ComfyUI Node: Save JSON

Save JSON:

The LF_SaveJSON node is designed to save JSON data to a specified file path, making it a valuable tool for AI artists who need to store and manage JSON data efficiently. This node allows you to specify the file path and filename for saving the JSON data, with an option to add a timestamp to the filename, ensuring unique and organized file storage. By automating the process of saving JSON data, this node helps streamline workflows and ensures that data is stored in a structured and accessible manner.

Save JSON Input Parameters:

json_data

This parameter represents the JSON data that you want to save. It accepts a JSON object and is required for the node to function. The JSON data can contain any structured information that you need to store, such as configuration settings, metadata, or other relevant data.

filepath

This parameter specifies the path and filename where the JSON data will be saved. It accepts a string value and allows you to define the directory structure using slashes. The default value is an empty string, and you can customize it to suit your file organization needs. For example, you can specify a path like data/output/myfile to save the JSON file in a specific directory.

add_timestamp

This boolean parameter determines whether a timestamp should be added to the filename as a suffix. The default value is True, which means a timestamp will be appended to the filename, ensuring that each saved file has a unique name. If set to False, the JSON file will be saved without a timestamp. This option is useful for maintaining version control and avoiding file overwrites.

Save JSON Output Parameters:

None

This node does not produce any output parameters. Its primary function is to save the provided JSON data to the specified file path.

Save JSON Usage Tips:

• Ensure that the filepath parameter is correctly specified to avoid saving files in unintended locations. Use clear and descriptive filenames to make it easier to identify the saved JSON files.
• Utilize the add_timestamp parameter to maintain a history of saved files, which can be helpful for version control and tracking changes over time.
• Verify that the directory specified in the filepath exists or can be created by the node to prevent errors during the file-saving process.

Save JSON Common Errors and Solutions:

Directory creation failed

• Explanation: This error occurs when the node is unable to create the specified directory for saving the JSON file.
• Solution: Ensure that you have the necessary permissions to create directories in the specified path. Check for any typos or invalid characters in the filepath parameter.

Invalid JSON data

• Explanation: This error occurs when the provided json_data is not a valid JSON object.
• Solution: Verify that the json_data parameter contains a properly formatted JSON object. Use tools or libraries to validate the JSON structure before passing it to the node.

File write error

• Explanation: This error occurs when the node is unable to write the JSON data to the specified file.
• Solution: Ensure that the filepath parameter is correctly specified and that you have write permissions for the target directory. Check for any issues with the file system, such as disk space limitations or file locks.
