How to Use Claude in Google Docs, Sheets, and Slides

Ellie at Willa, Editorial lead, Willa · Published October 8, 2026 · Updated October 8, 2026

If you spend your workday in Google Docs, Sheets, and Slides, you can now keep Claude open right beside your file. On October 6, Anthropic launched Claude for Google Workspace, a sidebar add-on in public beta that reads the file you have open, talks through what you want, and makes the edits itself: rewriting sections, fixing formulas, building slides. VentureBeat's coverage notes it works in the other direction too, since new beta connectors let you open and edit Google files from inside a Claude chat.

We wrote a similar guide when ChatGPT arrived in Microsoft Word, and the same thing is true here: the end of copy-paste is a bigger deal for non-technical professionals than almost any model release. Here is how to set it up, what it can and cannot do during the beta, and five workflows worth trying in your first hour.

What is Claude for Google Workspace?

It is an official add-on from Anthropic that puts Claude in a sidebar inside Google Docs, Sheets, and Slides. Claude can read the open file, see the text or cells you have selected, answer questions about the content, and make changes directly in the file. According to Anthropic's help center, every edit shows up in the file's version history under your name, so anything Claude does can be undone the same way you would undo your own work.

Two details matter for anyone cautious about connecting AI to work files. First, the add-on asks for only two Google permissions: one to run the sidebar and one to access the file you currently have open. It does not get access to your Drive, Gmail, or Calendar. Second, by default Claude describes each change and waits for you to approve it before touching anything.

How do I install the Claude add-on in Google Docs?

One install covers Docs, Sheets, and Slides. The whole setup takes about five minutes:

1. Install Claude from the Google Workspace Marketplace (search for "Claude" or follow the link from Anthropic's announcement).
2. Open any Doc, Sheet, or Slides file and go to Extensions, then Claude, then "Open Claude."
3. Approve the two permissions Google shows you on first use.
4. Sign in with your Claude account in the sidebar.
5. Ask your first question about the file.

If you use a company Google account and see "This application is not allowed by your administrator," you cannot fix that yourself. A Workspace admin has to allowlist or install the add-on, and admins can roll it out to the whole organization or specific groups. Worth forwarding this post to whoever runs IT.

Do I need a paid Claude plan?

Yes. The add-on itself is free to install, but the beta works with paid Claude plans only: Pro, Max, Team, and Enterprise. There is no separate charge for the add-on; usage comes out of your existing plan. If you have been on the free tier and wanted a concrete reason to upgrade, working inside your actual files is a better one than most.

What can Claude do in Docs, Sheets, and Slides?

In Docs, Claude handles the editing jobs that eat an afternoon: rewriting and shortening long documents, restructuring sections, turning rough notes into tables, checking for terms you used but never defined, and fixing inconsistent headings and numbering. Anthropic says it can correct a single sentence without disturbing the formatting around it, and for bigger rewrites it can propose changes as suggestion cards you accept or reject one at a time.

In Sheets, Claude explains what a formula does in plain language, writes and fixes formulas, flags hardcoded values hiding in your calculations, normalizes messy data, builds models on new tabs, and creates pivot tables and native charts. For heavier jobs like joining two datasets or cleaning a large range, it can process the data in Python behind the scenes and write the results back into the sheet. You never see the code unless you ask.

In Slides, Claude drafts new slides using your deck's existing layouts and theme, splits dense slides into two, makes titles consistent across the deck, and restyles the whole thing. It can also review its own work and catch overlapping elements, text that runs off the slide, and hard-to-read color contrast, which are exactly the things you normally catch five minutes before presenting.

In all three apps you can attach up to 20 reference files to a message, and there is a web search toggle, off by default, for when Claude needs current information.

Should Claude ask before every edit?

The sidebar has two modes, and the right choice depends on the file. "Ask before edits" is the default: Claude describes each planned change and waits for you to click Allow. "Accept all edits" lets Claude apply ordinary content changes without pausing, which is much faster for big jobs like restyling a 40-slide deck.

Our advice: stay on "Ask before edits" for your first few sessions and for anything client-facing or shared, then switch to "Accept all edits" for drafts and internal files once you trust the output. Some guardrails hold no matter which mode you pick. Claude always asks before adding links, inserting images from the web, or removing anyone's access to a file, and those requests carry a "Security review" label with no option to always allow. It cannot share files, change ownership, or create automations at all.

How is this different from Claude Docs or Gemini?

Claude Docs and Claude Slides, which we covered in our beginner's guide, are Anthropic's own document and presentation tools that live inside the Claude app. This add-on is the reverse: Claude comes to Google's apps, where your team's files already live. If your collaborators comment, share, and track everything in Workspace, the add-on fits your life better than asking everyone to meet you in Claude.

Google's own Gemini is already built into Workspace for many accounts, so the practical difference is which assistant you prefer and which one you already pay for. If Claude is where your prompts, projects, and skills live, you no longer have to give that up inside a Google file: the sidebar uses the same models and connectors as your regular Claude account.

5 workflows to try in your first hour

1. Clean up meeting notes. Open the messy Doc, then ask: "Restructure these notes with clear headings, turn the action items into a table with owner and due date columns, and flag anything with no owner."
2. Audit a spreadsheet you inherited. In the Sheet: "Explain what the formulas on this tab do, and flag any hardcoded values I should know about." This is the fastest way to understand a file someone else built.
3. Split an overloaded deck. In Slides: "Find the three densest slides, split each into two using this deck's layouts, and make all the titles consistent."
4. Turn a Doc into a first-draft deck outline. Ask Claude in your Doc to condense a project brief into a slide-by-slide outline, then paste it into Slides and have Claude build from there (the beta works on one open file at a time, so this takes two steps).
5. Build a chart without touching a formula. In Sheets: "Summarize this data in a pivot table on a new tab and add a chart showing the monthly trend."

What are the beta limitations?

A few things to know before you rely on it. The sidebar works only on the file you have open, and you need to keep it open while Claude works. Long operations time out at six minutes, so split big jobs into steps. Supported browsers are Chrome, Edge, and Safari, not Firefox. In Docs, Claude cannot read or reply to comments and its edits are direct rather than suggestions. In Sheets, it cannot touch Connected Sheets (BigQuery) tabs. In Slides, charts it creates are static images that will not update when the source data changes. And chat history is stored per file in your browser, so it does not follow you across devices.

None of these are dealbreakers for everyday work. They are just the difference between a beta and a finished product, and the list will likely shrink.

Key takeaways

• Claude for Google Workspace launched in public beta on October 6, 2026, and puts Claude in a sidebar inside Docs, Sheets, and Slides.
• One free add-on from the Google Workspace Marketplace covers all three apps, but you need a paid Claude plan (Pro, Max, Team, or Enterprise) to use it.
• It only sees the file you have open, asks before editing by default, and every change lands in version history so you can undo it.
• The strongest early use cases are document cleanup, formula help and data auditing in Sheets, and deck restyling in Slides.
• Beta limits to plan around: one file at a time, six-minute operations, no Firefox, and static charts in Slides.
