Free AI Excel · No sign-up · 20 generations a day
AI Excel — write, fix and explain any Excel formula in seconds
AI Excel turns plain English into a working formula for Excel or Google Sheets, with a line-by-line explanation of what it does. No account, no credit card, no download.
This AI Excel assistant works with Excel 2016 through Microsoft 365, and with Google Sheets.
Why people go looking for AI Excel help
You know the answer, not the syntax
You can describe exactly what the column should do. Turning that into nested IFs and an INDEX/MATCH is the part that eats the afternoon, and it is the part an AI Excel tool removes.
Someone else's formula breaks
You inherit a sheet, a cell shows #REF!, and the formula is four hundred characters with no line breaks. Understanding it comes before fixing it, which is where an AI Excel explainer earns its place.
Every tool wants an account first
Most AI Excel tools put a sign-up, a card, or a ten-message trial between you and the one formula you needed a minute ago. This one does not.
What this free AI Excel assistant does
Plain English to formula
Describe the result. The AI Excel formula generator writes it for Excel or Google Sheets, with the dialect differences handled for you.
Explain anything
Paste a formula you did not write. Get it reformatted with the nesting visible, evaluated from the inside out.
VBA and macros
Describe the automation. Get a complete Sub with Option Explicit and every object reference qualified.
Regex that actually runs
Patterns targeted at RE2, the engine behind Excel's REGEXEXTRACT and Google Sheets' REGEXMATCH — so no lookbehind surprises.
336 function references
Every function gets a page with real syntax, worked examples, its actual error modes, and an AI Excel generator scoped to that function.
Nothing stored
No account means no history, no profile, and nothing about your data to leak. The formula is generated and forgotten.
Browse by category
Every function, grouped the way Excel groups them. Each page carries the real signature, three worked examples on one dataset, the error codes that function actually produces, and an AI Excel formula generator scoped to it.

What an AI Excel tool does
AI Excel describes a class of tool that turns a sentence into a spreadsheet formula. You write what the cell should contain; the tool writes the syntax. That is the whole promise, and for the narrow job of getting an unfamiliar formula right it holds up well.
What separates a useful AI Excel assistant from a frustrating one is rarely the underlying model — most of them call the same frontier models. It is whether the tool tells you which Excel version the answer needs, and whether it names the things that will break the formula before you paste it into a live sheet.
It cannot see your spreadsheet, and that is the trade
A browser-based AI Excel generator receives one thing: your text. It does not know your column headers, where your data starts, or that column D holds text that looks like numbers. Anything it needs has to be in the sentence.
That limitation is also why there is no upload, no account and nothing stored. Name your columns in the description and this AI Excel tool produces a formula you can paste directly; leave them out and you get generic column letters you then have to remap.
Excel and Google Sheets are not the same language
Every tool here has a dialect switch, because the gaps between the two matter. XLOOKUP, LET and the dynamic array family need Microsoft 365 and simply do not exist in Excel 2019. QUERY has no Excel equivalent at all.
Set the dialect before you generate rather than translating afterwards — the difference is structural, not cosmetic, and a good AI Excel assistant should flag the version requirement rather than let you discover it when a colleague opens the file.
Always check the formula
AI Excel output fails in one specific way: a plausible formula with one wrong argument. It returns a number, there is no error, and the number is wrong. No tool in this category is exempt, including this one.
Three habits catch nearly all of it. Test against one row where you already know the answer. Check what happens on a blank cell. Confirm the range covers the rows you will add next month, not only the rows there today.
Free, with no account
Every AI Excel tool on this site runs without a sign-up. The limit is 20 generations per day per visitor, which resets daily, and there is no paid tier to upgrade to — the cap exists because the AI costs real money per call, not to push you toward a subscription.
If you already know which function you need, the reference library covers 336 of them with syntax, worked examples and error tables. If you do not, describe the result and let the AI Excel formula generator pick the function for you.
Frequently asked questions
- Is this really free?
- Yes. There is no account, no card, and no trial that expires. Every visitor gets 20 AI Excel generations a day per IP address, which resets at midnight UTC. The limit exists because the AI costs us money per call, not to push you toward a paid tier — there isn't one.
- Do I need to sign up?
- No. There is no sign-up on this site at all. Type your request into the box and press Generate — that is the entire AI Excel workflow here.
- Does it work with Google Sheets?
- Yes. Every tool has an Excel / Google Sheets switch, and the answer changes accordingly — ARRAYFORMULA and QUERY where those are the idiomatic Sheets answer, and the right argument separator for each.
- Which Excel versions are supported?
- The AI Excel generator targets Excel 2016 and later and tells you when a formula needs Microsoft 365 or 2021 for functions like XLOOKUP, LET or the dynamic array family. Each function reference page also states its availability.
- Is my data sent anywhere?
- Your prompt is sent to Cloudflare Workers AI to be answered, and that is the whole journey. We store no account, no history, and no copy of what you typed. Do not paste anything confidential into any AI tool, including this one.
- Can I use the formulas commercially?
- Yes. A formula is not something we claim rights over. Use what you get in whatever work you like.
- What if the formula is wrong?
- Check it. Language models get spreadsheet syntax right most of the time and confidently wrong some of the time, which is why every AI Excel answer ships with a 'Watch out for' section and why the function reference pages document each function's real error modes. Treat the output as a strong first draft, not as a guarantee.
