calculation graph

About this tag
The calculation graph tag on WindowsForum covers discussions about how modern Excel formulas now integrate AI-driven outputs as first-class results. Recent threads highlight Microsoft's Copilot function, which allows plain-English prompts to generate live, spillable results that update automatically with data changes. This marks a shift from purely deterministic spreadsheet logic to a hybrid environment where probabilistic AI outputs coexist with traditional formulas. Topics include the technical implications of treating AI results as formula cells, the behavior of calculation graphs when mixing deterministic and probabilistic dependencies, and the impact on spreadsheet performance and debugging. The tag is relevant for users exploring advanced Excel features in Microsoft 365 Copilot on Windows and Mac.
