Abstract: An information processing device receives data that includes a plurality of items and an item value associated therewith, displays a matrix in which the items included in the data being received are arranged in either one of a row direction or a column direction, and one or more candidate items for an association destination with which a part or all of the items are associated, are arranged in the other direction; receives specification of a set of any item in the items and any item in the one or more candidate items for the association destination, by specification of a position on the matrix, using the processor; and stores a value of an item that is associated with the position having been specified among the items, in a storage unit, in association with an item that is associated with the position having been specified among the candidate items for the association destination.

Abstract: An information processing device receives a plurality of data files that include a plurality of items having a key item and an item value associated therewith and stores a value that is a value of an item having been associated with a same key item value and having been associated with a second association destination item in common, and that is included in a data file specified by a predetermined rule from two or more data files among the data files, in association with the second association destination item, when a key item that is associated with a first association destination item in common is included in the two or more data files and an item that is associated with the second association destination item is included in the two or more data files.
