CSV Knowledge Base

Learn how to use local CSV files in your knowledge base.

The CSVKnowledgeBase reads local CSV files, converts them into vector embeddings and loads them to a vector database.

Usage

We are using a local PgVector database for this example. Make sure it’s running

from agno.knowledge.csv import CSVKnowledgeBase
from agno.vectordb.pgvector import PgVector

knowledge_base = CSVKnowledgeBase(
    path="data/csv",
    # Table name: ai.csv_documents
    vector_db=PgVector(
        table_name="csv_documents",
        db_url="postgresql+psycopg://ai:ai@localhost:5532/ai",
    ),
)

Then use the knowledge_base with an Agent:

from agno.agent import Agent
from knowledge_base import knowledge_base

agent = Agent(
    knowledge=knowledge_base,
    search_knowledge=True,
)
agent.knowledge.load(recreate=False)

agent.print_response("Ask me about something from the knowledge base")

CSVKnowledgeBase also supports async loading.

pip install qdrant-client

We are using a local Qdrant database for this example. Make sure it’s running

async_knowledge_base.py

import asyncio
from pathlib import Path

from agno.agent import Agent
from agno.knowledge.csv import CSVKnowledgeBase
from agno.vectordb.qdrant import Qdrant

COLLECTION_NAME = "csv-reader"

vector_db = Qdrant(collection=COLLECTION_NAME, url="http://localhost:6333")


knowledge_base = CSVKnowledgeBase(
    path=Path("data/csv"),
    vector_db=vector_db,
    num_documents=5,  # Number of documents to return on search
)

# Initialize the Agent with the knowledge_base
agent = Agent(
    knowledge=knowledge_base,
    search_knowledge=True,
)

if __name__ == "__main__":
    # Comment out after first run
    asyncio.run(knowledge_base.aload(recreate=False))

    # Create and use the agent
    asyncio.run(agent.aprint_response("What is the csv file about", markdown=True))

Params

Parameter	Type	Default	Description
path	Union[str, Path]	-	Path to the CSV file
reader	CSVReader	CSVReader()	A CSVReader that reads the CSV file and converts it into Documents for the vector database

CSVKnowledgeBase is a subclass of the AgentKnowledge class and has access to the same params.
