The guide
What is an Excel formula generator?
An Excel formula generator is a tool that writes spreadsheet formulas for you. Instead of remembering the exact syntax of SUMIFS, XLOOKUP or INDEX and MATCH, you describe the result you want in everyday words, such as "add up sales in column D where the region is West and the status is Paid", and the generator returns a formula you can paste straight into a cell.
ExcelFormulaMaker goes further than a plain answer box. Every formula comes with a short explanation, the steps to use it and a worked example on sample rows, so you can check the result before you rely on it.
How the AI Excel formula generator works
This is an AI Excel formula generator: a language model reads your request and builds the formula from the functions your spreadsheet actually supports. Tell it what to calculate, which app you use and, if you like, your header row, and it points the formula at your real columns.
It also respects your Excel version. XLOOKUP, FILTER and TEXTSPLIT work in Microsoft 365 but fail with #NAME? in Excel 2016 or 2019, so for older versions it uses compatible functions instead.
A free Excel formula generator with no sign-up
Unlike tools that want an account or a card first, this free Excel formula generator needs no sign-up: open the page, type your request and copy the result. Data you tidy with the clean my data tool never leaves your device.
An online Excel formula generator that works anywhere
As an online Excel formula generator, there is nothing to install and no add-in to approve with IT. It runs in any modern browser on Windows, Mac, Chromebook, tablet or phone, and the formulas paste into Excel, Excel for the web or Google Sheets.
AI in Excel: when a dedicated generator makes more sense
AI in Excel now means Copilot, which only comes with qualifying Microsoft 365 plans. Many teams still use Excel 2016, 2019 or 2021, or work mainly in Google Sheets. A dedicated generator fills that gap. The formula explainer breaks any formula into plain-English steps, and the formula fixer repairs #N/A, #VALUE! and #REF! errors.
Use it as an equation to Excel formula converter
The generator also doubles as an equation to Excel formula converter. A compound interest equation such as A = P(1 + r/n)^(nt) becomes =B2*(1+C2/D2)^(D2*E2) once you say which columns hold the principal, rate, periods and years. Square roots, powers and π become SQRT, ^ and PI().
An Excel formula list for everyday tasks
The Excel formula list in our library is checked by hand, with Excel and Google Sheets versions, covering:
- Lookups with XLOOKUP, VLOOKUP and INDEX and MATCH
- Conditional totals and counts with SUMIFS and COUNTIFS
- Text tasks such as extracting a first name or removing extra spaces
- Date maths such as working days between two dates
- Duplicates, unique values and finance formulas
For unfamiliar error codes, the Excel error guide explains what each one means and how to fix it.
