{
    string filename = "DataTableSample.xlsx";
    int sheetId = 0;

    // Load workbook from local excel file
    Workbook workbook = new Workbook(filename);

    // Export data table from worksheet
    DataTable dt = workbook.ConvertSheetToDataTable(sheetId);

    // Save data to sql database
    insertTableToSqlServer(dt);
}

private static void insertTableToSqlServer(DataTable dt)
{
    string connString = @"Data Source=.;Initial Catalog=database name;Integrated Security=True";
    string query = @"INSERT INTO tableName (paramColum) VALUES (@paramName)";

    using (SqlConnection sqlConn = new SqlConnection(connString))
    {
        using (SqlCommand sqlComm = new SqlCommand(query, sqlConn))
        {
            sqlComm.Parameters.Add("@paramName", SqlDbType.Text);
            sqlConn.Open();

            foreach (DataRow dr in dt.Rows)
            {
                string paramSource = dr[0].ToString();
                sqlComm.Parameters["@paramName"].Value = paramSource;
                //...
