Need Help Exporting Excel To SQL 2005 Table

Scenario :
SQL table has 2 columns SQ1, SQ2
Excel sheet has three columns : EX1, EX2, EX3

SQ1 matches with EX2
SQ2 matches with EX3

I would like to insert the rows where EX1='X'. EX1 is the left most column in th Excel sheet.

Here's what I am trying. Could you suggest any changes/suggestions?

-- Link server logic
IF EXISTS (SELECT srv.name FROM sys.servers srv WHERE srv.server_id != 0 AND srv.name = N'Config_spreadsheet_load')EXEC master.dbo.sp_dropserver @server=N'Config_spreadsheet_load', @droplogins='droplogins'
GO

--This is the link logic to connect the spreadsheet to the database
sys.sp_addlinkedserver 'Config_spreadsheet_load',
Excel',
'Microsoft.Jet.OLEDB.4.0',
In : @ExcelfileName,
'excel 8.0;
IMEX=1;
GO

-- Insert Plan Codes, for the column (PLC_NEW_COL) marked as ‘X’
insert into Plan_code (SQ1,
SQ2)
-- **** How can I have the logic for checking EX1='X'
where PLC_NEW_COL like ‘X’
-- Once the data has been created, clean-up
