I have one XML which i need to convert to JSON when in XML we have more than one element its creating proper jsonArray but when single element not creating the array can any one please help me how we can get array in case of single element

String TEST_XML_STRING = "<Items><Item><Name>Stack</Name><Name>OverFlow</Name></Item></Items>";
// output - {"Items":{"Item":{"Name":["Stack","OverFlow"]}}}


String TEST_XML_STRING = "<Items><Item><Name>Stack</Name></Item></Items>";
// output - {"Items":{"Item":{"Name":"Stack"}}}

but it should be {"Items":{"Item":[{"Name":"Stack"}]}}

I'm late on this... but, using org.json:

public static void forceToJSONArray(JSONObject xmlJSONObj, String obj) throws org.json.JSONException 
    // where "JSONObject xmlJSONObj" is my JSONObject obtained by passing the XML throug the metod toJSONObject 
    // and where "String obj" is the name of the JSONObject I want to force to JSONArray
    Object myObj = xmlJSONObj.opt(obj);
    if (myObj == null)
        // if my obj doesn't exist inside my xmlJSONObj i create it empty
        JSONArray jsonArray = new JSONArray();
        xmlJSONObj.put(obj, jsonArray);
    else if ( myObj instanceof JSONObject ) 
        // if exist but is a JSONObject, I force it to JSONArray
        JSONObject myJSONObj = (JSONObject)myObj;
        JSONArray jsonArray = new JSONArray();
        xmlJSONObj.put(obj, jsonArray);
     else if ( myObj instanceof String || myObj instanceof Integer ) 
        // if exist but is a primitive entry (like in your case), I force it to a "primitive" JSONArray
        JSONArray jsonArray = new JSONArray();
        xmlJSONObj.put(obj, jsonArray);

Hope this could help ;)

How to convert XML to JSON array in Java?, We can convert XML to JSON array using org. json. XML class, this provides a static method, XML. toJSONObject() to convert XML to JSON array.

Having issue while convertnig xml with single element to json array , I am getting But when i have only one entry in json array it don't. I am currently using Newtonsoft to convert some xml to json to return from a RestExtension. Convert XML to Json Array when only one object. Force JSON.NET to

There doesn't seem to be out of the box way of doing that. If the json is processed in the code later on you could check whether it's JSONObject or JSONArray.

When it's JSONObject you will have to replace it with JSONArray with the same data.

Test if it is JSONObject or JSONArray

XML to json Array Issue · Issue #235 · stleary/JSON-java · GitHub, I need to parse a specific XML element of xml content, that has only one occurency, to a JSON Array object, using XML.toJSONObject(xml). This sample reads the json:Array="true" attribute in the XML and places its value in an array when converting the XML to JSON.

If you are using Java 8 or later, you should check out my open source library: unXml. unXml basically maps from Xpaths to Json-attributes.

It's available on Maven Central.


import com.fasterxml.jackson.databind.node.ObjectNode;
import com.nerdforge.unxml.factory.ParsingFactory;
import com.nerdforge.unxml.parsers.Parser;
import org.w3c.dom.Document;

public class Parser {
  public ObjectNode parseXml(String xml){
    Parsing parsing = ParsingFactory.getInstance().create();
    Document document = parsing.xml().document(xml);

    Parser<ObjectNode> parser = parsing.obj("/Items/Item")
        .attribute("name", "Name")

    ObjectNode result = parser.apply(document);
    return result;

It will return a Jackson ObjectNode, with the following json:


You can also create a parser that will return nested ObjectNodes or ArrayNodes to whatever JSON structure you desire.

Convert XML to JSON and force array, This sample reads the json:Array="true" attribute in the XML and places its value in an array when converting the XML to JSON. In this tutorial you will learn how to convert json to xml or xml to json in java.

I use these two methods, but you will have to identify which fields you want to wrap in a array. With javax.json.*:

private static JsonObject wrapFieldInArray(JsonObject object, String fieldKey) {
    JsonValue fieldValue = object.get(fieldKey);
    if(fieldValue instanceof JsonObject){
        JsonObjectBuilder builder = Json.createObjectBuilder(object);
        builder.add(fieldKey, wrapObjectInArray((JsonObject) fieldValue));
        object =;
    return object;

public static JsonArray wrapObjectInArray(JsonObject obj){
    JsonArrayBuilder builder = Json.createArrayBuilder();

And with org.json:

private static JSONObject wrapFieldInArray(JSONObject object, String fieldKey) {
    Object fieldValueObj = object.get(fieldKey);
    if(fieldValueObj instanceof JSONObject){
        JSONObject fieldValue = (JSONObject) fieldValueObj;
        object.put(fieldKey, wrapObjectInArray(fieldValue));
    return object;

public static JSONArray wrapObjectInArray(JSONObject obj){
    return new JSONArray().put(new JSONObject(obj.toString()));
