Imagine a situation in which a client wants to receive specific frog data from a server. Figures 1 and 2 (below) provide representations of this data in XML and JSON format respectively.
XML is better at handling more complex scenarios involving schema and implementing strict data constraints . Unlike JSON (a simple data exchange language), XML is a markup language. Because of that, it’s important to note that this article is strictly comparing XML vs JSON in regards to their data exchange capabilities. XML data structuring capabilities are much greater, offering representation of many more data types in comparison to JSON. It can include images, charts, and graphs on top of the number and text types supported by JSON. XML also supports comments and namespace, and even contains display capabilities.
To summarize the key differences between XML and JSON, Figure 3 (below) has been provided.
Again, when deciding whether or not to use XML or JSON files for data interchange, one must consider their application. It’s up to the developer to decide what functionality their application requires. If the data is simple and doesn’t require complex schema or data constraints, then JSON is typically advantageous. Although JSON may have more functionality limitations, its lightweight nature offers the advantage of speed. If the data requires a little more functionality and data structuring, the developer should consider implementing XML.
