Sommelier
Excel add-in that connects your spreadsheets to a personal AI agent
Visit sommelier.grokked.it ↗What is Sommelier?
Sommelier is an open-source Excel add-in that lets you pair your spreadsheet with an AI agent of your choice. Instead of relying on Microsoft Copilot, you can use a local model, a personal harness, or any agent with shell access. The add-in enables your agent to interact with your workbook—inspecting cell values, suggesting edits, and generating visualizations—all within Excel itself.
Designed for users who prioritize data privacy or want to use custom AI setups, Sommelier encrypts workbook traffic between Excel and a local bridge, ensuring your data stays under your control. The maker reports the code was rewritten by an LLM after establishing the core architecture. Installation is manual via XML manifest sideloading, and it requires Node.js 22.12+ to run the relay server.
