Paste your Excel formula.
Get working Sheets syntax.
Teams that work across Excel and Google Sheets spend hours rewriting the same formulas in two different syntaxes. Formula Foundry converts them automatically — including XLOOKUP, SUMIFS, and every named range — and flags anything that can’t be translated so you know exactly where you stand.
- Automatically converts Excel functions to their Google Sheets equivalents
- Flags functions with no direct translation — no surprises mid-migration
- Identifies naming differences between platforms
- Works in both directions: Sheets → Excel too
=XLOOKUP(A2, D:D, E:E)=ARRAYFORMULA(XLOOKUP(...))Just build formulas — no syntax required.
Pick a function, fill in the fields, and watch the formula build itself in real time. The visual builder is designed for marketers, operations managers, and anyone who learned spreadsheets by necessity rather than choice.
- Real-time preview shows your formula before you apply it
- Form-style inputs — no bracket-counting, no comma errors
- Field validation catches mistakes before they reach your spreadsheet
- Supports nested formulas — build complex logic visually, step by step

Change one number.
Update 500 formulas instantly.
You’ve got a discount rate hardcoded in 60 cells across 8 tabs. Finance changes it. You spend 90 minutes tracking them all down — and still miss three. Variables eliminate this. Define @@DiscountRate once, reference it everywhere. Change it in one place and every formula updates automatically.
- Define variables (like
@@TaxRate,@@TargetRevenue) in a dedicated sidebar - Reference them in any formula across any tab — always stays in sync
- Team variables: share variables across your team so everyone uses the same constants
- Scenario analysis: toggle between variable sets to model best/worst case instantly (feature is coming soon)

Type ‘sum column A only if B is Paid’ and get =SUMIF(B:B,"Paid",A:A) with a plain-English explanation. Unlike generic AI tools, Formula Foundry’s AI works inside your editor context — so you can generate a formula, see it explained line by line, and fine-tune it without switching tools.
- Natural language → working formula in seconds
- Explains any formula in plain English — understand it, don’t just copy it
- Debugs errors: paste the error message, get the fix
- Works in context with your open formula — not a separate chatbot
