How to store nested JSON object into Firebase Database?

Question

How to store string containing nested Json object in a proper tree format

sample string:

152#233.69#-191.7#133.69#-199.769#AP#4#"{""pot"":4}"#TP#"{""Dp"":12345}" 1581#233.69#-191.7#133.69#-199.769#4#"{""pt"":4,""oil"":{""1"":""HP""}}"#UP#"{""Dp"":67890}" 16849#343.69#-291.8#133.69#-389.769#AMULL#4#"{""sport"":4,""oi"":{""1"":""LT""}}"#null#"{""Dis"":67990}"

each value is separated by # and the values maybe string representation of nested JSON objects

My code:

var myNewLine = arrayOne[i].split('#');
for (var j = 0; j < noOfCol; j++) {
        var temp;
        var headerText = header[j].substring(0, header[j].length);
        valueText = myNewLine[j].substring(0, myNewLine[j].length);
        obj[headerText] = valueText;
     }
    jArray.push(obj);
}
jsonObject = JSON.parse(JSON.stringify(jArray));
 return jsonObject;

JSON.parse(JSON.stringify(jArray)): That's an expensive noop... — Andreas

Get your data in JSON format and use .update or .set to save it to the Realtime Database. You can use the function below

function update(node,key,value){
    var ref = firebase.database().ref('/');
    var obj = {};
    obj[key] = value;
    ref.child(node).update(obj)
    .then(function() {
        console.log('Update Ran Successfully');
    });       
}

For of the string you are passing to the JSON.parse is not correct. Replace two double quotes by single double quote.
