JSON vs XML: Which format should you choose?
Nov 05, 20255 min read
For years, XML (eXtensible Markup Language) was the king of data transport. Today, JSON reigns supreme. Let's look at why the industry shifted.
Comparison Table
| Feature | JSON | XML |
|---|---|---|
| Readability | High (Human readable) | Medium (Verbose tags) |
| Parsing Speed | Fast (Native in JS) | Slower (Requires XML DOM) |
| Data Types | Rich (String, Number, Array...) | Strings only (mostly) |
| Payload Size | Small (Lightweight) | Large (Closing tags add weight) |
The Verdict
Unless you are working with legacy enterprise systems (SOAP APIs) or require complex mixed-content documents, JSON is the clear winner for modern web APIs. It parses faster, uses less bandwidth, and maps directly to data structures in modern languages. If you need to convert between formats, try our JSON to XML Converter or JSON Formatter.
