A Langchain app that allows you to ask questions to a CSV file

Langchain Chat-CSV with OpenAI (Tutorial)

You can find the step-by-step video tutorial to build this application on YouTube.

This is a Python application that enables you to load a CSV file and ask questions about its contents using natural language. The application leverages Language Models (LLMs) to generate responses based on the CSV data. The LLM will only provide answers related to the information present in the CSV.

How it works

The application reads the CSV file and processes the data. It utilizes OpenAI LLMs alongside with Langchain Agents in order to answer your questions. The CSV agent then uses tools to find solutions to your questions and generates an appropriate response with the help of a LLM.

The application employs Streamlit to create the graphical user interface (GUI) and utilizes Langchain to interact with the LLM.
