To do data analysis with AI, upload your data to ChatGPT or Claude, ask clear questions, and verify the results. AI can summarise, chart and find patterns — but check its numbers and method.

Upload and ask

Upload a spreadsheet or CSV to ChatGPT or Claude and ask specific questions: ‘summarise sales by month’, ‘find the top 10 customers’, ‘plot this trend’. They can clean data, calculate, and generate charts. Be precise about what you want.

Go deeper

Ask the AI to explain its method, check for outliers, or compare segments. For spreadsheet-native analysis, use Copilot in Excel or Gemini in Sheets. For repeatable analysis, ask the AI to write the formula or code so you can re-run it.

Verify the analysis

AI can make analytical errors and present wrong figures confidently. AI can fabricate facts, figures and citations with total confidence (a “hallucination”). Treat AI output as a draft and verify anything important against a reliable source — this matters most for medical, legal, financial and academic use. Sanity-check totals, spot-check a few rows, and confirm the method makes sense. Don’t upload sensitive or regulated data without checking the tool’s data-handling terms.

If you find yourself juggling a separate subscription for chat, automation, transcription and image generation, one option worth knowing is a single platform that runs them together — osFoundry is one such agentic AI platform that consolidates chat, agents and internal apps in one workspace, with a bring-your-own-key model so you choose the underlying AI.
