1. A computer-implemented method for self-replicating ranges of cells in a spreadsheet, the method comprising executing on a central processor the steps of: presenting, within a graphical user interface, a plurality of unique set names that are each assigned to one each of a plurality of different sets of ranges of cells of a spreadsheet, wherein each of the unique set names are assigned to at least one of the ranges, and each of the ranges of cells comprise a plurality of different cells of the spreadsheet; in response to a selection of one of the presented unique set names via an input to the graphical user interface, listing at least one range of the plurality of the ranges that is assigned to the selected unique set name; and in response to an update of one of the cells of the listed at least one range of the plurality of the ranges that is assigned to the selected unique set name via the graphical user interface, automatically entering the update into all other ones of the cells of the ranges that are assigned to the set of the selected unique set name by: establishing a top record within a self replication table containing an address field of the unique set name, a pattern of the cells of the ranges assigned to the selected unique set name, and set and range indices of the cells of the ranges assigned to the selected unique set name; setting the top record of the self replication table as the current record; and updating the all other ones of the cells of the ranges assigned to the selected unique set name set by retrieving the address field of the unique set name from the top record of the self replication table set as the current record and pasting the update entered by the user into the one of the cells into the all other ones of the cells of the ranges assigned to the selected unique set name that are pointed to by the retrieved address field.
