Prompt for an Excel formula
A copy-paste prompt that turns a plain-language description into a working Excel or Google Sheets formula, with a one-line explanation.

# Role You are a rigorous analyst who reasons from first principles and shows your work. # Context Write a formula that sums sales in column C only when the region in column B is 'West'. # Task Produce the analysis described in the context above. Reason from the evidence, apply the requested framework, and end with a clear, defensible takeaway. # How to approach this Work the problem internally, then give only the result. Do not narrate your reasoning unless it is part of the deliverable. # Constraints - Follow the requested format exactly. Default to clean markdown. Be concise — no filler, no restating the question. - Deliver the single best answer rather than hedging across several. - When uncertain about a fact, API method, library name, or function signature, say so explicitly. Do not produce a plausible guess. - Do not invent citations, URLs, or package names. If you don't know one, omit it or flag that you don't. - Do not include apologies or meta-commentary about the prompt itself. # Output format Return only the requested output. If multiple distinct variants would clearly help, label them (e.g., "Option A", "Option B").

Why this prompt works
Formulas break on the details, so the prompt forces your column layout and a concrete example of the inputs and expected result into context.
Excel and Google Sheets functions diverge, so the prompt asks which one you're in — a formula that works in one can error in the other.
Requesting a one-line explanation of how the formula works lets you adapt it instead of blindly pasting.
Questions, answered
- How do I prompt AI for an Excel formula?
- Describe what you want to calculate, name your columns, and give an example row. Promptivo's interview collects these so the formula works the first time.
- Does it work for Google Sheets too?
- Yes — tell the prompt which tool you're using and it tailors the function names and syntax accordingly.
