Fill with Gemini now shows the web source behind each individual cell in Google Sheets, and takes up to 3,000 cells per request. Rolling out from October 20 on listed editions.
Generating an enrichment column has never been the hard part. Trusting it has. Five hundred companies with a headcount band and a funding line take minutes to fill and an afternoon to doubt, and the doubt is why so many enriched lists sit unused next to the tab they came from. Per-cell sources change the unit of checking from the column to the cell: open the three rows that look wrong, read what Gemini used, fix those rows, send the rest. The limit is as plain as the gain. A citation tells you what Gemini read, not that the value is right, and Google's speed figure is its own internal study of its own feature. The number worth repeating to a manager is how many cells you rejected out of a twenty-row sample of your own list.
"Fill with Gemini" is the Sheets feature that writes values into a range of empty cells for you, instead of you researching each row by hand. A "citation" here is the web page Gemini used for one specific cell, shown inside that cell rather than at the bottom of the column.
"Gradual rollout" means Google switches it on for accounts in batches; the post says up to 15 days from October 20 before you see it. "Rapid Release" and "Scheduled Release" are the two speeds a Workspace domain can be set at, and your admin chose one years ago. "Available by default to users with Gemini in Sheets enabled" means there is no new setting for citations: if Gemini in Sheets works for you, this comes with it.
The short version: Sheets can now show which web page each filled-in cell came from, up to 3,000 cells per request, so you can check the few rows that look wrong instead of re-researching the whole column.
Google announced on October 28, 2026, on the Google Workspace Updates blog, that Fill with Gemini in Google Sheets now shows the web sources behind each generated value: "Gemini will now provide the exact web sources referenced directly within each individual cell." The same post raises capacity, with "expanded capacity supporting up to 3,000 cells per request."
Announced: October 28, 2026, on Google Workspace Updates.
Availability: "Gradual rollout (up to 15 days for feature visibility) started on October 20, 2026" for Rapid Release and Scheduled Release domains. Editions named: Business Standard and Plus; Enterprise Standard and Plus; Google AI Pro and Ultra; Google AI Pro for Education; AI Expanded Access.
Price: Not stated beyond the plan you already have.
Regions: Not stated.
There is no new switch to find: "This feature will be available by default to users with Gemini in Sheets enabled." Google states the sources are available in Google Sheets on the web, and points users to the Gemini side panel or the Ask Gemini button in the top right corner of Sheets. Google's own figure of "up to 55 times faster than manual entry for 500 cell tasks" is footnoted to an internal 95-participant study of its own feature.
What it doesn't do: A citation records what Gemini referenced for that cell; it is not a check that the value is right. The post does not say which web sources are eligible, how recent they are, or what happens when two sources disagree. Google reports faster responses and better cell-over-cell consistency without a figure for either. No mobile or desktop path for the sources is stated, no price is named, and no region list is given. Promptifi has not reproduced the feature: this is a researched reading of Google's page, not an observed result.
SDR - Fill one column per request, with the header naming the exact fact rather than a topic, and keep a domain column so Gemini identifies the right company. Then open the citation on every blank cell and every company whose name is shared by someone else, before the list reaches a sequence. Count the cells you reject; that count, not any vendor figure, tells you whether this list is clean enough to send.
AE - Use it for the account facts you would otherwise ask someone to look up before a first call: HQ country, most recent funding, a parent company. Read the source on anything you plan to say out loud to a buyer. A cited wrong value is still a wrong value, and the citation makes it both easier to catch and easier to trust by mistake.
Manager - This arrives by default wherever Gemini in Sheets is enabled, so your team may have it before you have a view on it. Ask for the rejected-cell count on one real list rather than a demo, and make reading citations part of the hand-off from list to sequence. Google's 55-times figure is its own internal study; do not let it set anyone's expectation.
RevOps - There is no separate admin control, so eligibility is the edition list plus whether Gemini in Sheets is on; check your seat mix against both. Sources are stated for Sheets on the web only, which means part of the team will not see them where they work. Decide whether a generated column may be imported to the CRM at all, and if so, require an inspected sample first. Google's post says nothing about source quality, recency, or conflicts between sources.
A cited column is only as good as the instruction that produced it. Run Research a Prospect Using Google Workspace by hand on three companies from the same list, then compare its output against the cells Gemini filled. Where the two disagree, the citation tells you which one to keep.
