The current limitations are 65536 rows and 256 columns.

These limitation are removed in Excel (office) 2007 ( 1 milion rows/64K
columns I think) which is currently in beta test. You can download the beta
from the Microsoft site.

I use Excel extensively for performance analysis and have a fairly complex
integration of different spreadsheets in different workbooks. I have found
that there is a physical limitation to the number of cells that I can use in
any one spreadsheet (seems to be about 67,010). Does anyone know how this
limitation can either be removed or increased?
