Funcalc is an extension of Corecalc in which users can define their own functions via sheet-defined functions, without resorting to external languages such as VBA. These are compiled to .NET bytecode at run-time, thus offering high performance while preserving the usual mode of interaction in which all edits take effect immediately. Funcalc is a research prototype.
