The visible spreadsheet is only part of a connected analysis. Check the underlying query and the refreshed result before relying on a generated dashboard.
Gemini can work across the connected dataset
Google’s October 19 announcement adds conversational analysis of BigQuery data through Connected Sheets. Queries use the connected dataset, not only the rows displayed in the spreadsheet.
Gemini can propose a plan, then create a tab containing connected formulas, pivot tables and charts. Google describes these as native objects that can be refreshed, rather than a fixed picture of an answer.
Check rollout and account eligibility
Google lists Business Standard and Plus, Enterprise Standard and Plus, Google AI Pro and Ultra, Google AI Pro for Education, and AI Expanded Access. The gradual rollout can take up to 15 days from October 19.
The announcement says the feature is on by default without a dedicated admin control. Users still need permission to query the connected BigQuery data. Neither a shared spreadsheet link nor an eligible plan alone establishes that access.
Start with an aggregate you already know
For a sales dashboard, define the revenue field, reporting period, time zone, and treatment of refunds before asking a natural-language question. Keep a known BigQuery result for comparison.
Ask Gemini for a plan and inspect the intended filters before accepting the generated dashboard. A plausible answer can still count the wrong rows or use a different definition of revenue.
- Compare the first total with the known query result.
- Check grouping, date boundaries, and excluded records.
- Inspect the native formulas, pivots, and chart labels.
- Confirm which account can query and refresh the connection.
- Refresh after a controlled source-data change.
- Verify that the displayed result and refresh time match expectations.
Keep access and freshness visible to the reviewer
A correct result today can become stale. Save the data source, filter definitions, and refresh behavior beside the dashboard so the next reader can interpret it.
I would use one small connected report for the first trial. Check that the intended reviewer can inspect its assumptions and that a refresh produces the expected change. This is a proposed acceptance test; we have not measured the feature’s accuracy or time savings.
Our BigQuery TabFM guide covers a separate prediction feature. The Workday Sheets article addresses a different connected workflow.

Checked October 20, 2026. This is source-based reporting and analysis; proposed checks are not hands-on test results.
