Do this, but in perl. 

$ cat ~/fooble.clj
(require '[clojure.data.json :as j])

(def data
  [{"balance" 10.12 "cname" "Smart Parking"}
   {"balance" 10.22 "cname" "Smart Parking"}
   {"balance" 10.32 "cname" "Smart Parking"}
   {"balance" 20.12 "cname" "Highview Parking"}
   {"balance" 20.22 "cname" "Highview Parking"}
   {"balance" 20.32 "cname" "Highview Parking"}
   {"balance" 20.42 "cname" "Highview Parking"}
   {"balance" 30.12 "cname" "ParkingEye"}
   {"balance" 30.22 "cname" "ParkingEye"}])

(println
 (j/write-str
  (map (fn [[k v]] (merge {:cname k} v))
       (reduce (fn [acc {:strs [cname balance]}]
                 (-> acc
                     (assoc-in [cname :balance] (+ balance (get-in acc
+ [cname :balance] 0)))
                     (assoc-in [cname :total] (inc (get-in acc [cname 
+:total] 0))))) {} data))))


$ lein run -m clojure.main ~/fooble.clj
[{"cname":"Smart Parking","balance":30.66,"total":3},{"cname":"Highvie
+w Parking","balance":81.08000000000001,"total":4},{"cname":"ParkingEy
