JSON to XML Converter
Turn any valid JSON into clean, standards-friendly XML in one click
What is a JSON to XML Converter?
I love how JSON keeps data light and friendly for JavaScript, yet some legacy systems still expect XML. When your shiny front-end meets an older partner, you need a translator. A JSON to XML converter takes your modern JSON and turns it into well-formed XML so both systems can talk without arguing about syntax.
What Does Our JSON to XML Converter Do?
This web tool reads any valid JSON object or array, parses it in-browser, and outputs neat XML. It uses the open-source x2js library, which is battle-tested in production apps. There is no server call, so your data never leaves your machine. You get instant results and full privacy in one click.
What to Expect When Using This Tool
A clean grey-white interface shows two big boxes. Paste JSON in the top box, click Convert JSON, and see XML appear below. If your JSON is invalid you get a helpful error explaining why. Everything adjusts gracefully on mobile. A Clear All button gives you a fresh slate after each test.
Common Use Cases
- Enterprise Integration – Many banks and government APIs still accept only XML payloads. I paste my JSON, convert it, and send the XML without rewriting my whole stack.
- Configuration Files – Some software wants XML config, yet my deployment scripts produce JSON. This tool bridges that gap.
- Teaching and Demos – Showing students the structural differences between JSON and XML becomes much clearer with real-time conversion.
- Debugging Mixed Stacks – Front-end logs JSON while server logs XML. I convert on the fly to compare data points.
- Rapid Prototyping – When I mock an API, I may store data in JSON but need to hand off XML samples to another team.
Notice how arrays become repeated XML elements while primitive values stay inside simple tags.
What if my JSON is invalid?
The tool shows an error with the exact line and character position. Fix the typo and try again.
Does it handle nested arrays?
Yes, nested arrays become nested XML child elements.
How does it treat null values?
Null values become self-closing tags for brevity.
Can I use this offline?
After the page loads once, your browser cache keeps the library so the tool works without internet.
Is the output formatted?
The XML is indented for readability. You can minify it later if needed.
What about attributes in JSON?
JSON has no attributes. If you need attributes you can wrap values in objects with a predefined _attr key then post-process.
Is my data secure?
Everything happens in your browser memory. No transmission means total privacy.
Can it convert huge files?
Large files depend on your browser memory. For megabyte-scale data try a command-line tool.
Does it escape special characters?
Yes, the x2js library escapes <, >, and & automatically.
Can I automate this in my own code?
Include x2js from a CDN and call json2xml_str(yourObj) just like the tool does.
Benefits of Using Proper XML
XML may feel chatty, yet it remains dominant in many business protocols. Properly formatted XML supports namespaces, validation, and long-standing schemas. Once your JSON converts faithfully, you gain compatibility with SOAP services, legacy databases, and enterprise queues without sacrificing JSON in your modern stack.
Best Practices
- Validate JSON before conversion with a linter.
- Use consistent key naming to avoid surprise tag names.
- Keep arrays homogeneous for predictable XML.
- Backup original JSON before mass conversion especially in production pipelines.
- After conversion, test XML against a schema if one is provided by the receiving system.
Getting Started
- Scroll to the JSON to XML Converter above.
- Paste or type your JSON into the first textarea.
- Click Convert JSON.
- Copy the XML from the second textarea.
- Use it in your API call, configuration file, or batch script.
- Press Clear All to reset and convert something else.
This tool keeps your workflow smooth by letting modern JSON chat easily with classic XML. Give it a spin and keep building without friction.
