A device includes a logic machine and a data-holding machine having instructions executable by the logic machine to receive a spreadsheet including a plurality of cells, apply an abstraction to the spreadsheet that defines one or more features of a cell set including one or more cells of the plurality of cells to form an abstracted representation of the spreadsheet, form, for the cell set, an input vector for a machine-learning prediction function from the abstracted representation of the spreadsheet, the machine-learning prediction function configured to output a prediction of one or more properties of the cell set based on the input vector, wherein the machine-learning prediction function is previously trained based on a plurality of previously-created spreadsheets, provide the input vector to the machine-learning prediction function; and output the prediction from the machine-learning prediction function.
