Systems, methods, and software are disclosed herein for enhancing functions and formulas in spreadsheets. A computing apparatus detects a beginning of a formula in a cell of a spreadsheet. In response to detecting the beginning of the formula, the computing apparatus identifies a vector representation of a context of the cell and supplies the vector representation as input to one or more machine learning models. The one or more machine learning models produce output comprising one or more suggested functions for the formula and one or more suggested operands, which the computing apparatus presents in a user interface to the spreadsheet.
