Turn a messy spreadsheet into answers you can trust. Using free AI tools — no coding, no installation — you'll build a conversational data analyst for a small UK coffee chain, run five real business questions, and verify the answers by hand. Inspired by the open-source PandasAI library. You finish with portfolio evidence: your analyst prompt, five answers, one verified result, one AI mistake you caught, and one improvement you made.

Begin your data analysis journey with three guided projects across Retail, Health and Finance. Learn how to understand unfamiliar datasets, spot data-quality issues, check AI-generated summaries and verify key figures using Excel or Google Sheets. No previous experience is required.
