AI Spreadsheet Generator: Design a Workbook from a Brief

Worked example

Specify an event budget that can grow

Illustrative example written for this guide. Model outputs vary.

The specification separates inputs from calculations. It does not invent supplier prices or treat an illustrative budget as a quotation.

Prompt to adapt

Design an event-budget workbook with Items, Summary and Assumptions sheets. Use one row per item, with category, description, quantity, unit price and total. Mark example data clearly. Explain the total formula and provide checks for missing prices and negative quantities.

Define what one row represents

Choose a consistent unit: one expense, one booking or one inventory item. Mixing a category subtotal with individual items in the same data range can double-count the total.

List the fields needed to answer your question. Give dates, identifiers and numeric values their own columns. Specify the currency and whether a blank means unknown, not applicable or intentionally empty.

Describe calculations and views separately

Explain each calculation in plain language before asking for a formula. For an expense, total equals quantity multiplied by unit price. For a project, a deadline is not the same field as its completion date.

Keep the source table separate from summary views. Ask for readable labels, filters and frozen headers where useful, while prioritizing a structure that can accept new rows.

Test the generated workbook

Try one ordinary row, an incomplete row and an edge case such as a zero quantity. Check formulas, summaries and references after adding a row. Replace illustrative data with your own inputs before using the result.
