# Excel-Aware RAG Chatbot

This Streamlit app lets you upload an Excel file (with a 'Data Base' sheet), processes the data into a retrievable vector database, and allows question answering using a RAG pipeline powered by `flan-t5-base`.

## Features
- Upload `.xlsm` or `.xlsx` files
- Automatically cleans and processes the 'Data Base' sheet
- Embeds entries using `MiniLM` embeddings
- Uses `flan-t5-base` for fast CPU-friendly QA
- Works on Hugging Face Spaces (L4 hardware)

## Run Locally

```bash
pip install -r requirements.txt
streamlit run app.py
