Organizing a CSV file with JSON datat - java

I am trying to populate a CSV file with json data, but I need to organize everything a certain way. I need the json keys to be headers and the associated values be the data under it, but the way the json is set up I can populate names in one, but the info in another block labeled "items" needs to be split up among multiple cells with keys being the header and the values populating the table. I do not know how to split up individual components of a json block into its own cells.
So CSV should be set up like:
headers: name item1 item2 item3
data cells: [first last] [value1] [value2] [value3]
JSON looks like this:
{
"info":[
{
"name":{
"first" : -----
"last":-----
},
"item": [
{
"item1" : "value1"
"item2" : "value2"
"item3" : "value3"
}
]
}
I have used the Apache commons FileUtils.writeStringToFile, but that writes all the "items" keys and values in one cell, I need 1 item to 1 cell. The name is fine because the components can go in one cell, I just need to split up the items.
The result so far is Name is one header and the cell under that header has first and last name, the second header is Items and lists all keys and values in that json block in that one cell.
I expect the items keys to be the header and the values under those and split up.
Any help or direction would be greatly appreciated.
UPDATE: To clarify I am pulling the JSON data from a URL so the way it is written is the way it is. I can not change it.

public static void main(String[] args) throws IOException {
JSONObject jo = (JSONObject) JSONObject.parse("{\"info\":[{\"name\":{\"first\" : \"-----\",\"last\":\"-----\"},\"item\": [{\"item1\" : \"value1\",\"item2\" : \"value2\",\"item3\" : \"value3\"}]}]}");
String line1 = "headers:\tname\titem1\titem2\titem3\n";
String line2 = "data cells:";
JSONArray info = jo.getJSONArray("info");
JSONObject info1 = info.getJSONObject(0);
JSONObject name = info1.getJSONObject("name");
String nameKeys = name.keySet().toString();
JSONArray item = info1.getJSONArray("item");
JSONObject firstItem = item.getJSONObject(0);
String item1Value = firstItem.getString("item1");
String item2Value = firstItem.getString("item2");
String item3Value = firstItem.getString("item3");
line2 = line2 + "\t" +nameKeys + "\t"+ item1Value +"\t"+item2Value+"\t"+item3Value+"\n";
BufferedWriter bw = new BufferedWriter(new FileWriter("C:\\Users\\user\\Desktop\\test.csv"));
bw.write(line1);
bw.write(line2);
bw.close();
}
just look like this ,get the value and write them to the csv file.
Another way you can use regex like (?<=item\d"\s:\s").*?(?=") to match the "value1","value2","value3" and regex item\d mathches "item1","item2","item3" to cut out the json string to get the value.

public class JsonToCsv {
public static void main(String args[]) throws JSONException, IOException
{
List<JSONObject> infoList=new ArrayList<JSONObject>();
JSONObject info=new JSONObject();
JSONObject name=new JSONObject();
name.put("first", "John");
name.put("last","Doe");
info.put("name",name );
List<JSONObject> itemList=new ArrayList<JSONObject>();
JSONObject item1=new JSONObject();
JSONObject item2=new JSONObject();
item1.put("item1", "val1");
itemList.add(item1);
item2.put("item2", "val2");
itemList.add(item2);
info.put("item", itemList);
infoList.add(info);
System.out.println(infoList);
convertJsonToCsv(infoList);
}
public static void convertJsonToCsv(List<JSONObject> infoList) throws IOException, JSONException {
FileWriter csvWriter = new FileWriter("InfoFile.csv");
List<String> header= new ArrayList<String>();
List<String> values = new ArrayList<String>();
for(int i=0;i<infoList.size();i++) {
JSONObject info_obj=infoList.get(i);
Iterator<String> info_keys=info_obj.keys();
while(info_keys.hasNext()) {
String key = info_keys.next();
if (info_obj.get(key) instanceof JSONObject) {
JSONObject obj=info_obj.getJSONObject(key);
Iterator<String> obj_keys=obj.keys();
while(obj_keys.hasNext()) {
String k=obj_keys.next();
if(i==0)
header.add(k);
values.add(obj.getString(k));
}
}
if (info_obj.get(key) instanceof JSONArray) {
JSONArray item_array=info_obj.getJSONArray(key);
for(int j=0;j<item_array.length();j++) {
JSONObject item=item_array.getJSONObject(j);
Iterator<String> item_keys=item.keys();
while(item_keys.hasNext()) {
String k=item_keys.next();
if(i==0)
header.add(k);
values.add(item.getString(k));
}
}
}
}
}
for(String head : header) {
csvWriter.append(head);
csvWriter.append(",");
}
csvWriter.append("\n");
for(int m=0;m<values.size();m++) {
csvWriter.append(values.get(m));
if((m+1)%(header.size())==0) {
csvWriter.append("\n");
}

csvWriter.append(",");

How to export a nested JSONArray to CSV?

I have a JSONArray which contains multiple JSONObjects
[
{
"record":[
{
"timeStamp":"2018-10-11T05:36:51+00:00",
"code":200,
"text":"OK"

How can I parse this JSONArray and export it as a CSV File.
This is what I have tried so far
File file=new File("/home/administrator/Desktop/test.csv");
String csv = jsonArray;
FileUtils.writeStringToFile(file, csv);
System.out.println("CSV created.");
My desired output is
timeStamp,code,text,hostname,address,type,priority,ttl,hostname,address,type,priority,ttl
2018-10-11T05:36:51+00:00,200,OK,qwe,192.168.1.1,A,0,300,www,test.com,CNAME,0,3600
2018-10-11T05:36:52+00:00,200,OK,rty,192.168.1.2,A,0,300,*,test,CNAME,0,3600
Is it possible to have an output like this given the JSONArray above?
Sorry for the late respond was bashing my keyboard for the past 30 minutes but I finally got it done, here is the code.
public static String getCSVData() throws IOException, JSONException {
Path jsonFile = Paths.get("json");
String json = new String(Files.readAllBytes(jsonFile), StandardCharsets.UTF_8);
JSONArray jsonArray = new JSONArray(json.trim());
List<List<String>> jsonArrays = new ArrayList<>();
for (int i = 0; i < jsonArray.length(); i++) {
List<String> jsonObjects = new ArrayList<>();
JSONArray record = jsonArray.getJSONObject(i).getJSONArray("record");
for (int i2 = 0; i2 < record.length(); i2++) {
JSONObject jsonObject = record.getJSONObject(i2);
if (i2 == 0) {
jsonObjects.add(jsonObject.get("timeStamp").toString());
jsonObjects.add(jsonObject.get("code").toString());
jsonObjects.add(jsonObject.get("text").toString());
} else {
jsonObjects.add(jsonObject.get("hostname").toString());
jsonObjects.add(jsonObject.get("address").toString());
jsonObjects.add(jsonObject.get("type").toString());
jsonObjects.add(jsonObject.get("priority").toString());
jsonObjects.add(jsonObject.get("ttl").toString());
}
}
jsonArrays.add(jsonObjects);
}
StringBuilder stringBuilder = new StringBuilder("timeStamp,code,text,hostname,address,type,priority,ttl,hostname,address,type,priority,ttl\n");
for(List<String> arrays : jsonArrays){
stringBuilder.append(StringUtils.join(arrays, ",")).append("\n");
}
return stringBuilder.toString().trim();
}
To explain the code first I looped over the first Array and then get the jsonObject of the first JSONArray and then get the jsonArray named "record" from the JsonObject I have gotten by looping over the first JSONArray and then loop over record and get all the items and save them into an ArrayList. and join them via StringUtils which is provided by JDK.
if you want to write it to file use this
Files.write(Paths.get("YOUR CSV FILE"), getCSVData().getBytes(StandardCharsets.UTF_8));
all the code I used are provided by JDK and org.json.
after we print out getCSVDate(); the output is:
timeStamp,code,text,hostname,address,type,priority,ttl,hostname,address,type,priority,ttl
2018-10-11T05:36:51+00:00,200,OK,qwe,192.168.1.1,A,0,3600,www,test.com,CNAME,0,3600
2018-10-11T05:36:52+00:00,200,OK,rty,192.168.1.2,A,0,300,*,test,CNAME,0,3600

Adding json array in a json object in java

I am struggling to fit in a jsonArray inside a json object (through java code).. please help me out.
My Input JsonObject is :
{
"products":{
"productId":"712161780324",
"imageURL":"http:example.com/imageResource.jpg",
"internalItemCode":"N08792 8W"
}
}
I will have to read "imageURL" property from this JSONObject and append its variants to the same json object (image variants will be in SortedSet data structure).
Sample O/P 1 :
{
"products":{
"productId":"712161780324",
"imageURL":"http:example.com/imageResource.jpg",
"internalItemCode":"N08792 8W",
"variants":[
"http:example.com/imageResource_variant1.jpg",
"http:example.com/imageResource_variant2.jpg"
]
}
}
Sample O/P 2 :
{
"products":{
"productId":"712161780324",
"imageURL":"http:example.com/imageResource.jpg",
"internalItemCode":"N08792 8W",
"variants":[
{
"url" : "http:example.com/imageResource_variant1.jpg"
},
{
"url" : "http:example.com/imageResource_variant2.jpg"
}
]
}
}
The logic i tried to get sample output 2 is some what like below,
// productDetail is the give input JSONObject
JSONObject product = productDetail.optJSONObject("products");
SortedSet<String> imageUrls = new TreeSet<>();
imageUrls.add("http:example.com/imageResource_variant1.jpg");
imageUrls.add("http:example.com/imageResource_variant2.jpg");
Iterator<String> itr = imageUrls.iterator();
JSONArray imageUrlsArray = new JSONArray();
while (itr.hasNext()) {
JSONObject imageUrlObj = new JSONObject();
imageUrlObj.put("url", itr.next());
imageUrlsArray.put(imageUrlObj);
}
product.append("variants", imageUrlsArray);
When i tried to print the productDetail JSON object after executing above logic
System.out.println(productDetail.toString());
I observed the following output :
{
"products":{
"productId":"712161780324",
"imageURL":"http:example.com/imageResource.jpg",
"internalItemCode":"N08792 8W",
"variants":[
[
{
"url" : "http:example.com/imageResource_variant1.jpg"
},
{
"url" : "http:example.com/imageResource_variant2.jpg"
}
]
]
}
}
If you notice, It's coming up like Array of arrays (extra [ ] for "variants"),
Please help me in understanding Where my logic is going wrong.
And also, Please help me getting the First sample out put.
Appreciate quick response..
Thanks,
Rohit.
First sample can be archivable as simple as this:
JSONObject product = productDetail.optJSONObject("products");
JSONArray imageUrlsArray = new JSONArray();
imageUrlsArray.put(0, "http:example.com/imageResource_variant1.jpg");
imageUrlsArray.put(1, "http:example.com/imageResource_variant2.jpg");
product.append("variants", imageUrlsArray);
Try using put instead of append:
JSONObject product = productDetail.optJSONObject("products");
SortedSet<String> imageUrls = new TreeSet<>();
imageUrls.add("http:example.com/imageResource_variant1.jpg");
imageUrls.add("http:example.com/imageResource_variant2.jpg");
Iterator<String> itr = imageUrls.iterator();
JSONArray imageUrlsArray = new JSONArray();
while (itr.hasNext()) {
JSONObject imageUrlObj = new JSONObject();
imageUrlObj.put("url", itr.next());
imageUrlsArray.put(imageUrlObj);
}
-product.append("variants", imageUrlsArray);
+product.put("variants", imageUrlsArray);
From the docs:
Append values to the array under a key. If the key does not exist in the JSONObject, then the key is put in the JSONObject with its value being a JSONArray containing the value parameter. If the key was already associated with a JSONArray, then the value parameter is appended to it.

How to parse a JSON string using ggson to get field values

I have a sample JSON as below. I need to get the individual fields like ASIdentifer and ExternalIdentifer. I have stored this JSON data in a string.
Using GoogleJson as the module(ggson)
JSON data:
{
"DeviceCommon": {
"ASIdentifier": "123",
"DatadeliveyMechanism": "notify",
"MobileOriginatorCallbackReference": {
"url": "http://application.example.com/inbound/notifications/modatanotification/"
},
"AccessiblityCallbackReference": {
"url": "http://application.example.com/inbound/notifications/accessibilitystatusnotification"
}
},
"DeviceList": [{
"ExternalIdentifer": "123456#mydomain.com",
"msisdn": "123456",
"senderName": "Device1",
"MobileOriginatorCallbackReference": {
"notifyURL": "http://application.example.com/inbound/notifications/modatanotification/"
},
"ConfigurationResultCallbackReference": {
"notifyURL": "http://application.example.com/inbound/notifications/configurationResult"
},
"ASreferenceID": "AS000001",
"NIDDduration": "1d"
}]
}
I created the POJO classes and parsed the data using below code
data = new Gson().fromJson(new FileReader("/home/raj/apache-tomcat-8.0.3/webapps/file.json"), Data.class);
System.out.println(data);
Output:
Data{
deviceCommon=DeviceCommon{
asIdentifier='123'
datadeliveyMechanism='notify'
mobileOriginatorCallbackReference=http://application.example.com/inbound/notifications/modatanotification/
accessiblityCallbackReference=http://application.example.com/inbound/notifications/accessibilitystatusnotification
}
deviceList=[DeviceListEntry{
externalIdentifer='123456#mydomain.com'
msisdn='123456'
senderName='Device1'
mobileOriginatorCallbackReference=http://application.example.com/inbound/notifications/modatanotification/
configurationResultCallbackReference=http://application.example.com/inbound/notifications/configurationResult
asReferenceID='AS000001'
nidDduration='1d'
}]
}
String jsonInString = gson.toJson(data);
System.out.println("String is"+ jsonInString);
Output:
String is{"DeviceCommon":{"ASIdentifier":"123","DatadeliveyMechanism":"notify","MobileOriginatorCallbackReference":{"url":"http://application.example.com/inbound/notifications/modatanotification/"},"AccessiblityCallbackReference":{"url":"http://application.example.com/inbound/notifications/accessibilitystatusnotification"}},"DeviceList":[{"ExternalIdentifer":"123456#mydomain.com","msisdn":"123456","senderName":"Device1","MobileOriginatorCallbackReference":{"notifyURL":"http://application.example.com/inbound/notifications/modatanotification/"},"ConfigurationResultCallbackReference":{"notifyURL":"http://application.example.com/inbound/notifications/configurationResult"},"ASreferenceID":"AS000001","NIDDduration":"1d"}]}
I need to parse this JSON string to get individual fields like ExternalIdentifier and ASIdentifier.
I tried something like this but it is not working.
JsonObject jobj = new Gson().fromJson(jsonInString, JsonObject.class);
String result = jobj.get("ASIdentifier").toString();
System.out.println("value is"+ result);
Note: ExternalIdentifier is within the array, so I need to loop through the array to find it.
Can you please tell me what I'm doing wrong?
Possible solution:
String result = jobj.get("DeviceCommon").getAsJsonObject().get("ASIdentifier").getAsString();
System.out.println("ASIdentifier: "+ result);
JsonArray jsonArray = jobj.get("DeviceList").getAsJsonArray();
for (JsonElement device : jsonArray ) {
result = device.getAsJsonObject().get("ExternalIdentifer").getAsString();
System.out.println("ExternalIdentifer: "+ result);
}
Output:
ASIdentifier: 123
ExternalIdentifer: 123456#mydomain.com
public static void printJson(JsonElement jsonElement,String key) {
// Check whether jsonElement is JsonObject or not
if (jsonElement.isJsonObject()) {
Set<Entry<String, JsonElement>> ens = ((JsonObject) jsonElement).entrySet();
if (ens != null) {
// Iterate JSON Elements with Key values
for (Entry<String, JsonElement> en : ens) {
// System.out.println("##key is"+en.getKey() + " : ");
printJson(en.getValue(), en.getKey());
// System.out.println(en.getValue().getAsString());
// System.out.println(jsonElement.getAsString());
}
}
}
// Check whether jsonElement is Primitive or not
else if (jsonElement.isJsonPrimitive()) {
// print value as String
System.out.println("###key is"+key);
System.out.println("### value is"+jsonElement.getAsString());
}
else if (jsonElement.isJsonArray()) {
JsonArray jarr = jsonElement.getAsJsonArray();
// Iterate JSON Array to JSON Elements
System.out.println("\n###Array size is"+ jarr.size());
for (JsonElement je : jarr) {
printJson(je,key);
}
}
}

How to get dynamically changed Key's value in Json String using java

I'm trying to parse Json string using java, I have stuck up with some scenario.
See below is my JSON String:
"NetworkSettings": {
"Ports": {
"8080/tcp": [ // It will change dynamically like ("8125/udp" and "8080/udp" etc....)
{
"HostIp": "0.0.0.0",
"HostPort": "8080"
}
]
}
}
I try to parse the above json string by using the following code:
JsonObject NetworkSettings_obj=(JsonObject)obj.get("NetworkSettings");
if(NetworkSettings_obj.has("Ports"))
{
JsonObject ntw_Ports_obj=(JsonObject)NetworkSettings_obj.get("Ports");
if(ntw_Ports_obj.has("8080/tcp"))
{
JsonArray arr_ntwtcp=(JsonArray)ntw_Ports_obj.get("8080/tcp");
JsonObject ntwtcp_obj=arr_ntwtcp.get(0).getAsJsonObject();
if(ntwtcp_obj.has("HostIp"))
{
ntw_HostIp=ntwtcp_obj.get("HostIp").toString();
System.out.println("Network HostIp = "+ntw_HostIp);
}
if(ntwtcp_obj.has("HostPort"))
{
ntw_HostPort=ntwtcp_obj.get("HostPort").toString();
System.out.println("Network HostPort = "+ntw_HostPort);
}
}
else
{
ntw_HostIp="NA";
ntw_HostPort="NA";
}
}
else
{
ntw_HostIp="NA";
ntw_HostPort="NA";
}
In my code I have used this code
JsonArray arr_ntwtcp=(JsonArray)ntw_Ports_obj.get("8080/tcp");
to get the value of "8080/tcp"
How can I get the values of dynamically changing key like ("8125/udp","8134/udp", etc...)
Note: I'm using gson library for parsing
After modification
public static void main(String args[])
{
try
{
JsonParser parser = new JsonParser();
JsonObject obj=(JsonObject)parser.parse(new FileReader("sampleJson.txt"));
System.out.println("obj = "+obj);
JsonObject NetworkSettings_obj=(JsonObject)obj.get("NetworkSettings");
if(NetworkSettings_obj.has("Ports"))
{
JsonObject ntw_Ports_obj=(JsonObject)NetworkSettings_obj.get("Ports");
System.out.println("ntw_Ports_obj = "+ntw_Ports_obj);
Object keyObjects = new Gson().fromJson(ntw_Ports_obj, Object.class);
List keys = new ArrayList();
System.out.println(keyObjects instanceof Map); //**** here the statement prints false
if (keyObjects instanceof Map) // *** so controls doesn't enters into the if() condition block *** //
{
Map map = (Map) keyObjects;
System.out.println("Map = "+map);
keys.addAll(map.keySet());
String key = (String) keys.get(0);
JsonArray jArray = (JsonArray) ntw_Ports_obj.get(key);
System.out.println("Array List = "+jArray);
}
}
}
catch(Exception e)
{
}
}
You can do something like that (not tested but should be ok) :
if (ntw_Ports_obj.isJsonArray()) {
Iterator it = ntw_Ports_obj.getAsJsonArray().iterator();
while (it.hasNext()) {
JsonElement element = (JsonElement) it.next();
if(element.isJsonArray()){
JsonArray currentArray = element.getAsJsonArray();
// Do something with the new JsonArray...
}
}
}
So your problem is the key 8080/tcp is not fixed and it may change. when this situation you can try like this to get the value of the Dynamic key.
Set<Map.Entry<String, JsonElement>> entrySet = ntw_Ports_obj
.entrySet();
for (Map.Entry<String, JsonElement> entry : entrySet) {
String key = entry.getKey();
JsonArray jArray = (JsonArray) ntw_Ports_obj.get(key);
System.out.println(jArray);
}
Edit:
Object keyObjects = new Gson().fromJson(ntw_Ports_obj, Object.class);
List keys = new ArrayList();
/** for the given json there is a one json object within the 'Ports' so the 'keyObjects' will be the 'Map'**/
if (keyObjects instanceof Map) {
Map map = (Map) keyObjects;
keys.addAll(map.keySet());
/**
* keys is a List it may contain more than 1 value, but for the given
* json it will contain only one value
**/
String key = (String) keys.get(0);
JsonArray jArray = (JsonArray) ntw_Ports_obj.get(key);
System.out.println(jArray);
}

Convert JSON object with duplicate keys to JSON array

I have a JSON string that I get from a database which contains repeated keys. I want to remove the repeated keys by combining their values into an array.
For example
Input
{
"a":"b",
"c":"d",
"c":"e",
"f":"g"
}
Output
{
"a":"b",
"c":["d","e"],
"f":"g"
}
The actual data is a large file that may be nested. I will not know ahead of time what or how many pairs there are.
I need to use Java for this. org.json throws an exception because of the repeated keys, gson can parse the string but each repeated key overwrites the last one. I need to keep all the data.
If possible, I'd like to do this without editing any library code
As of today the org.json library version 20170516 provides accumulate() method that stores the duplicate key entries into JSONArray
JSONObject jsonObject = new JSONObject();
jsonObject.accumulate("a", "b");
jsonObject.accumulate("c", "d");
jsonObject.accumulate("c", "e");
jsonObject.accumulate("f", "g");
System.out.println(jsonObject);
Output:
{
"a":"b",
"c":["d","e"],
"f":"g"
}
I want to remove the repeated keys by combining their values into an array.
Think other than JSON parsing library. It's very simple Java Program using String.split() method that convert Json String into Map<String, List<String>> without using any library.
Sample code:
String jsonString = ...
// remove enclosing braces and double quotes
jsonString = jsonString.substring(2, jsonString.length() - 2);
Map<String, List<String>> map = new HashMap<String, List<String>>();
for (String values : jsonString.split("\",\"")) {
String[] keyValue = values.split("\":\"");
String key = keyValue[0];
String value = keyValue[1];
if (!map.containsKey(key)) {
map.put(key, new ArrayList<String>());
}
map.get(key).add(value);
}
output:
{
"f": ["g"],
"c": ["d","e"],
"a": ["b"]
}
In order to accomplish what you want, you need to create some sort of custom class since JSON cannot technically have 2 values at one key. Below is an example:
public class SomeClass {
Map<String, List<Object>> values = new HashMap<String, List<Object>>();
public void add(String key, Object o) {
List<Object> value = new ArrayList<Object>();
if (values.containsKey(key)) {
value = values.get(key);
}
value.add(o);
values.put(key, value);
}
public JSONObject toJson() throws JSONException {
JSONObject json = new JSONObject();
JSONArray tempArray = null;
for (Entry<String, List<Object>> en : values.entrySet()) {
tempArray = new JSONArray();
for (Object o : en.getValue()) {
tempArray.add(o);
}
json.put(en.getKey(), tempArray);
}
return json;
}
}
You can then retrieve the values from the database, call the .add(String key, Object o) function with the column name from the database, and the value (as the Object param). Then call .toJson() when you are finished.
Thanks to Mike Elofson and Braj for helping me in the right direction. I only wanted to have the keys with multiple values become arrays so I had to modify the code a bit. Eventually I want it to work for nested JSON as well, as it currently assumes it is flat. However, the following code works for what I need it for at the moment.
public static String repeatedKeysToArrays(String jsonIn) throws JSONException
{
//This assumes that the json is flat
String jsonString = jsonIn.substring(2, jsonIn.length() - 2);
JSONObject obj = new JSONObject();
for (String values : jsonString.split("\",\"")) {
String[] keyValue = values.split("\":\"");
String key = keyValue[0];
String value = "";
if (keyValue.length>1) value = keyValue[1];
if (!obj.has(key)) {
obj.put(key, value);
} else {
Object Oold = obj.get(key);
ArrayList<String> newlist = new ArrayList<String>();
//Try to cast as JSONArray. Otherwise, assume it is a String
if (Oold.getClass().equals(JSONArray.class)) {
JSONArray old = (JSONArray)Oold;
//Build replacement value
for (int i=0; i<old.length(); i++) {
newlist.add( old.getString(i) );
}
}
else if (Oold.getClass().equals(String.class)) newlist = new ArrayList<String>(Arrays.asList(new String[] {(String)Oold}));
newlist.add(value);
JSONArray newarr = new JSONArray( newlist );
obj.put(key,newarr);
}
}
return obj.toString();
}
