ComfyUI Node: Load JSON from disk

Load JSON from disk:

The LF_LoadLocalJSON node is designed to load JSON data from a local file into your workflow. This node is particularly useful when you need to incorporate structured data stored in JSON format into your AI art projects. By specifying the local URL of the JSON file, the node reads the file and makes its contents available for further processing. This can be beneficial for tasks such as configuring parameters, feeding data into other nodes, or dynamically adjusting your workflow based on the JSON content. The primary goal of this node is to streamline the integration of local JSON data, making it accessible and usable within your creative pipeline.

Load JSON from disk Input Parameters:

url

The url parameter specifies the local URL where the JSON file is stored. This should be a string formatted as file://<path_to_your_json_file>. For example, file://C:/myjson.json`. This parameter is essential as it tells the node where to find the JSON file to be loaded. The default value is an empty string, and it supports multiline input for convenience. The tooltip for this parameter provides guidance on the expected format.

Load JSON from disk Output Parameters:

JSON

The output of the LF_LoadLocalJSON node is a JSON object. This JSON object contains the data read from the specified local file. The output can be used in subsequent nodes to drive various aspects of your workflow, such as setting parameters, generating content, or making decisions based on the JSON data.

Load JSON from disk Usage Tips:

• Ensure the file path is correctly formatted as file://<path_to_your_json_file> to avoid errors in locating the file.
• Use this node to load configuration settings or data that can dynamically influence your AI art generation process.
• Combine this node with other JSON processing nodes to manipulate and utilize the loaded data effectively.

Load JSON from disk Common Errors and Solutions:

FileNotFoundError

• Explanation: The specified file path does not exist or is incorrect.
• Solution: Verify that the file path is correct and that the file exists at the specified location. Ensure the path is formatted as file://<path_to_your_json_file>.

json.JSONDecodeError

• Explanation: The file content is not valid JSON.
• Solution: Check the JSON file for syntax errors and ensure it is properly formatted. Use a JSON validator to confirm the correctness of the file.

PermissionError

• Explanation: The node does not have permission to read the specified file.
• Solution: Ensure that the file permissions allow reading by the application. Adjust the file permissions if necessary.

Unexpected error: <error_message>

• Explanation: An unexpected error occurred during the execution of the node.
• Solution: Review the error message for clues about the issue. Check for common problems such as incorrect file paths, invalid JSON content, or permission issues. If the problem persists, consider seeking support with the detailed error message.
