Your Google Sheets can now analyze data and manipulate content using Claude's AI through custom formula functions. Claude for Sheets turns spreadsheets into powerful AI workstations — no need to leave Google Workspace.
The add-on delivers three main functions that connect directly to Anthropic's API. =CLAUDE() works exactly like chatting with Claude on claude.ai. =CLAUDEMESSAGES() handles back-and-forth conversations using proper message formatting. =CLAUDEFREE() exists for legacy text completion tasks.
A marketing manager analyzing customer feedback could use Claude functions to classify responses by sentiment. Extract key themes. Generate summary reports. All within the same spreadsheet. Functions handle everything from PII removal to translation and content rewriting in specific styles.
Smart caching reduces API costs automatically.
Background recalculation prevents hitting concurrency limits when you're working with sheets full of Claude cells. You'll get 233,000+ users getting the add-on free, but you'll need your own Anthropic API key. That means separate billing at normal Anthropic rates for each function call. Shared spreadsheets let teammates use your Claude functions without installing anything themselves (though they're still using your API credits).
Data analysts can chain prompts together for complex workflows. Content creators too. Operations teams love it. Extract emails from messy data. Translate product descriptions. Get document Q&A with citations. Your API key handles the heavy lifting while Google Sheets manages the results.
