Convert column data into rows

I have a generic list with 10 columns. I am interested in converting the following four columns into two columns.
one called Product and the other column holding the Id number of the product.
and keep the rest of the six columns as is

ProductA 2345
ProductB 3456
ProductC 6789
productD 9876

I want to convert this into two columns
Product       ID
ProductA  2345
ProductB       3456
ProductC       6789
productD       9876

The end result in this case would result in four rows for every single row.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Please post an example of the data as it exists in your environment. You mentioned, "...keep the rest of the six columns as is." Where are the other six columns in your example?
