Abstraction of formulas into reusable functions

Abstract:

A formula abstraction system is described. The system includes detecting a user-generated formula in a cell of a spreadsheet document, generating a graphical user interface that queries entries of a custom function based on the user-generated formula, forming the custom function by abstracting the user-generated formula to the custom function based on the entries, and storing the custom function in a function library of the spreadsheet document. The custom function applies the user-generated formula in a user-selected cell of the spreadsheet document.
