While many are familiar with AI models like ChatGPT or Gemini, another potent AI model gaining traction is Claude AI, developed by Anthropic. Claude AI excels at responding to prompts, retrieving information, and executing various tasks. Notably, it seamlessly integrates with Google applications such as Google Sheets and Docs.

In Google Sheets, Claude AI assists in generating prompt responses, recalculating cell data, and configuring assistant and user messages. To harness Claude AI within Google Sheets, you need to utilize the Claude API. Here's how you can incorporate this AI model into your Google Sheets.

Generating a Claude API Key

To use the Claude for Sheets extension, you'll require a developer API key from Anthropic. Even if you possess a user account for Claude, signing up separately for the Claude API is necessary.

Step 1: Visit Anthropic's website through this link and sign up using your email address or log in with your Google account.

Step 2: After entering your email, a verification code will be sent to your inbox. Enter the code, provide your name, and confirm you're at least 18 years old to proceed.

Step 3: You'll be prompted to furnish details about your organization. Fill in the information and click 'Create Account'.

Step 4: Although you can start using Claude AI immediately, to integrate it with Google Sheets, click on the 'Get API Keys' button on your dashboard.

Step 5: Click on 'Create Key', and a pop-up will prompt you to name your key. Provide a descriptive name like 'Claude For Sheets'.

Step 6: After naming your key, click 'Create Key' to generate it.

Step 7: A notification will confirm that your API key has been successfully created. Copy this key and store it securely, as you won't be able to view it again.

Note: Your API key is akin to a password and should be kept confidential. Avoid sharing it publicly to prevent unauthorized access.

Step 8: To effectively use Claude AI with Google Sheets, you'll need some credits or a paid plan. You can claim $5 in free credits or choose a suitable paid plan by clicking on the 'Upgrade' button.

Installing the Claude for Sheets Extension

To integrate Claude AI into Google Sheets, you need to install the Claude for Sheets extension.

Step 1: Open Google Sheets and click on the 'Extensions' menu at the top.

Step 2: Hover over 'Add-ons' and select 'Get add-ons' from the submenu.

Step 3: In the search bar, type 'Claude for Sheets' and click on the extension when it appears.

Step 4: Click 'Install' to add the extension to your Google Sheets.

Note: You'll need to grant access to your Google account to use the extension. Be aware that Google will share necessary details with Claude AI upon granting access.

Step 5: After granting permission, a notification will confirm the successful installation of the Claude for Sheets extension.

Step 6: Before using the extension, you must enter your API key. Go to the 'Extensions' menu, select 'Claude for Sheets', and then click on 'Enter Your Anthropic API Key'.

Step 7: Paste your API key into the pop-up window and click 'OK'.

Step 8: A confirmation message will appear, indicating that your API key has been saved successfully. The Claude for Sheets extension panel will now be visible on the right side of your screen.

You are now ready to use Claude AI within Google Sheets.

Note: Although the Claude for Sheets extension is free, it operates using your Anthropic API key. Any API calls made will be charged based on your Anthropic plan. Exercise caution when sharing sheets that include the add-on.

Sharing Sheets with Claude for Sheets Extension Added

If you share sheets with the Claude for Sheets extension enabled with others in your Google Workspace organization, they can utilize its functions without installing the extension themselves. While they won't have access to your API key, the extension can still make API calls using it, and any associated charges will be billed to your account.

However, if collaborators attempt to access the Claude for Sheets menu, they will be prompted to install the add-on first. When sharing the sheet with individuals outside your organization, they can interact with the functions but won't see the Claude for Sheets menu unless they install the extension.

Using Claude AI

There are several ways to leverage Claude AI in Google Sheets. One of the simplest methods is using the CLAUDE() function, which allows you to input a prompt as plain text and have the AI perform a specified task.

Looking Up Information

With Claude AI, you can quickly retrieve information using the CLAUDE() function. Input your prompt enclosed in quotation marks and parentheses following =CLAUDE.

Step 1: For example, to find the capital of the Netherlands, type =CLAUDE("What is the capital of the Netherlands?") into a cell or the formula bar.

Step 2: Press the Enter key, and Claude AI will provide the answer directly in the cell.

Recalculating Cells

Claude AI can assist in recalculating cells labeled as 'Error', 'Deferred', or 'Throttled' to ensure data accuracy.

Step 1: Select the cells you wish to recalculate in your spreadsheet.

Step 2: In the Claude for Sheets extension panel on the right, click the 'Recalculate' button to view options.

Step 3: Choose whether to recalculate the entire sheet or only the selected cells. Click 'Deferred/Throttled/#Error: Cells' to initiate the recalculation.

Step 4: Claude AI will process and update the selected cells accordingly.

Sending User and Assistant Messages

The CLAUDEMESSAGES() function enables you to send user and assistant messages to Claude AI. You can enter multi-line inputs using shortcuts like Alt + Enter on Windows or CMD + Enter on Mac.

Step 1: Use the function as follows: =CLAUDEMESSAGES("User: In one sentence, what is good about the color blue? Assistant: The color blue is great because").

Step 2: Press the Enter key (or Return on Mac), and Claude AI will complete the assistant's response.

Step 3: To use CLAUDEMESSAGES() with a system prompt and specify a model name, input: =CLAUDEMESSAGES("User: Got anything to say to me? Assistant:", "claude-2.0", "system", "You are a cow who loves to moo in response to any and all user queries.").

Step 4: Press Enter, and Claude AI will generate a response based on the system prompt provided.


Claude AI is a highly versatile AI model that, when integrated with Google Sheets, expands its capabilities, allowing you to perform tasks more efficiently. From handling prompts to recalculating cell data, Claude AI enhances your spreadsheet experience. While you can start with free credits to explore its features, investing in a paid plan unlocks the full potential of this powerful tool.
