langchain_community.document_loaders.csv_loader.UnstructuredCSVLoader¶

class langchain_community.document_loaders.csv_loader.UnstructuredCSVLoader(file_path: str, mode: str = 'single', **unstructured_kwargs: Any)[source]¶

Load CSV files using Unstructured.

Like other Unstructured loaders, UnstructuredCSVLoader can be used in both “single” and “elements” mode. If you use the loader in “elements” mode, the CSV file will be a single Unstructured Table element. If you use the loader in “elements” mode, an HTML representation of the table will be available in the “text_as_html” key in the document metadata.

Examples

from langchain_community.document_loaders.csv_loader import UnstructuredCSVLoader

loader = UnstructuredCSVLoader(“stanley-cups.csv”, mode=”elements”) docs = loader.load()

Parameters

  • file_path (str) – The path to the CSV file.

  • mode (str) – The mode to use when loading the CSV file. Optional. Defaults to “single”.

  • **unstructured_kwargs (Any) – Keyword arguments to pass to unstructured.
