From Excel Convert into sqlserver database

I think first you need to export excel to datatable, please see below code:

Workbook workbook = new Workbook();
workbook.LoadFromFile("DataTableSample.xls");
Worksheet sheet = workbook.Worksheets[0];
DataTable dataTable = sheet.ExportDataTable();


then connect your datatble to sql sever. but you need a c# excel component to perform above
code.of course,if you also need to import datatable from database to excel, this tool also can help you.
