Document loaders provide a standard interface for reading data from different sources (such as Slack, Notion, or Google Drive) into LangChain’s Document format. This ensures that data can be handled consistently regardless of the source. All document loaders implement the BaseLoader interface.

​
Interface

Each document loader may define its own parameters, but they share a common API:
  • .load() – Loads all documents at once.
  • .lazy_load() – Streams documents lazily, useful for large datasets.
from langchain_community.document_loaders.csv_loader import CSVLoader

loader = CSVLoader(
    ...  # Integration-specific parameters here
)

# Load all documents
documents = loader.load()

# For large datasets, lazily load documents
for document in loader.lazy_load():
    print(document)
