## Key takeaways

- Google announced on October 28 that Gemini in Google Sheets now shows the web sources for each cell it generates, on Sheets for the web.
- A single request can now cover up to 3,000 cells, and Google says processing is faster and more consistent.
- The rollout began October 20 and can take up to 15 days to reach users on Business, Enterprise, Google AI Pro and Ultra plans.

Google now shows the web sources behind each cell that Gemini fills in Google Sheets. The change, announced on the [Google Workspace Updates blog](http://workspaceupdates.googleblog.com/2026/10/fill-with-gemini-now-provides-cell-level-citations-for-web-sources-and-supports-larger-requests.html) on October 28, applies to Gemini in Google Sheets when it generates values with the AI function, and a single request can now cover up to 3,000 cells.

The citations matter because Gemini in Sheets is most useful for bulk work, such as filling in a column of facts about a list of companies or cities. A column of AI-generated values is hard to trust if you can't see where each one came from. Per-cell sources let you spot-check a number instead of redoing the research.

## What changed in Fill with Gemini

Google says the AI function, which generates, summarizes or categorizes values inside cells, now shows the specific web sources Gemini used for each output. They are attributed to the individual cell, not to the whole request, so you can audit and cross-check one result at a time. Sources are available in Sheets on the web.

Google also says it upgraded the processing behind the feature. Results come back faster and are more consistent from one cell to the next. A request can now cover up to 3,000 cells, so you can summarize or categorize a larger block of data in one go.

The AI function takes a prompt and an optional range of cells, written as `AI("prompt", range)`. Google's [help page for the function](https://support.google.com/docs/answer/15877199) says it can also pull current information from Google Search. That page still lists a limit of 350 selected cells generated at once, so it appears not to reflect the new 3,000-cell figure yet. We have not tested the larger limit.

## The speed claim

Google says Fill with Gemini can be up to 55 times faster than manual entry on a 500-cell task. The footnote says this comes from an internal study of 95 participants, using English prompts and English-language users. It compares Gemini with typing the data by hand, not with other tools, and Google has not published the study itself. Treat it as a marketing figure.

## Who gets it and when

The rollout began on October 20 for Rapid Release and Scheduled Release domains, which are Google's two release tracks for Workspace admins. It is gradual, and the feature can take up to 15 days to appear. Google lists these plans:

| Group | Plans |
| --- | --- |
| Business | Business Standard and Plus |
| Enterprise | Enterprise Standard and Plus |
| Consumer | Google AI Pro and Ultra |
| Education add-on | Google AI Pro for Education |
| Other add-on | AI Expanded Access |

The feature is on by default for users who already have Gemini in Sheets enabled. Admins control that through Google's [help article on managing access to Gemini features](https://support.google.com/a/answer/15698295). To use it, open the side panel by clicking the "Ask Gemini" spark button in the top right of Sheets.

## What we don't know yet

Google doesn't say how many sources each cell shows, or how it decides which pages count as a source. A citation shows where Gemini looked. It doesn't prove the cell's value is right, so the checking is still yours. The post also says nothing about citations on mobile or in the desktop Sheets apps.

Google's weekly recap of October 23 lists related Sheets changes from the same week, including Gemini in Sheets on iOS and natural-language analysis of BigQuery data. Check the sources on a sample of cells before you rely on a whole column.
