2          eslam

so can any one help me to export data to excel file without change or overwrite header ?

I am not sure, but this line may be the source of your problem:

(‘dbo.students’,‘TRY_CONVERT(VARCHAR(MAX),StudentId) AS [StudentId], Name’)

You can try replacing ‘Name’ with StudentName or [StudentName].
