02
Build a sheet from one prompt
Build a content calendar for the next eight weeks with columns for date, platform, topic, format, status, and link, plus a status dropdown.
03
Write formulas
Describe what you need in plain words
Request QUERY, FILTER, ARRAYFORMULA, or XLOOKUP where they help
Have Gemini explain each part
Write a formula that counts, for each person in column B, how many of their tasks in column C are marked Done.
04
Fill cells with AI
Sort feedback into positive, neutral, or negative
Turn feature lists into short product descriptions
Pull company names out of email addresses
Summarize long text cells
Spot-check the results. AI can misread unusual entries, and the AI function has usage limits.

Standardize names, dates, and number formats
Remove duplicates
Fix inconsistent categories
06
Analyze and chart
Ask Gemini to surface trends and outliers
Build pivot tables from a plain-language request

Summarize the results in a few sentences
07
Automate with Apps Script

Examples: email someone when a status changes, or tidy up new rows
Test it on a copy first
Read the code before you authorize it
08
Check the AI’s work
Recalculate the key totals
Review a sample of AI-filled cells
Undo mistakes with version history
09
Protect your data
Follow the AI rules your organization sets
Share sheets that hold personal data no more widely than needed
Review sharing settings before you use AI features

Try these prompts
“Summarize this sheet in three bullets.”
“Turn overdue tasks red.”
“Build a pivot table of spend by category and month.”
“Recommend charts for a weekly dashboard.”
The golden rule
Never let AI fill a sheet you do not check. Use it for speed, then verify the numbers that matter.
