Turning XML format into JSON Object in Java has many benefits. But, how do you do it properly?

XML and JSON are two of the most common coding languages ​​in website services. In other words, a lot of the web services, tools, and programs you use will either be in JSON or XML code. That’s why both these languages ​​are a prominent part of doing any web-based service.

But, the challenge is not using one of these languages ​​simultaneously. The challenge is turning one into the other or vice versa. Both languages ​​feature their independent parsers. Which gives the coder enough reason to use one or the other.

However, a split understanding tells us that JSON could be a little more efficient than XML. But, at the same time, it requires work and might even consume resources. So, how do you convert XML format into JSON objects?

Moreover, is it even worth it? Let’s find out.

What is XML?

Extensible Markup Language — a unique code that has allowed many great programs to exist. While it was extensively employed only after the release of Windows 7, the language itself has been around for more than 24 years. Or, since 1998.

The markup language, as the name suggests, is a file format for storing and transmitting data. This is particularly handy for transmitting and reconstructing random or arbitrary data. Hence, why it’s used in web-based services more than downloadable or installed tools.

However, it’s ideal for tools that have to tend to both machine and human-readable documents. Therefore, a paraphraser, plagiarism checker, or tools of such kind will extensively employ this language.

Common traits of XML include:

  • Simplicity and flexible code
  • Easily readable text (code) for even non-coders
  • Made to tackle publishing challenges on bigger scales
  • W3C recommendation
  • Primarily to store and transmit data, ie, text
  • Similar traits to HTML, but much easier to read and code
  • Self-descriptive and explanatory code

The pre-defined nature of XML made it a great alternative to HTML. Thus, why many web-based services have employed it in the past few years. While the latest update of this markup language was over 14 years ago, it’s still going strong in many online services.

What is JSON?

JSON is an open-standard code primarily employed to transmit human-readable data to machines — and vice versa. Compared to XML, JSON is not that old as it was standardized only in 2013 despite being around since 2001.

However, instead of acting as a code or markup language, it’s an open-standard file format. In other words, it’s a language-independent data format that originates from JavaScript. The parsing JSON-format data technique is employed by many modern programming languages.

Hence, every file that consists of JSON code ends with the extension “.json” Much like its counterpart XML, the language also transmits arbitrary data for both human and machine readability. The common traits of this language include:

  • Shortened from JavaScript Object Notation
  • The lightweight format allows quicker transmitting & storing of data
  • Often employed in server-based apps or services to transfer data from a server to the website and vice versa
  • Self-describable and explanatory
  • Data is named in values ​​and pairs
  • Data is only separated by commas

The syntax makeup of JSON code allows it to be identical to other JavaScript Objects. Thus, its compatibility with mobile and web-based applications is far greater than any of its peers.

What is JSON Object?

JSON Object literals are accompanied by braces such as “,“ as this allows the literal nature of JSON code to execute tasks. These objects contain specific strings / data, which contain key values ​​and pairs. The keys and values ​​are separated only by a colon.

In order for JSON Object to execute particular actions, the keys need to be strings. On the other hand, the values ​​need to be a JSON-supported data type such as string, number, array, object, or null.

However, each key or pair value is separated by a comma instead of a colon.

Why Convert XML Into JSON Format?

There’s an argument in the coding community that emphasizes that it takes resources and time to convert XML into JSON. Thus, is it worth the time of a coder and the effort to do so? Since both have similar performance and parsing technology, is it more efficient to turn XML into JSON?

Here are a few reasons that tell us why:

In a bigger project, ie, a content-related web service, JSON would provide much greater speed mainly because of its simplicity. Instead of having to read complicated code, the computer would process it much faster if it was in JSON format.

Instead of telling a computer or devising specific elements of code, JSON code is much more action-centric. This directness saves a lot of time.

Instead of relying on various elements that are familiar with programming languages, JSON features a lot more directness. In other words, even a non-coder can see JSON code and understand what it’s for.

How To Convert XML Format Into JSON Object In Java?

Now that the intricacies are out of the way let’s talk about how you can actually convert XML into JSON. Here are two main ways:

1. Manually

You can employ Maven or any other coding tool that you wish for. Then, follow these steps:

  • Create a new project
  • Set dependency to pom.xml
  • Import org.json for JSON
  • Create string variable for XML
  • Now convert XML to JSON using “XML.to.JSONObject (XMLvariable)
  • Print JSONObject

2. Using an online XML to JSON converter

Another simple way to convert the xml files into json is to use XML to JSON converter which can do this conversion task in a single click. To learn how to convert files between these formats see the below process.

XML to JSON

As you can see, it’s self-explanatory. All you need to do is enter XML code on one side, and copy the converted code from the other.

This is much better than the manual version because it saves a lot of time. Furthermore, if you’re converting a large amount of code, then this is much better and easier to handle.

Conclusion

There’s your explanation of JSON and XML and why you should convert one to the other — including the way to do it. Therefore, understand your requirement and then use a converter or convert it manually if the code isn’t much.
