What changed: Google says Fill with Gemini in Sheets now attributes the exact web sources used to generate each cell value, letting users audit AI-generated data cell by cell. The update also speeds up processing by up to 55 times for 500-cell tasks compared to manual entry, and raises the per-request limit to 3,000 cells.
Who is affected
Businesses on Google Workspace Business Standard/Plus, Enterprise Standard/Plus, plus Google AI Pro/Ultra, Google AI Pro for Education, and AI Expanded Access subscribers with Gemini in Sheets enabled.
What it means for your business
For businesses using Google Sheets, this means AI-generated figures can now be checked cell-by-cell against their web sources, and larger datasets of up to 3,000 cells can be processed in a single request.
What to do
Open the 'Ask Gemini' panel in Sheets and review the per-cell source citations before relying on AI-generated values; batch larger data tasks into a single request of up to 3,000 cells to save time.
When it takes effect
Gradual rollout began October 20, 2026, with visibility taking up to 15 days to reach all eligible accounts.
