How to convert XML to JSON in Node.JS

The process of converting between XML and JSON formats is generally a rather dry and tedious undertaking. To counter this drudgery, I’m going to show you how to apply an API to the situation, allowing us to save a huge amount of time and effort.

Installation of the client that we need can be carried out by dropping this reference into our package.json file.

"dependencies": {
    "cloudmersive-convert-api-client": "^2.1.6"
  }

Next step, call convertDataXmlToJson.

var CloudmersiveConvertApiClient = require('cloudmersive-convert-api-client');
var defaultClient = CloudmersiveConvertApiClient.ApiClient.instance;
// Configure API key authorization: Apikey
var Apikey = defaultClient.authentications['Apikey'];
Apikey.apiKey = 'YOUR API KEY';
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
//Apikey.apiKeyPrefix = 'Token';
var apiInstance = new CloudmersiveConvertApiClient.ConvertDataApi();
var inputFile = "/path/to/file"; // File | Input file to perform the operation on.
var callback = function(error, data, response) {
if (error) {
console.error(error);
} else {
console.log('API called successfully. Returned data: ' + data);
}
};
apiInstance.convertDataXmlToJson(inputFile, callback);

With our function set up, we just have to provide an XML file and let our API go to work on it, returning us the JSON. Simple.
