TL;DR - Upload a spreadsheet and ask questions in plain English. AI data tools find trends, clean data, and make charts - no formulas required. Just verify the numbers.
Why it matters
Data analysis used to need SQL or Excel skills. Now anyone can ask "what does this tell me?" and get an answer - a genuine superpower for non-analysts.
Worked example
[Upload sales.csv] Columns: Date, Region, Product, Revenue.
- Summarize the top 3 trends.
- Flag any month that dropped more than 20%.
- Make a chart of monthly revenue and recommend one action.
- If anything's ambiguous, ask me before assuming.Steal this - data asks
Clean: "Remove duplicates and standardize the date column."
Explore: "What are the 3 biggest patterns? Any anomalies?"
Decide: "Given this, what one action would you recommend, and why?"
Always: "Show how you calculated key numbers."Common mistakes (and the fix)
- Trusting the number blindly. Fix: ask how it was calculated; spot-check one.
- Letting it misread columns. Fix: describe the columns up front.
- Pasting sensitive data into a public tool. Fix: anonymize or use a private/enterprise tool.
Good to know
ChatGPT's data analysis (it writes and runs real Python on your file - actual computation, not guessing) and Gemini in Google Sheets are the go-tos. Because they compute rather than predict, their math is trustworthy - but still verify the setup and conclusions.
