Course details
In this quick, hands-on course, learn to build a lightweight, AI-powered data analysis tool using Python, Streamlit, and the OpenAI API. Instructor Maggie Ma shows you how to upload a dataset and ask questions in plain English—your app will convert the input into code (Python or SQL), run it, and return useful insights. Perfect for technical teams looking to support non-technical stakeholders, this course takes you through building and testing a natural language interface for structured data. No prior experience with LLMs is needed—just Python and a bit of pandas—and you’ll finish the course with a working prototype you can expand or deploy internally.
Learning objectives
Build a simple Streamlit interface that accepts CSV uploads.
Integrate the OpenAI API to answer data questions in natural language.
Design prompts that turn user input into code for data analysis.
Execute and return summaries or charts based on that generated code.
Test and share your app with stakeholders or teammates.
