Quick answer: ChatGPT can write and explain Excel formulas, suggest ways to clean data, help you plan charts and outline slide decks with speaker notes. Check every result against your data, and avoid uploading confidential spreadsheets to tools you have not approved.
Spreadsheet Help You Can Ask For
1. Write a formula in plain English
“In Excel, column B has dates and column C has sales. Write a formula that totals sales for March 2026.” Tell it which spreadsheet app you use, since functions differ.
2. Explain a formula you inherited
Paste the formula and ask: “Explain this step by step as if I’m new to Excel, and point out anything that could break.”
3. Fix an error
Share the error message (such as #VALUE! or #N/A) with a short description of your data layout, and ask for likely causes.
4. Clean messy data
Ask for steps to split full names, remove extra spaces, standardize dates or find duplicates. Work on a copy of your file.
5. Plan pivot tables and charts
“I have sales by product, region and month. Suggest three pivot tables that would answer: which region is growing fastest, which product is slowing and which month is strongest. Describe the fields to use.”
6. Learn functions faster
Ask for a simple example of lookup, conditional and text functions, each with a small sample table.
Presentations: Outline First
- Define the audience and goal: “Persuade the team to approve a pilot.”
- Get an outline: a title for each slide with one key point.
- Draft slide text: short bullets, not paragraphs.
- Add speaker notes: what to say, in a natural spoken style.
- Suggest visuals: chart types or simple diagrams for each key slide.
- Practice: ask for likely questions and answers.
Accuracy Checklist
- Test formulas on a few rows where you know the right answer.
- Check totals against the source.
- Never trust numbers the AI calculated mentally. Use spreadsheet calculations.
- Verify statistics and sources you add to slides.
Privacy First
Spreadsheets often contain customer, staff or financial data. Remove or anonymize sensitive information before sharing it with any AI tool, and follow your organization’s rules. Our data privacy and AI guide explains why.
