DataChat: Conversational Data Analysis with Ollama

DataChat is an interactive web application that lets you analyze and explore your datasets using natural language. Simply upload your CSV or Excel file, and start asking questions about your data in plain English. DataChat leverages the power of Ollama (gemma:2b) for language understanding and LangChain for seamless integration with data analysis tools.

Features

• Intuitive Chat Interface: Ask questions about your data in a conversational manner.
• Support for CSV and Excel Files: Easily upload your data from common file formats.
• Powerful Data Analysis: Get answers to questions about trends, statistics, distributions, and relationships within your data.
• Seamless Integration: Leverages LangChain to connect Ollama with data analysis tools like Pandas.

Getting Started

1. Prerequisites:

   • Python 3.12
   • Ollama installed and running (see: https://ollama.ai/)

2. Installation:

   git clone [https://github.com/WizKnight/DataChat]
   cd DataChat
