Escape the symbols in JSON object

Question

I have this JSON object

{'zone1': [{'detected_people': {'coordinates': [[21, 0], [16, 4], [23, 4], [21, 6], [16, 21]]}, 'gridOrigin': [28.5, 20.6], 'gridScale': 0.5, 'gridSizeX': 50, 'gridSizeY': 50, 'stamp': '2020-08-28 21:06:48', 'zoneID': 'shop1'}]}

I can't submit to webservice database. My server side suggested me to escape the symbols.

I am creating JSON object using jsoncpp as follows.

struct JSON_PEOPLE{
   //Json::Value root;
   Json::Value zone_1;   
   Json::Value zone_2;
   Json::Value zone1;   
   Json::Value zone2;
   Json::Value coord;
   Json::Value gridOrigin;
   
   JSON_PEOPLE(){
     zone1["zoneID"] = "shop1";
     zone1["stamp"] = "##########";
     zone1["gridSizeX"]=50;
     zone1["gridSizeY"]=50;
     zone1["gridScale"]=0.5;
     zone1["gridOrigin"].append(28.5);
     zone1["gridOrigin"].append(20.6);
     

     zone2["zoneID"] = "shop2";
     zone2["stamp"] = "##############";
     zone2["gridSizeX"]=50;
     zone2["gridSizeY"]=50;
     zone2["gridScale"]=0.5;
     zone2["gridOrigin"].append(35.5);
     zone2["gridOrigin"].append(40.6);
   }
}

How can I escape symbols?

This is not valid JSON. JSON uses double quotes for all strings and property names. How is it created? — Felix Kling, Aug 28 '20 at 13:18
Created JSON using JSONCPP and my C code has interface to Python. Json string was sent to Python and I used json.loads(info) to convert Json string to JSON object. That json.loads changed all double quotes to single quotes. — batuman, Aug 28 '20 at 14:17

I have correct JSON string.

{
    "zone1" : 
    [
        {
            "detected_people" : 
            {
                "coordinates" : 
                [
                    [
                        22,
                        3
                    ],
                    [
                        21,
                        6
                    ],
                    [
                        16,
                        21
                    ]
                ]
            },
            "gridOrigin" : 
            [
                28.5,
                20.600000000000001
            ],
            "gridScale" : 0.5,
            "gridSizeX" : 50,
            "gridSizeY" : 50,
            "stamp" : "2020-08-28 22:23:05",
            "zoneID" : "shop1"
        }
    ]
}

When converted to JSON object, I have to do json_obj = json.dumps(json.loads(info)). So I have correct double quotes.
