You know the feeling. You need a VLOOKUP but can't remember the syntax. You Google it. You read three Stack Overflow answers. You try it. It breaks. You Google the error. 20 minutes gone.

AI formula generators fix this. You describe what you need in plain English, and you get the exact formula in 3 seconds. Here's how.

Step 4: Copy and Paste

SheetSmart generates the formula and explains how it works. Click Copy, click into your target cell, paste. Done.

What Formulas Can AI Generate?

Essentially anything. The AI understands all Google Sheets functions including newer ones like XLOOKUP, FILTER, UNIQUE, LAMBDA, LET, and MAP. Some examples:

The Explain Feature

Got a formula you don't understand? Paste it into the Explain tab. SheetSmart breaks it down in plain English — what each function does, how they're nested, and tips for common mistakes.

This is perfect for inheriting someone else's spreadsheet or learning from the formulas AI generates for you.

Is It Free?

Yes. You get 10 free formula generations per day. For most people, that's plenty. If you need unlimited, Pro is $7.99/mo or $59.99/yr.
