Which business analyses are good spreadsheet candidates?
Spreadsheets are strongest when the work has explicit variables, repeatable calculations, and a decision that benefits from comparison. Revenue scenarios, budgets, pricing, capacity planning, campaign economics, inventory views, hiring plans, and market-sizing models all fit when their assumptions can be stated clearly.
Use a document or database instead when the core problem is narrative, unstructured evidence, high-volume records, or multi-user operational transactions. The spreadsheet can still summarize the result, but it should not become a fragile substitute for every system.
Scenario model
Shows how a small set of drivers changes revenue, cost, cash, capacity, or another outcome over time.
Decision calculator
Compares options through a transparent formula, sensitivity table, and documented decision threshold.
Operating tracker
Captures a repeatable set of metrics with definitions, owners, dates, and exception flags.
Research model
Combines sourced inputs with formulas for market size, pricing, competitive comparisons, or prioritization.
Use a four-layer model architecture
A well-structured workbook reduces accidental edits and makes review faster. The exact tab names can vary, but inputs, calculations, checks, and outputs should be separable. Color alone is not enough; use labels, notes, named ranges where appropriate, and a short instructions area.
Inputs
Editable assumptions, source, owner, date, units, and scenario selection live in a controlled area.
Calculations
Formulas transform inputs without hidden hard-coded values or unexplained manual overrides.
Checks
Reconciliations, balance tests, missing-input warnings, and range checks surface errors early.
Outputs
Decision-ready summaries, scenarios, charts, and recommended actions use consistent definitions.
What to inspect in AI-generated formulas
A formula can be syntactically valid and still be wrong. Check period alignment, units, signs, denominators, absolute versus relative references, blank handling, error handling, and whether the formula responds to the intended scenario switch. Recalculate a small sample independently.
Watch for hard-coded values inside formulas. If a number represents an assumption, place it in the input layer and reference it. If it represents a fixed rule, document the rule. This makes future updates safer and helps reviewers distinguish business judgment from spreadsheet logic.
- Every important input has a label, unit, date, source, and owner.
- No material assumption is hidden inside a calculation formula.
- Monthly, quarterly, and annual periods reconcile correctly.
- Percentages use the intended denominator and signs are consistent.
- Scenario switches update every dependent output.
- Totals and subtotals reconcile to the detailed schedules.
- Charts reference the correct range and show units and time periods.
- A reviewer can reproduce at least three key outputs independently.
Add a decision layer instead of stopping at the model
The workbook should explain what the numbers mean. Create a concise output sheet with the decision, current scenario, key assumptions, headline outputs, sensitivities, threshold alerts, and recommended next actions. This is where analysis becomes useful to an operator.
Do not overstate precision. Use ranges and confidence labels when inputs are uncertain, and show which assumption drives the most variance. A sensitivity table is often more informative than a single “best estimate.”
Generated table vs decision-ready workbook
A workbook is valuable when it remains understandable and adaptable after the generation session ends.
| Model quality | Generated table | Decision-ready workbook |
|---|---|---|
| Assumptions | Mixed into cells and formulas | Centralized, labeled, sourced, dated, and editable |
| Calculations | Plausible outputs with limited traceability | Readable formulas, controlled dependencies, and checks |
| Uncertainty | One forecast or answer | Scenarios, sensitivities, confidence, and thresholds |
| Handoff | Requires the creator to explain it | Includes instructions, definitions, source notes, and a decision summary |
Build an auditable spreadsheet with AI
Use the steps below for forecasts, budgets, pricing models, market sizing, unit economics, and other business analyses.
- 01
Define the decision and model boundary
Outcome: A model specification with question, audience, period, units, and excluded complexity.
- Write the decision the workbook must support.
- List the inputs the user can supply and the outputs the model must calculate.
- 02
Create the assumption register
Outcome: A source-aware input layer with owners, dates, units, and confidence.
- Separate observed values from estimates and policy choices.
- Identify which assumptions need scenarios or sensitivity ranges.
- 03
Generate structure and formulas
Outcome: A workbook with input, calculation, check, and output layers.
- Require plain-language notes for key formulas.
- Keep material assumptions out of formula strings.
- 04
Test and reconcile
Outcome: Evidence that formulas respond correctly and totals agree.
- Use simple test values and independent sample calculations.
- Inspect edge cases, blanks, zero values, negatives, and scenario changes.
- 05
Build the decision summary and export
Outcome: A reviewer-ready workbook with headline findings and next actions.
- Show the current scenario, key drivers, sensitivities, and thresholds.
- Open the exported file and verify formulas, formatting, charts, and notes.
Prompts you can use
Replace the bracketed details, attach the relevant source material, and keep the review step in the same workspace.
Scenario workbook
Prompt 01Create an editable spreadsheet model for [decision]. Separate Inputs, Calculations, Checks, and Summary. Add source, date, unit, owner, and confidence fields for important assumptions. Include base, downside, and upside scenarios plus a sensitivity table for the two highest-impact drivers.
Why it works: It specifies model architecture, audit fields, uncertainty, and the decision layer.
Formula audit
Prompt 02Audit this workbook for hard-coded assumptions, broken references, period mismatches, unit errors, incorrect denominators, unreconciled totals, and charts using the wrong range. Repair issues and add a Checks sheet that exposes future failures.
Why it works: It names common spreadsheet failure modes and asks for persistent controls.
Executive summary
Prompt 03Create a one-page Summary sheet for [audience]. Show the decision, selected scenario, five key assumptions, headline outputs, the most sensitive driver, threshold alerts, limitations, and recommended next actions. Link every figure to the model rather than copying values.
Why it works: It connects the underlying analysis to a usable management view without duplicating data.

How this guide was prepared
The Kona Team prepared this guide from financial-model and spreadsheet-generation controls used in business workflows: explicit assumptions, traceable formulas, scenario logic, reconciliation, decision summaries, and exported-file verification. Users should independently review models used for financial or other consequential decisions.
