Quick Answer
Google Sheets in 2026 is catching up fast to Excel's Copilot with Help me organize (Gemini-generated tables), the Gemini side panel (chat about your data), Smart Fill (pattern-based auto-complete), formula suggestions, and Connected Sheets (BigQuery at scale).
Most features require a Google Workspace Business Standard+ plan or Google One AI Premium ($19.99/month personal).
What Is Gemini in Google Sheets?
Gemini in Google Sheets is the AI layer built into Sheets, replacing the older "Explore" sidebar with a full conversational Gemini. You can ask questions about your data, generate tables from prompts, write formulas in natural language, and get automatic insights — all without leaving the spreadsheet.
Why Data Workers Use Sheets AI in 2026
- 3+ billion Google Workspace users worldwide
- Google Sheets has 1.8 billion active users (Google I/O 2026)
- 54% of Workspace customers now use Gemini weekly
- Help me organize is used 12 million times/month
- Connected Sheets handles 100 billion+ rows via BigQuery
Top Use Cases / Workflows
1. Generate a table from a prompt. In a new sheet, click the Gemini sparkle → "Help me organize" → "Make a project tracker with task, owner, status, due date, priority." Gemini creates the headers and sample rows.
2. Ask questions about your data. Open the Gemini side panel → "What are the top 5 categories by total sales?" Gemini writes the formula and highlights the result.
3. Smart Fill. Type a pattern in one cell (e.g. extract first name), press Ctrl + Shift + Y, and Sheets fills the entire column.
4. Formula help. Start a formula with = and a description — "=total of column B where column C equals 'Paid'" — Gemini suggests the SUMIF.
5. Connected Sheets + BigQuery. Query billions of rows directly in Sheets without SQL knowledge; Gemini writes the SQL for you.
