Convert String to Json Array

Convert string to JSON array

Here you get JSONObject so change this line:

JSONArray jsonArray = new JSONArray(readlocationFeed);

with following:

JSONObject jsnobject = new JSONObject(readlocationFeed);

and after

JSONArray jsonArray = jsnobject.getJSONArray("locations");
for (int i = 0; i < jsonArray.length(); i++) {
    JSONObject explrObject = jsonArray.getJSONObject(i);
}

Convert array to JSON

Script for backward-compatibility:
https://github.com/douglascrockford/JSON-js/blob/master/json2.js

And call:

var myJsonString = JSON.stringify(yourArray);

Note: The JSON object is now part of most modern web browsers (IE 8 & above). See caniuse for full listing. Credit goes to: @Spudley for his comment below

SimpleJson: String to JSONArray

JSONParser parser = new JSONParser();
JSONArray array = (JSONArray)parser.parse("[{\"user_id\": 1}]");
System.out.println(((JSONObject)array.get(0)).get("user_id"));

You need to cast to a JSONArray as that is what the string contains.

String to JSON Array

You just need to run this through JSON.parse(), which is supported by almost all the JavaScript parsers:

console.log(JSON.parse(`[      [32.361346650846805,50.90932315437885],    [32.36743646734031,50.95189517586323],    [32.35467638118774,50.95876163094135],    [32.342494619322636,50.904516635824166],    [32.36279664436138,50.90039676277729],    [32.380194752587755,50.899023471761666],    [32.3648265962154,50.91481631844135],    [32.361346650846805,50.90932315437885]]`));

Converting from a String to JSONArray

Just add a square bracket to the start and end of the String, and then try to convert it to JSONArray.

"data": [
            {
               "prop": "[{\"Name\":\"StockoutTransferDate\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCTEXT\",\"value\":\"\"},\"Unit\":\"$\"},{\"Name\":\"LoadBearing\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCBOOLEAN\",\"value\":true},\"Unit\":\"$\"},{\"Name\":\"StockoutDeliveryDate\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCTEXT\",\"value\":\"\"},\"Unit\":\"$\"},{\"Name\":\"Status\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCTEXT\",\"value\":\"OnTransport\"},\"Unit\":\"$\"},{\"Name\":\"Tracked\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCTEXT\",\"value\":\"true\"},\"Unit\":\"$\"},{\"Name\":\"StockoutReturnDate\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCTEXT\",\"value\":\"\"},\"Unit\":\"$\"},{\"Name\":\"IsExternal\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCBOOLEAN\",\"value\":false},\"Unit\":\"$\"},{\"Name\":\"PlannedStockoutDeliveryDate\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCTEXT\",\"value\":\"10-03-2019\"},\"Unit\":\"$\"},{\"Name\":\"StockinReturnLocation\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCTEXT\",\"value\":\"\"},\"Unit\":\"$\"},{\"Name\":\"PlannedAssemblyDate\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCTEXT\",\"value\":\"27-04-2019\"},\"Unit\":\"$\"},{\"Name\":\"StockoutTransferLocation\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCTEXT\",\"value\":\"\"},\"Unit\":\"$\"},{\"Name\":\"StockinReturnDate\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCTEXT\",\"value\":\"\"},\"Unit\":\"$\"},{\"Name\":\"FabricatedLocation\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCTEXT\",\"value\":\"\"},\"Unit\":\"$\"},{\"Name\":\"StockinArrivalLocation\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCTEXT\",\"value\":\"\"},\"Unit\":\"$\"},{\"Name\":\"StockinTransferDate\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCTEXT\",\"value\":\"\"},\"Unit\":\"$\"},{\"Name\":\"Reference\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCIDENTIFIER\",\"value\":\"300 x 350\"},\"Unit\":\"$\"},{\"Name\":\"PlannedStockinArrivalDate\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCTEXT\",\"value\":\"11-03-2019\"},\"Unit\":\"$\"},{\"Name\":\"PlannedFabricatedDate\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCTEXT\",\"value\":\"01-03-2019\"},\"Unit\":\"$\"},{\"Name\":\"AssemblyDate\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCTEXT\",\"value\":\"\"},\"Unit\":\"$\"},{\"Name\":\"Slope\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCPLANEANGLEMEASURE\",\"value\":\"0\",\"orig_value\":\"0.\"},\"Unit\":\"$\"},{\"Name\":\"FabricatedDate\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCTEXT\",\"value\":\"\"},\"Unit\":\"$\"},{\"Name\":\"StockoutReturnLocation\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCTEXT\",\"value\":\"\"},\"Unit\":\"$\"},{\"Name\":\"Span\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCPOSITIVELENGTHMEASURE\",\"value\":\"4750\",\"orig_value\":\"4750.\"},\"Unit\":\"$\"},{\"Name\":\"StockinArrivalDate\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCTEXT\",\"value\":\"\"},\"Unit\":\"$\"},{\"Name\":\"StockoutDeliveryLocation\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCTEXT\",\"value\":\"\"},\"Unit\":\"$\"},{\"Name\":\"Status\",\"Description\":\"$\",\"NominalValue\":{\"type\":\"IFCTEXT\",\"value\":\"Assembled\"},\"Unit\":\"$\"}]"
            }
        ],

How to convert array of strings into JSON object?

use Object.fromEntries to construct an object out of your array elements after splitting them using : seperator:

let data = [
 "filter1:value",
 "filter2:value"
]

let result = Object.fromEntries(data.map(e => e.split(":")))

console.log(result)
