streamlit-data-chat

Description

Python Streamlit web application that lets you chat with your data. Upload a CSV or XLSX file and ask questions in natural language; the app uses an LLM-powered agent to answer using your data.

The app uses Streamlit for the UI, pandas for data handling, and LangChain (with the OpenAI API) to run a Pandas DataFrame agent. You load your API key via environment variables, upload a file, and get a data preview plus a chat interface to query it.
