01

Your AI options in Sheets

Gemini in Sheets
Builds sheets, answers questions, analyses data, and writes formulas
Fill with Gemini
Generates, categorizes, or summarizes text across many cells
The AI function
A cell function that uses AI on your data
Other assistants
ChatGPT, Claude, or Gemini chat for formulas and analysis

Gemini in Sheets is included on Google Workspace Business Standard and higher, and on some Google AI consumer plans. Limits and features vary by plan.

Let AI do the repetitive cells. You design the sheet.

02

Build a sheet from a prompt

Create a content calendar for the next eight weeks with columns for date, platform, topic, format, status, and link, with a dropdown for status.

03

Write formulas

  • Describe what you want in plain words
  • Ask for QUERY, FILTER, ARRAYFORMULA, or XLOOKUP when useful
  • Ask Gemini to explain each part

Write a formula that counts how many tasks in column C are marked Done for each person in column B.

04

Fill cells with AI

  • Categorize feedback as positive, neutral, or negative
  • Write short product descriptions from features
  • Extract company names from email addresses
  • Summarize long text cells

Spot-check results. AI can misread unusual entries, and the AI function has usage limits.

05

Clean data

  • Split and combine columns
  • Standardize names, dates, and formats
  • Remove duplicates
  • Fix inconsistent categories
06

Analyse and chart

  • Ask Gemini for trends and outliers
  • Create pivot tables from a plain request
  • Ask for the best chart for your question
  • Summarize results in a few sentences
07

Automate with Apps Script

  • Ask AI to write Apps Script for repeated tasks
  • Examples: send an email when a status changes, or tidy new rows
  • Test on a copy first
  • Read the code before authorizing it
08

Check AI’s work

  • Recalculate key totals
  • Check a sample of AI-filled cells
  • Use version history to undo mistakes
09

Protect your data

  • Follow your organization’s AI rules
  • Do not share sheets with personal data more widely than needed
  • Check sharing settings before using AI features
10

Prompts to try

  • “Summarize this sheet in three bullet points.”
  • “Highlight overdue tasks in red.”
  • “Create a pivot table of spend by category and month.”
  • “Suggest charts for a weekly dashboard.”

The golden rule

Do not let AI fill a sheet you never check. Use it for speed, then verify the numbers that matter.

Ask Gemini to build one tracker you need this week, then customise it yourself.
