Best AI for spreadsheets: formulas first, narration second
Spreadsheet AI is useful when it shows the formula, respects cell references, and fails visibly on missing data — not when it prettifies a guess.
What actually matters
- Require visible formulas, cell references, and intermediate checks.
- Test joins across sheets, date boundaries, currency units, and blank cells deliberately.
- Keep sensitive exports out of prompts unless the whole pipeline is approved for it.
- Measure rework time when the model changes structure you did not ask for.
The shortlist
- A reasoning model for ambiguous analysis with an analyst in the loop.
- A budget model for extraction, classification, and templated transformations.
- Native spreadsheet copilots when audit trails and permissions already live in the suite.
Evidence-backed entries
A sensible test workflow
- 01Start from a known workbook with golden totals and one deliberate edge case.
- 02Ask for a plan and validation checks before accepting structural edits.
- 03Compare outputs against pivot tables or SQL you already trust.
Common mistakes
- Accepting a polished summary without inspecting the formulas behind it.
- Letting the model rename columns or merge sheets without approval.
- Pasting confidential exports into a consumer account with unclear retention.
