A few months ago, I was stuck integrating a client’s platform with this ancient SOAP API. I'm not even kidding, the documentation looked like it was hosted on a GeoCities page from 2004.
To be fair, the API actually worked, but it threw a massive wrench into our stack. Our Laravel backend, the frontend, the mobile apps—literally everything we built—speaks fluent JSON. Meanwhile, this legacy behemoth kept spitting out payloads that looked like this:
<User>
<Id>101</Id>
<Name>John Doe</Name>
<Email>john@example.com</Email>
</User>
The data was fine, but the format was just a pain in the ass to deal with. Before I could even start writing the actual business logic, I had to stop and build a parsing bridge just to get the data into a format our apps could actually use without choking.So, before I could even touch the actual business logic, I had to stop and build a bridge. That meant converting that XML into JSON right at the ingestion point. It made me realize just how often modern developers still face this exact hurdle.
Isn’t Everything JSON by Now?
You’d think so. If you’re building greenfield web apps today, JSON is the undisputed default. But out in the wild, XML is incredibly resilient. It’s still the bedrock of:
- Banking & Financial Integrations: Core banking systems love XML.
- Government & Enterprise Services: Legacy infrastructure that simply won't be rewritten anytime soon.
- SOAP APIs & B2B Gateways: Standard enterprise middleware.
- Everyday Web Essentials: RSS feeds and sitemaps aren't going anywhere.
Sooner or later, no matter how modern your stack is, you will run into an XML wall. And your first instinct will almost certainly be to turn it into JSON.
The Real Benefit of Flipping the Format
JSON is just infinitely easier to manipulate in modern programming environments. Instead of wrestling with DOM nodes, attributes, text nodes, and complex namespaces, you get a clean, native object.
Take that user snippet from earlier. Once converted, it becomes a clean, readable object:
{
"Id": 101,
"Name": "John Doe",
"Email": "john@example.com"
}
Suddenly, the data is ready to be passed around your ecosystem without requiring specialized parsing logic at every step. It makes debugging enterprise integrations, processing payment responses, or building REST wrappers over legacy systems so much smoother.
Automating the Chore
Years ago, I’d write a quick, throwaway script every time I hit an XML payload, and then waste another ten minutes formatting the output to make sure it looked right. Eventually, you realize that rewriting the same utility script for every new project is a massive waste of mental bandwidth. It really should just be a one-click task.
That’s exactly why we built an XML to JSON Converter into Fixzi.ai. We wanted to eliminate those friction points from the daily developer workflow. Instead of writing custom parsers just to inspect a response, you can drop your XML in and instantly get clean, structured JSON.
Ultimately, XML isn't dying anytime soon—especially in enterprise tech. But that doesn’t mean your modern application needs to suffer through it. Converting it at the gate is the fastest way to make legacy systems play nice with modern code.
What about you? What’s the last project where XML unexpectedly crashed the party?

JSON can only do a subset of what XML can do. If you don't need different character sets, entities, validation schemes, transformations, processing instructions, then JSON is fine. Converting XML to JSON is trivial, but if you stick with XML, your application could be simpler and more powerful.
