Use Google Sheets AI to Write Usage Statistics Formulas

Tool:Google Sheets

AI Feature:Help me with this formula / Smart fill

Time:10-15 minutes

Difficulty:Beginner

What This Does

Google Sheets' AI assistant lets you describe in plain English what calculation you need — and it writes the formula for you. No formula memorization required for building your monthly library statistics dashboard.

Before You Start

You have a Google account and Google Sheets open (sheets.google.com)
You have your library usage data in a spreadsheet (or you're ready to enter it)
You're logged in to Google

Steps

1. Open your spreadsheet and position your cursor

Open your library statistics spreadsheet in Google Sheets. Click on an empty cell where you want the calculation to appear.

2. Ask for the formula in plain English

There are two ways to use AI in Sheets:

Option A (in-cell): Type = in the cell, then describe what you want in plain English. Sheets may suggest a formula automatically.
Option B (Gemini sidebar): Click the Ask Gemini sparkle icon in the top right corner. Type your request: "Write a formula that adds up column B rows 2 through 50 and shows the total." Gemini responds with the formula to paste.

3. Review and use the result

Copy the suggested formula into your cell. Check that it references the right columns and rows for your spreadsheet. Press Enter to run it.

Real Example

Scenario: You're building your monthly report. You have circulation data in column B (rows 2–100), program attendance in column C, and new library cards in column D. You want a summary row at the bottom and a year-to-date total.

What you type: In the Gemini sidebar: "My spreadsheet has monthly circulation numbers in column B rows 2-13. Write a formula to sum the entire year and calculate the percent change from last year (last year's total is in cell B15)."

What you get: Gemini writes: =SUM(B2:B13) for the annual total, and =(SUM(B2:B13)-B15)/B15 for the percent change — formatted as a percentage.

Tips

If the formula looks right but isn't working, ask Gemini: "This formula returns an error — what's wrong? [paste formula]"
You can also ask Gemini to create a whole dashboard: "Create column headers for a monthly library statistics tracker with: circulation, new cards, program attendance, reference questions, and computer sessions"
For conditional formatting ("highlight cells in red if circulation dropped more than 10%"), describe it to Gemini the same way

Tool interfaces change — if a button has moved, look for similar AI/magic/smart options in the same menu area.
