Documentation

  • Class name: LLMUnstructuredReader
  • Category: SALT/Language Toolkit/Readers
  • Output node: False

The LLMUnstructuredReader node is designed to read and process unstructured files, converting them into a format suitable for indexing and further analysis by the llama_index system. It supports a variety of file types, making it a versatile tool for ingesting raw data into structured document formats.

Input types

Required

  • path
    • Specifies the file path to the unstructured file that needs to be read. It is crucial for locating and accessing the file for processing.
    • Comfy dtype: STRING
    • Python dtype: str
  • split_documents
    • A boolean flag indicating whether the input file should be split into multiple documents based on certain criteria. This affects how the data is segmented and structured.
    • Comfy dtype: COMBO[BOOLEAN]
    • Python dtype: bool

Optional

  • extra_info
    • An optional string containing additional information or parameters in JSON format that can be used to customize the reading process.
    • Comfy dtype: STRING
    • Python dtype: str

Output types

  • documents
    • Comfy dtype: DOCUMENT
    • The processed data from the unstructured file, structured as a document or a list of documents, ready for indexing and analysis.
    • Python dtype: tuple

Usage tips

  • Infra type: CPU
  • Common nodes: unknown
