Determining Columns in a Range

One of the handy worksheet functions provided by Excel allows you to determine the number of columns in a range. This is accomplished through the use of the COLUMNS function. For instance, consider the following formula:

=COLUMNS(B2:D15)

The value returned is 3, since the range includes columns B, C, and D. You are not limited to address ranges (such as B2:D15), but can also used named ranges with the COLUMNS function.
