Facing issue with Exporter while exporting with JSONObject on page getting unwanted format like 

Getting :

 "options" : {
                        "id-option-1" : {
                          "altText" : {
                            "chars" : "default:asset:description",
                            "string" : "default:asset:description",
                            "valueType" : "STRING"
                          },
                          "description" : {
                            "chars" : "\u003Cp\u003ESample Descritption\u003C/p\u003E",
                            "string" : "\u003Cp\u003ESample Descritption\u003C/p\u003E",
                            "valueType" : "STRING"
                          }
                        },
                        "id-option-2" : {

                            "string" : "default:asset:description",
                            "valueType" : "STRING"
                          },

                            "string" : "\u003Cp\u003Esample description 2\u003C/p\u003E",
                            "valueType" : "STRING"
                          }
                        },

required format:

options: {
'id-option-1': {
description: 'Some description 2',
buttonText: 'This is the option 1 text',
},
'id-option-2': {
description: 'Some description 2',
buttonText: 'The is the option 2 text',
},
'id-option-3': {
description: 'Some description 3',
buttonText: 'This is the option 3 text',

JAVA method in Exporter:

public JsonObject getOptions() {
JsonObjectBuilder jsonkey = Json.createObjectBuilder();

int i = 1;
for (Resource resource: content) {

TreeModel resourceValues = resource.adaptTo(TreeModel.class);
JsonObjectBuilder keynewsArticleJSON = Json.createObjectBuilder();

//keynewsArticleJSON.add("fileReference", (String) resourceValues.getFileReference());

keynewsArticleJSON.add("altText", (String) resourceValues.getAltText());

keynewsArticleJSON.add("description", (String) resourceValues.getDescription().toString());

log.info("filesResference:::::::::::" + resourceValues.getFileReference());

jsonkey.add("id-option-" + i, keynewsArticleJSON.build());
i++;
}

log.info("jsonSsdtring::::::::::::::" + jsonkey.build());

String jsonString = jsonkey.build().toString();
JsonReader jsonReader = Json.createReader(new StringReader(jsonString));

JsonObject object = jsonReader.readObject();

return object;
}
