1. A method for exporting-importing the content of input cells from a source scalable template instance in a source multi-dimensional spreadsheet to a destination scalable template instance in a destination multi-dimensional spreadsheet, said method comprising the steps of: detecting a command for exporting-importing input cells from a source scalable template instance in a source spreadsheet to a destination scalable template instance in a destination spreadsheet; identifying a source scalable template associated with the source scalable template instance; identifying cells, defined as input cells in an element profile of the source scalable template; identifying a destination scalable template associated with the destination scalable template instance; identifying cells, defined as input cells in an element profile of the destination scalable template; and copying, cell per cell, the content of each input cell of the source scalable template instance in each input cell of the destination scalable template instance.
