To provide a method and a system for persistently self-replicating a plurality of ranges of cells through a copy-paste operation in a multiple dimensional spreadsheet.

This method includes a step for defining a set of ranges of cells where each range of cells has the same size and a step for automatically performing a self-replication operation each time the contents of the ranges of cells belonging to the set are changed. A spreadsheet user decides to perform preparation, elimination and name change of a persistent self-replication set(PSRS), addition of a persistent self-replication range(PSRR) to the PSRS or suppression of the PSRR from the PSRS, and data necessary to this operation is recorded by using a common repository called a 'persistent self-replication table'.
