Excel Formula Generator
Excel Formula Generator that actually remembers your work.
Describe what you need in plain English and get a working Excel formula — then save it as a reusable snippet and refine it in a real multi-line editor. It's a formula workspace, not a one-shot box you paste into and forget.

Free, runs in your browser — no signup. Inserting into your real sheet, AI, and sync go live the moment you add it to Excel.
How the Excel formula generator works
Describe it, get the formula, keep it.
Describe the result in plain English
Type what the cell should show, the way you would ask a colleague: "total sales for the West region in March" or "flag invoices that are overdue and unpaid". Mention the columns or table names you are working with and the generator uses them.
Review it in the multi-line editor
The formula lands in a real editor, not a text box. Functions, ranges and operators are color-coded and nested functions are indented on their own lines, so you can check the logic before trusting it and change any part by hand.
Save it as a snippet, insert it into the sheet
Insert the formula into the selected cell with one click. Save the ones you will need again as snippets, so next month's version of the same report starts from a tested formula instead of a fresh prompt.
More than an Excel formula maker
Your spreadsheet experience, reimagined.
Excel formula generator examples
Five prompts and the formulas they return.
You type
Sum of column C where the region in A is West and the month in B is March
Formula
=SUMIFS(C:C, A:A, "West", B:B, "March")SUMIFS takes the range to add first, then range and criteria pairs. Works in every Excel version and unchanged in Google Sheets.
You type
Look up the price for the SKU in E2 from the Products table, blank if the SKU is missing
Formula
=XLOOKUP(E2, Products[SKU], Products[Price], "")The fourth argument returns a blank only when the SKU is not found, so other errors still show. XLOOKUP needs Excel 2021 or Microsoft 365.
You type
Split the full name in A2 into first and last name
Formula
=TEXTSPLIT(A2, " ")The result spills into the cells to the right. A middle name gets its own column. TEXTSPLIT is Microsoft 365 and Excel for the web only.
You type
Flag rows where the due date in D is in the past and the status in F is not Paid
Formula
=IF(AND(D2<TODAY(), F2<>"Paid"), "Overdue", "")Both conditions sit inside AND, so a paid invoice is never flagged. Fill it down the column. Works in any Excel version.
You type
Average of the last 12 values in column B, ignoring empty cells
Formula
=AVERAGE(TAKE(FILTER(B:B, B:B<>""), -12))FILTER drops the blanks and TAKE with -12 keeps the last twelve entries, so the average moves as rows are added. Needs Microsoft 365.
Excel formula builder, maker & writer
Same job, four names.
People search for an Excel formula builder, an Excel formula maker, a formula writer or a formula helper. The task behind each name is the same: turn a sentence about your data into a formula that works in the cell.
Formula Foundry covers both senses of "builder". The AI writes the formula from your description, and the visual builder lets you assemble one by filling in form fields for each argument, with a live preview of the formula as you go. Either way the result opens in the same editor, where you can read and change it.
What most generators skip is the part after the answer. Every formula you keep becomes a reusable snippet, so the tool gets more useful the longer you use it instead of starting from a blank prompt every time.
Formula Foundry reviews
What our users say
Formula Foundry is genuinely impressive. Simplifying complex formulas, adding variables, snippets, and multi-tab editing inside Sheets is such a game-changer. As someone who has to deal with sheets, dashboards and pipelines every day, this feels like a tool built exactly for the pain points data people deal with.

Variables and vlookup are extremely useful in transferring Excel skills and keeping a sheet clean, as well as processing in fewer steps than I otherwise would have known how.
Jason Tau
Senior Financial Planning Analyst
I found the AI Assistant extremely helpful because it saved me time by generating formulas automatically and suggested improvements I might not have thought of. It made complex tasks much easier and more intuitive, especially for repetitive or complicated formulas.
Anand Kumar Gade
Financial & Reporting Analyst
As a marketer, I always end up back in spreadsheets — forecasting, funnel math, quick models, etc. I'm thrilled Formula Foundry created a productivity tool that actually makes a difference with my critical spreadsheet work.

Vice President Marketing
My favorite feature is the editor and being able to more easily structure my formulas. The easy readability is a game changer! Also, the variables are super useful when I need to put together a complex report.

Excel formula generator FAQ
Excel Formula Generator FAQ
- Describe the result you want in plain English and the generator writes the Excel formula for you. You can then tweak it in the editor, ask for an explanation, or save it as a snippet to reuse later — so you're building a library, not regenerating from scratch every time.
- Yes. There's a free plan with no credit card required, and a free in-browser playground you can try without installing anything. Paid plans unlock higher AI limits and team snippet sharing.
- Yes — it installs as an Excel add-in from the Microsoft Marketplace and runs in the side panel next to your sheet. The same workspace also runs in Google Sheets, so a formula you build in one carries over to the other.
- No. Generating formulas from English is one feature. The point is the workspace around it: a multi-line editor, a visual builder, reusable variables, and a snippet library you and your team build up over time.
- The editor runs in your Excel or Google Sheets, and formulas are computed there, not on our servers. The AI assistant is opt-in and only sees the formula you ask about, your sheet headers and your @@variables. We only store your account details and the snippets you choose to save, and you can delete them anytime.
- Yes. Paste the formula into the editor and pick Explain Formula or Fix Error in the AI assistant. You get a plain-English walk-through of each part, or the most likely cause of the error and a corrected version you can edit before inserting it.
