If there was some way to extend the number of columns then Microsoft would
NOT state that the limit is 256.
However, wait for Excel 12 1,048,576 rows and 165,384 columns

How to extend the Excel sheet from sheet 1 ( i.e. IV 256) to other
sheet(e.g.
sheet 2)? E.g. I want to input data 512 point into the column, but Excel
only
got 256 entry, how to extend the column to 512 in single sheet ?
