I built this converter because I was tired of the existing ones being so bad. You know how it goes – you need to turn JSON into XML, you find some tool online, and it either messes up your data or throws it into a pile of pointless tags. I've probably used a bunch of converters over the years, and they all seem to have the same issues. So, I decided to create one that just works the way it should.
What Makes My Tool Different?
Most converters are a mess. They take your neat JSON and turn it into oversized XML with all kinds of extra stuff. Mine actually tries to figure out what you need.
If you have JSON keys like id, category, or anything that starts with @, it turns them into XML attributes automatically. So {id: 123, name: Soniya} becomes Soniya instead of the clunky <root>123Soniya.
Plus, you can set your own root element name. If you're working with products, you can call it products. If it's users, call it users. It's simple, but other tools don't seem to get it right.
How I Made it Smart
The code checks each JSON key and then decides what to do:
- id and category become attributes.
- Keys that begin with @ become attributes (without the @).
- Everything else becomes a regular child element.
This follows the XML standards that make sense. Seeing just feels right. And the tool goes both ways – JSON to XML and back. When converting XML to JSON, it keeps the attributes nice and tidy in an @attributes object, which is what most parsers expect anyway.
Clean Results
I can't stand tools that just keep adding wrapper elements. My converter puts your data right into the root element you pick. No dealing with wrappers you don't want.
For arrays, it's smart about naming. If your root is products, each item becomes a product. It’s basic logic that works. I also made sure it handles null values and empty arrays because the real world isn't always perfect, and your converter should be able to deal with that.
Everything Stays on Your Computer
There aren't any servers involved here. Your data never leaves your browser. I don't want to see it, and you probably don't want me to see it either.
** Technical Info**
It just use the built-in browser stuff - DOMParser for XML, JSON.parse for JSON. No outside stuff to slow things down or break. The other special characters are handled correctly, too, so your data doesn't become ruined. I spent way too much time testing with things like null values and empty arrays, but it works well now.
Converting XML to JSON? It organizes attributes in an @attributes object and handles mixed content, too. The parser will work with almost any XML you give it. I even made sure it could handle bad XML – not perfectly, but it tries to make sense of it instead of just breaking down.
When I Use It
- APIs that want XML, but I only have JSON
- Config file conversions
- Testing XML schemas with JSON
- Taking data between systems
- Quick debugging when I need to see data differently
- Working with old systems that only take XML
That debugging thing happens more than you might think. Sometimes, you just need to see your JSON as XML to figure out what's wrong. And those old systems are everywhere, and they all want XML for some reason.
Simple to Use
Pick your input type, paste your data, set the root name if you need to, and hit convert. The result shows up, you copy it, and you're done. No confusing menus or options nobody uses.
I added a reset button because reloading the page can be annoying. It's a small thing, but it it's there now. I also made sure the copy button does what it's supposed to – you'd be surprised how many tools screw that up.
Why Keep It Simple?
Those tools for enterprises have 50 different settings. But, usually, you want to turn your data with having special education in XML process. I kept the interface simple - just what you might need.
The automatic attribute mapping takes care of most situations. Clean output means no need to fix it later. Since it runs in your browser, there's nothing to set up. And it's fast – conversion is instant, even with bigger JSON files.
Give It a Shot
If you're always turning JSON and XML try this out.

It's fast, private, and makes clean results that follow normal XML standards. No signup, no limits. It works on your phone, too, if you need to convert something while you're out and about. The site changes for those smaller screens so it can be useful.
The smart way for attribute mapping helps on every change. Instead of fixing the output, your XML is ready for use. I use it now on a daily basis for different plans.Sometimes I convert data to see different sides.
Let me know if it helps you, or if you need other things. I made this for my own use, but other coders might need different stuff. I'm always open to hearing back from people. The better plans usually come from how people use them that I never knew about.
