CalcLM

CalcLM is a prototype that brings agentic AI into the familiar grid interface of Excel. Users express agent steps as formulas, chain tasks across cells, and explore how multi-step agent workflows can flow over a spreadsheet-like surface. The system uses Azure OpenAI GPT-4.1 to interpret formula-like specifications and execute multi-step workflows within grid cells, bridging the gap between traditional spreadsheet idioms and emerging agentic capabilities.

By embedding agent orchestration into Excel’s grid model, CalcLM explores a route to making agents accessible to non-developer spreadsheet users — orders of magnitude more people than those who currently write Python notebooks or LangChain pipelines. The prototype lets users iterate on agent workflows by directly manipulating cells, with no separate configuration UI or code. It is explicitly an experiment in productivity-UX rather than a production product, but it points at a serious thesis: that the next generation of productivity tools may be reimagined around agent-powered automation expressed in familiar interfaces.
