FwBoxLiteJson

Very tiny json parser. It can't pasrse full tree. It can only search for the key and get it's value.

Arduino example:

#include "FwBoxLiteJson.h"

void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  Serial.println();
}

void loop() {
  // put your main code here, to run repeatedly:
  FwBoxLiteJson lj;
  
  String str_json = "{\"Name\":\"John\",\"Age\":18,\"Phone\":\"0900111222\",\"TEST\":[\"AA\",\"BB\",\"CC\"]}";

  Serial.println(str_json);

  int temp_i = 0xfe;
  if (lj.getInt(&str_json, "Age", &temp_i) == 0) { // success
    Serial.print("Age = ");
    Serial.println(temp_i);
  }

  String temp = "";
  if (lj.getString(&str_json, "Phone", &temp) == 0) { // success
    Serial.print("Phone = ");
    Serial.println(temp);
  }

  String temp_arr[5];
  temp_i = 5;
  if (lj.getArrayString(&str_json, "TEST", temp_arr, &temp_i) == 0) { // success
    Serial.print("Array Count = ");
    Serial.println(temp_i);
    for(int ii = 0; ii < temp_i; ii++) {
      Serial.print("TEST[");
      Serial.print(ii);
      Serial.print("] = ");
      Serial.println(temp_arr[ii]);
    }
  }

  Serial.println();

  delay(10 * 1000);
}

Output:

Original json string = {"Name":"John","Age":18,"Phone":"0900111222","TEST":["AA","BB","CC"]}
Age = 18
Phone = 0900111222
Array Count = 3
TEST[0] = AA
TEST[1] = BB
TEST[2] = CC
