Hello, I have to do an application to handle 14 columns (date and 13 integer variables) and rows to cover day by day through 15 years. That is 14*365*15 cells.

I must do searches and comparisons between cells, and some mathematical calculations (those ones won't be through all cells, but just between some 10 or 20 selected cells).

The question is, should I use Access too to handle this information, or is Excel enough powerfull to work with that alone? I prefer working with Excel alone, but if it is needed, then the application will be made based on both.
