If your business runs on Google Sheets, and many of the businesses we build for do, this one is worth a few minutes. On October 6, 2026, Anthropic released Claude for Google Workspace, an add-on that opens Claude in a sidebar inside Google Docs, Google Sheets and Google Slides. It is in public beta on every paid Claude plan.
The important part is where it works. Until now, using an AI assistant on a spreadsheet meant copying data into a chat window, asking a question, and pasting the answer back. The add-on removes that round trip: Claude reads the file you have open and makes changes directly in it.
What Claude can do in each app
Google Docs
Claude edits the document in place. Anthropic says it can fix a sentence or restyle a heading without touching the surrounding formatting. That matters more than it sounds, because most AI rewrites break bullet styles, heading levels and spacing on the way back in. Larger changes, such as tightening a summary or turning a block of text into a table, appear as suggestion cards in the sidebar for you to accept or reject.
Google Sheets
This is the part most relevant to small businesses. In Sheets, Claude can:
- Write formulas from a plain-English request
- Build pivot tables and native Sheets charts
- Add new tabs
- Pull a range into Python for cleaning or analysis, then write the results back into the sheet
For a shop owner who knows the totals are somewhere in the sales tab but has never written a SUMIFS, that removes a real barrier. Asking "show monthly sales by product as a chart on a new tab" becomes a request, not an afternoon of tutorials.
Google Slides
Claude builds new slides from your deck's existing layouts and theme, so the result still looks like your deck. It can also flag elements that overlap, run off the slide, or contain text that is hard to read.
You stay in control of the edits
The add-on has two modes. Ask before edits is the default: every change waits for your approval. Accept all edits lets ordinary changes go through on their own. For any sheet that holds real money, such as fees, payments or stock, keep the default. Reviewing each change takes seconds, while a confident wrong formula pasted down a column can quietly misreport numbers for weeks.
Working from the Claude app instead
Alongside the add-on, Anthropic released Google Docs, Sheets and Slides connectors, also in beta. These work the other way round: from a normal Claude chat, you can paste a link to a Google file, or ask for a new one, and Claude creates or edits it without you opening the file first. The sidebar is for working inside one file; the connectors are for when the conversation is the starting point.
How to install it
- Install Claude for Google Workspace from the Google Workspace Marketplace. It needs a paid Claude plan.
- Open any Doc, Sheet or Slides file and go to Extensions > Claude > Open Claude.
Workspace administrators can also deploy it from the Google Admin console, either to the whole domain or to selected groups. For Enterprise customers, Anthropic says the add-on falls under the controls they already use, including the Compliance API, customer-managed encryption keys and OpenTelemetry audit export.
Beta limits worth knowing
This is a beta, and Anthropic's help article lists a few limits:
- Browsers: Chrome, Edge and Safari are supported. Firefox is not; the sidebar loads, but operations do not complete.
- What it can see in Docs: Claude cannot see images, comments or suggestions in a document. Paste comments into the chat if you want it to act on them.
- Long jobs: a single operation can run for at most six minutes before Google stops it, so split very large clean-up jobs into smaller ranges.
What it does not replace
An assistant that writes better formulas makes a spreadsheet easier to work with. It does not turn the spreadsheet into a system. The weak points that push growing businesses off spreadsheets are still there:
- No real permissions. Anyone who can edit the sheet can still change or delete any row, including the ones they should never touch.
- No enforced rules. Claude can clean messy data after the fact, but nothing stops the next person from typing a date as text or a quantity with a comma.
- No workflow. "Pending" and "approved" are still just words in a cell, with the actual approval happening somewhere else.
- No audit trail. Version history shows that something changed, not a clear record of who approved what and when.
In short: spreadsheets are excellent for analysis and fragile as shared operational systems. Claude makes the analysis side much stronger. The operational side still needs logins, roles, validated forms and a log.
The practical way to use both
The two fit together well. A Google Sheets-backed web app built with Apps Script keeps your data in a sheet you own, while staff work through forms and dashboards with proper roles and an activity log. That data is still an ordinary Google Sheet, so Claude can sit beside it for the work it is good at: one-off analysis, a pivot table for a meeting, a chart for the month-end report, or cleaning up an import before it goes in.
Put simply, the app runs the daily operations and the sheet holds the data, so Claude can help you understand it.
Should you try it?
If you already pay for Claude and spend real time in Google Sheets, yes. Install it, keep Ask before edits switched on, and start with a read-only question about a sheet you know well, so you can judge the answers against numbers you already trust. If the spreadsheet itself has become the problem, with too many people, too many tabs and too many "final" copies, an AI sidebar will not fix that. A small, purpose-built system will. You can browse free Apps Script and PHP source code to see what that looks like, or see custom development if you need one built around your process.
