Snowflake released CoCo for Microsoft Excel and Google Sheets in public preview, delivering an AI-powered add-in that pipes live Snowflake data into spreadsheets while enforcing enterprise access controls, masking, and row access policies1. CoCo can build pivot tables beyond Excel's one-million-row limit by offloading computation to Snowflake virtual warehouses and call Cortex AI functions directly in cells. Internal benchmarks run between Oct. 26 and Oct. 28, 2026, using Claude Opus 5.5, Claude Sonnet 5.5, and Claude Haiku 5.5 showed CoCo for Excel matched an MCP-based AI harness on accuracy while achieving lower latency and fewer output tokens.
