Excel Data Pivot/unpivot To Sql Server 2005 Table

The following is a SAMPLE data from an excel spreadsheet. This SAMPLE data has many other fields as date. Here I have only used two date columns i.e. 28 Dec 2006 and 29 Dec 2006
This data needs to be exported into sql server 2005 table which has the fields below where I have placed the data into a table.
How can this be done please?

3 Sovereign RUSSIA 10 114.33 104.63
4 Sovereign RUSSIA 18 115.50 145.50
