Copy-paste Claude formulas for the Google Sheets add-on
Paste a formula into row 2, test it on a few rows, then drag down to run the workflow across your spreadsheet.
Run Claude in a cell
A: input cell
=GPT("Summarize the following in one clear sentence: " & A2)
Enrich a company
A: company · B: notes · C: offer
=GPT("Research this company for outreach: " & A2 & ". Notes: " & B2 & ". Offer: " & C2 & ". Return a short summary, likely industry, and one relevance signal. If unsure, say Needs manual research.")
Classify a row
A: text · B: categories
=GPT("Classify this text into exactly one of these categories: " & B2 & ". Text: " & A2 & ". Return only the category, or Unclear.")
Fit score 1-5
A: account · B: ICP · C: source text
=GPT("Score 1-5 for ICP fit. Account: " & A2 & ". ICP: " & B2 & ". Source: " & C2 & ". Return score, reason, confidence, and what to verify.")
Short answer
There is no official Anthropic plugin built by Anthropic for Google Sheets, but you can run Claude inside Google Sheets through a third-party add-on. The most common way is GPT for Sheets: install the add-on, select Claude (Anthropic) as your model, add a key if prompted, and then call Claude from a spreadsheet formula such as =GPT(…). Filling the formula down runs Claude across every row.
Fastest path: Install GPT for Sheets → select Claude → paste a formula from the formula section → review 10 rows → fill down the sheet.
This page is for analysts and sales or ops teams checking whether Claude can run inside Sheets before they commit to a workflow. People search for a “plugin,” “add-on,” or “extension”; in Google Workspace the accurate term is add-on.
How the add-on works
GPT for Sheets is a Google Workspace add-on that adds AI functions like =GPT(…) to your spreadsheet. When you select Claude as the model, those functions send your prompt to Claude and write the response back into the cell. Because it is a formula, the same prompt runs consistently across hundreds of rows, and your inputs stay visible next to the outputs for review.
| Step | What happens | Why it matters |
|---|---|---|
| Install | Add-on appears under Extensions | No code or separate app needed |
| Select model | Choose Claude (Anthropic) | Runs Claude rather than another provider |
| Add key | Paste your Claude API key if prompted | Lets the add-on call Claude on your behalf |
| Write formula | =GPT(“…”) in a cell | Turns a prompt into a fillable function |
| Fill down | Drag the formula across rows | Runs Claude across your whole list |
Install and add your Claude key
- Install GPT for Sheets from the Google Workspace Marketplace.
- Open it from the Extensions menu and choose Claude (Anthropic) as the model.
- Add your Claude API key in the add-on settings if you are prompted for one.
- Test with
=GPT("Say hello"), then paste a workflow formula and fill it down.
Add-on vs copy-pasting from the chat window
Pasting a single cell into the Claude chat app works for one row but breaks down across a list. The add-on turns Claude into a fillable formula, so the same instruction runs over hundreds of rows with inputs you can audit. You can also switch the selected model per run to compare Claude with GPT or Gemini on the same data.
Use cases
- Enrichment: add context to companies or contacts across a list.
- Cleanup: normalize messy names, titles, and exports.
- Classification: tag rows by industry, intent, or category.
- Scoring: rate fit with a reason and confidence.
- Drafting: write summaries, openers, or replies per row.
Best for / not best for
Best for: anyone who wants Claude available as a spreadsheet function to process many rows inside Google Sheets without writing code.
Not best for: teams that need a guaranteed proprietary data source, or that want to act on outputs without any review.
Using the add-on is the right move when your data already lives in Sheets and you want repeatable, reviewable Claude output across rows. For a single one-off answer, the chat window is fine.

Safety, compliance, and data quality
Treat Claude output as a draft. Keep source columns visible, verify important claims, and do not infer sensitive attributes. Use lawful data and follow consent and deliverability rules for any outreach generated in the sheet. “Claude” and “Anthropic” are trademarks of their owner; this add-on is unaffiliated with Anthropic, and a Claude API key may be required.
