Direct answer
AI can help with Excel and CSV analysis, but only when you design the workflow for verification.
If you need the full protocol, read: Using AI to analyze Excel/CSV correctly.
Why spreadsheet questions break models
Spreadsheet analysis combines:
- numeric computation
- implicit assumptions
- edge cases
Without structure, models will fill gaps with plausible text.
A workflow that produces correct answers
- Define your question precisely.
- Provide the table schema and sample rows.
- Force intermediate computations.
- Validate totals and edge cases.
- Summarize conclusions with traceability.
Prompt templates
Template: sanity-checked summary
Ask for:
- computed totals
- key anomalies
- list of assumptions
- what would change the conclusion
Template: verification
Ask the model to:
- find contradictions
- spot-check calculations
- flag unsupported claims

Tools and measurement
If you care about correctness, run repeated tests.

Operator checklist
- Re-run the same task 5–10 times before drawing conclusions.
- Change one variable at a time (prompt, model, tool, or retrieval).
- Record failures explicitly; they are the fastest route to signal.
