Flattening JSON but keep original properties - json

Question

I am trying to flatten properties (i.e. objects, array) of a JSON object, but keep the original properties the same, and turn non-scalar properties into strings.
(I'm doing this because when I use the flat npm package, arrays/objects are flattened, but object keys are surrounded by '' , like in 'task_status.0.data' and do not get stored into AzureTables). If there is a way to fix that and de-string that, it would be an ok solution as well...)
Here's an example you could run on jsfiddle.net
var obj1 = {
"studentId": "abc",
"task_status": [
{
"status":"Current",
"date":516760078
},
{
"status":"Late",
"date":1516414446
}
],
"student_plan": "n"
}
FlattenJson = function(obj){
keys = Object.keys(obj);
var newObj = {};
for(var i=0; i<keys.length; i++){
var theType = typeof(obj[keys[i]]);
console.log(theType);
if(theType === 'array' || theType === 'object'){
console.log(JSON.stringify(obj[keys[i]]));
newObj[keys[i]] = "\"" + JSON.stringify(obj[keys[i]]) + "\"";
}
newObj[keys[i]] = obj[keys[i]];
}
return newObj;
}
var newObj1 = FlattenJson(obj1);
console.log(newObj1, obj1);
However, the newobj1 contains the same original array, instead of a string. How would I fix this?

UPDATED: Thanks to this you have a solution.
var obj1 = {
"studentId": "abc",
"task_status": [
{
"status":"Current",
"date":516760078
},
{
"status":"Late",
"date":1516414446
}
],
"student_plan": "n"
}
function customToString (obj) {
var str = '{';
for (var prop in obj) {
if (obj.hasOwnProperty(prop)) {
str += prop + ':"' + obj[prop] + '",';
}
}
return str.replace(/.$/,'') + '}';
}
var flattenObject = function(ob) {
var toReturn = {};
for (var i in ob) {
if (!ob.hasOwnProperty(i)) continue;
if ((typeof ob[i]) == 'object') {
var flatObject = flattenObject(ob[i]);
for (var x in flatObject) {
if (!flatObject.hasOwnProperty(x)) continue;
toReturn[i + '.' + x] = flatObject[x];
}
} else {
toReturn[i] = ob[i];
}
}
return toReturn;
};
var newObj1 = flattenObject(obj1);
console.log(newObj1, obj1);
document.write(customToString(newObj1));
