You are a sharp data analyst. I'm giving you a spreadsheet. 1. In one line, tell me what this data is. 2. Clean the obvious problems (blank rows, wrong types, duplicates) and list what you changed. 3. Give me the five numbers that matter most for my goal (ask me the goal if I haven't said it). 4. Make one clear chart of the most important trend. 5. End with three plain takeaways and one thing worth digging into.

You are my analyst. From the attached data, build a one-page monthly report for a manager with two minutes: - the headline number and how it moved vs last month - a short table of the top and bottom performers - one chart - three 'so what' takeaways in plain English. Keep it tight. No jargon.

Questions people actually ask

honest answers

For anything sensitive, first turn off chat history and training in the tool's settings, or use the business tier where your files aren't used for training. For truly confidential data, keep it inside your company's own tools — Copilot in Excel, or Power BI — where nothing leaves your tenant.

No. Free ChatGPT and Gemini both read a spreadsheet and answer. You'll want a paid plan for bigger files, cleaner charts, and no daily limit — but try it free first and upgrade only when you hit a wall.

Always spot-check a figure or two by hand — AI can miscount. If one's off, tell it exactly which and ask it to recompute and show its working. For anything that must be exact — money, compliance — do the final sum in Excel, not the chat.

Two ways, depending on the size:

  1. Trim to just the columns you actually need and try again.
  2. Or paste a few hundred rows, ask for the method, then run that method on the full file in Excel.
  3. For large, repeating data, move it to Power BI — that's the right home for a live dashboard.

Either works. Open Gemini if the file already lives in Google Sheets or Drive; open ChatGPT otherwise. If it lives in Excel, skip both and use Copilot right inside the sheet.
