The present invention extends to methods, systems, and computer program products for creating text functions form a spreadsheet. Embodiments of the invention extract functions from spreadsheets and represent the functions in textual form. Representation in textual form promotes code reuse, clarify, expressive power, and better performance. Text can be rendered in virtually any programming language, such as, for example, C#, C++, Visual Basic (“VB”), etc. In some embodiments, programming language extensibility to support spreadsheet compatible data types and functions is utilized.
