSONHelper.git
  3. Restart ComfyUI

Usage

After installation, you'll find a new node called "JSON String to Object" in the node menu.

  1. Connect the output of a node that produces a JSON string to the input of this node.
  2. The output of this node will be a JSON object, which can be connected to nodes that expect JSON input.

Error Handling

If the input string is not valid JSON, the node will print an error message to the console and return None.
