JSON Values to List

Documentation

• Class name: SaltJSONValuesToList
• Category: SALT/JSON
• Output node: False

This node is designed to extract the values from a JSON object and provide them in two formats: as a list and as a string with each value separated by a newline. It ensures that the input JSON is properly formatted and is a dictionary before proceeding with the extraction.

Input types

Required

• json_input
  • The JSON string input from which values are to be extracted. It must be a well-formed JSON dictionary. This input is crucial for the node's operation as it determines the source of the values to be processed.
  • Comfy dtype: STRING
  • Python dtype: str

Output types

• values
  • Comfy dtype: LIST
  • A list of values extracted from the input JSON dictionary.
  • Python dtype: List[Any]
• values_list
  • Comfy dtype: STRING
  • A string representation of the values extracted from the input JSON, separated by newlines.
  • Python dtype: str

Usage tips

• Infra type: CPU
• Common nodes: unknown
