How it works

Example prompts and the formulas you get

Eight common asks and the real Excel formulas that answer them. Swap the cell references for your own ranges.

Want this inside Excel?

This free page hands you a formula to copy. HISAB 360 goes further: the Excel add-in writes formulas directly into your sheet, aware of your headers and ranges, so there's nothing to paste or re-reference. Ask in plain English and the answer lands in the cell you're standing on — then keep going with offline Python automation for the heavy lifting, ERP connectors that pull live data in, and VBA generation that turns repeated work into one-click commands.

Because HISAB lets you bring your own AI — plug in your existing Claude or ChatGPT subscription or API key — there's no per-generation markup or hidden cost on top of what you already pay the AI provider. See the full feature set, run real Python in Excel locally, or follow the step-by-step tutorials. Need a whole macro instead of a single formula? Try the VBA macro generator.

Frequently asked questions

Is the Excel formula generator free?

Yes. Generating formulas on this page is completely free. There's a small daily limit to keep the service available for everyone, but there is no charge and no card required.

Do I need to sign up or log in?

No. You can type a request and get a formula without creating an account or logging in. Signup is only needed if you want the full HISAB 360 add-in inside Excel.

Which Excel versions do the formulas work in?

Core functions like SUMIFS, VLOOKUP, IFERROR, DATEDIF and RANK.EQ work in Excel 2016 and later, and in Google Sheets. Newer functions such as XLOOKUP, UNIQUE, TEXTBEFORE and TEXTAFTER need Microsoft 365 or Excel 2021+ — the tool will note when that applies.

Is my data stored?

No spreadsheet data is involved — you only type a plain-English description of the formula you need, and we don't store your prompts to build a profile. Nothing from your workbook is uploaded here.

What is the daily limit?

The free generator allows a handful of formula generations per day per visitor. If you hit the limit you'll see a message and can come back tomorrow — or install HISAB 360 and use your own AI key for unlimited formulas written straight into your sheet.

Formulas written into your sheet, not just copied
