You can not convert an excel file to sql server file.
But if you can figure out a structure where your rows will fit in, you can import the excel file with the
import wizard in
SQL Management Studio[

Be aware, that excel worksheets are not tables, they are sort of free-form. A relational table needs to have a structure, thus not all excel worksheets can be imported directly.
