It can try node js convert xml to json , here I am giving an example that will convert small xml file to json data file or it can be displayed json data.

Here is my small xml file : 

<?xml version="1.0" encoding="UTF-8" ?>

<website>

<company>Php Dedicated Develpers</company>

<owner>Bhaskar Bhatt</owner>

<url>http://phpdedicateddevelopers.com</url>

<employee>

<firstname>John</firstname>

<lastname>Doe</lastname>

</employee>

<employee>

<firstname>John</firstname>

<lastname>Doe</lastname>

</employee>

</website>

Before we proceed further , we must know that the “XML2JS” module is installed,if it is not installed then
Please run below command to install xml2js module:

for windows:

npm install xml2js

for ubuntu:

sudo npm install xml2js

As if you have installed, it should be exist in node_modules >> xml2js module.

Now, we will create task.js which will have the  below code to convert xml to json using node.js.

var fs = require("fs");

var fileName = "web.xml";

var parser = require("xml2js");
//read xml file

fs.readFile(fileName, function(err, data) {

//converting xml to json

parser.parseString(data, function (err, result) {

//To store the json to file

fs.writeFile("data.json",JSON.stringify(result),function(err,response){

});

//To display the json

console.log(JSON.stringify(result));

});
});

Now, final step to run below code to convert xml to json.

node task.js
