AI Excel Formula Generator
Tell it what you want to calculate — for example "sum column B where column A is Marketing" — and get a working Excel or Google Sheets formula. The finder below routes common needs (lookups, conditional sums, IF logic, dates) straight to an instant, rule-based builder that writes the formula for you.
Need something more specific? The full Excel AI App turns any plain-English request into a formula with AI on the free plan. The builders here run entirely in your browser — nothing is uploaded and no account is needed.
How to describe a formula so you get the right one
Name the exact ranges (e.g. A2:A100), not just "the column". Specific ranges produce copy-paste-ready formulas.
State every condition explicitly — what to match, whether it's greater/less than, and any date window. Vague requests produce vague formulas.
Say whether you're in Excel or Google Sheets. Most formulas are identical, but a few (like ARRAYFORMULA) differ, and it helps the AI pick the modern function (XLOOKUP over VLOOKUP, IFS over nested IF).
Instant builders vs. AI generation
The builders on this site are deterministic: they assemble a guaranteed-correct formula from your inputs for a specific function (VLOOKUP, XLOOKUP, SUMIF/COUNTIF, IF/IFS, DATEDIF). No guessing, no model — ideal when you already know the function you need.
AI generation, inside the Excel AI App, handles the open-ended cases: you describe an outcome and it chooses the function, writes the formula, and explains it. Always verify an AI-written formula on a small sample before applying it across a sheet.
Frequently asked questions
Is there a free AI Excel formula generator?
Yes. The instant builders on this page are free and run in your browser with no signup. For open-ended, plain-English requests, the Excel AI App generates formulas with AI on its free plan.
Does it work for Google Sheets too?
Yes. The formulas generated use standard functions that work identically in Microsoft Excel and Google Sheets. A handful of Sheets-only functions (like ARRAYFORMULA) are called out where relevant.
Do I have to upload my data?
No. To write a formula, the tool only needs your ranges and the logic — not the underlying rows. The instant builders never send anything to a server.
Which is better — a formula builder or ChatGPT?
For a known function, a builder is faster and can't hallucinate the syntax. For an open-ended "how do I calculate X" question, an AI assistant is better because it picks the function for you. This page gives you both paths.
