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 1: Install SheetSmart (Free)
SheetSmart is a Chrome extension that adds an AI formula assistant directly inside Google Sheets. No account creation, no API key, no setup.
Install SheetSmart from the Chrome Web Store
Step 2: Open Any Google Sheet
Once installed, click the SheetSmart icon in your Chrome toolbar. A side panel opens right next to your spreadsheet.
Step 3: Describe What You Need
Type your request in plain English. For example:
- "Sum column B where column A says Revenue"
- "Find duplicates in column C"
- "VLOOKUP product name from Sheet2 using ID in A2"
- "Average salary where department is Engineering"
- "Count cells that contain the word pending"
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:
- Lookups: VLOOKUP, HLOOKUP, XLOOKUP, INDEX/MATCH
- Conditionals: SUMIF, COUNTIF, AVERAGEIF, IFS
- Arrays: ARRAYFORMULA, FILTER, SORT, UNIQUE
- Text: CONCATENATE, SPLIT, REGEXMATCH, SUBSTITUTE
- Dates: DATE, YEAR, MONTH, NETWORKDAYS, DATEDIF
- Advanced: QUERY, IMPORTRANGE, LAMBDA, nested formulas
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.
