Claude for Sheets is an Artificial Intelligence driven assistant that integrates with Google Sheets, provided by Anthropic. It leverages the capabilities of Claude, Anthropic's AI, within spreadsheets adding a new dimension of functionality.

To use this tool, an Anthropic API key is required. This AI assistant can be incorporated into the spreadsheet environment by adding the Claude for Sheets extension.

It introduces two specific formula functions known as =CLAUDE() and =CLAUDEFREE(). The =CLAUDE() function is generally used to converse with Claude directly within the spreadsheet.

On the other hand, =CLAUDEFREE() is utilized for sending free-form prompts to Claudes API, mirroring the function of a direct API call. The tool enables the extraction of specific information from text, translation, text rewriting in various styles, content summary, data classification, etc.

It also assists in removing identifiable information and can be employed to simulate real-life roles such as a career coach, among other applications.

Assuring data privacy, data shared with =CLAUDE functions are exclusively shared with Anthropic as outlined in their Privacy Policy. Sharing a Claude for Sheets spreadsheet with other users within your Google Workspace organization enables the users to use the custom functions without needing to install the add-on separately.
