On October 28, 2026, Google announced web sources for individual cells populated with the AI function in Sheets on the web. Rollout began October 20 and may take up to 15 days; the announcement date is not the start date.

Who benefits

Small-business teams compiling public information in a spreadsheet. An illustrative example is a list of prospective suppliers’ delivery terms. A citation helps open the source of a particular answer, but does not establish that the answer is correct. This is an editorial scenario, not a tested case study.

How to review it

Google’s help page describes the path: click a cell, hover over its content and choose Sources.

Our editorial recommendation:

  1. Start with a small copy of the spreadsheet without confidential data.
  2. Open the cited source and find the passage supporting that specific claim.
  3. Check the date, region and exceptions. General delivery availability, for example, does not establish delivery to your city.
  4. Record the review date and responsible person. Keep unverified cells marked rather than passing them on as agreed facts.

Access and limits

Supported plans include Business Standard and Plus, with Gemini in Sheets enabled. Check the individual employee’s access. The AI function returns text and cannot access the entire spreadsheet or other Drive files; context must be supplied separately.

Capacity documentation differs: the announcement says up to 3,000 cells per request, while help specifies the first 350 selected cells containing AI functions. We have not confirmed the actual limit; do not plan bulk filling around the larger number without checking.

The takeaway: use the new links to review data, not as automatic approval. We have not tested account access, Ukrainian-language operation or accuracy in a working account.
