JSON to XML

Plenty of systems that predate REST still speak XML: SOAP endpoints, RSS and product feeds, enterprise message buses. When your data lives in JSON and the receiving side wants angle brackets, this json to xml tool makes the swap. Paste an object or array, click Convert to XML, and you get an indented document with the XML declaration on top and your nesting preserved. Arrays are wrapped as repeated item elements so lists survive the trip intact. It's a small, free json converter step that runs entirely in your browser, which matters when the payload is a client's order data.

How to use

01

Paste the JSON

An object or an array both work. Try sample loads a small book record if you'd like to see the element mapping before pasting your own data.

02

Click Convert to XML

The builder writes matching elements with a two-space indent and prepends the version 1.0 UTF-8 declaration. This is how you convert json to xml online with no upload.

03

Take the document

Copy the result and save it as a .xml file, or paste it wherever the legacy system expects markup. Rerun the conversion when the JSON changes.

Why JSON to XML

Common questions

How are arrays represented in the XML output?
A top-level array is wrapped in an items element containing one item element per entry, since XML needs a single root. Arrays nested inside objects become repeated elements as well. If the consuming system expects different element names, a quick find and replace on item is usually all it takes.
What declaration does the output start with?
Every result begins with the standard version 1.0, UTF-8 XML declaration, so validators and older parsers accept it as a complete document rather than a fragment. If you're embedding the output inside a larger document, drop that first line.
Are there limits or costs on this json to xml converter online?
No, it's free with no cap and no account. Payload size is bounded only by browser memory, and repeated conversions are instant because nothing round-trips to a server.
Can it turn plain text or images into XML?
No. A text to xml converter would need you to define elements for the text first, since XML requires named structure, and a jpeg to xml converter or image to xml converter isn't a real transformation: image pixels have no keys or hierarchy to map. This page needs structured JSON as its starting point.
Does an xml converter exist here for the reverse direction?
Yes, the XML to JSON page parses documents back into JSON, attributes included. Together the two form a full round trip, though heavily attribute-based XML converted to JSON and back may come out shaped differently than the original.
Where do I get a plain string instead of markup?
Different jobs, different pages. To convert json to string online, meaning escaped JSON inside a string value, start with the JSON Formatter. And if you want a json to text converter that produces flat human-readable rows, JSON to CSV outputs exactly that.
How should SOAP payloads be built with this?
It works well for the body: convert your JSON data here, then wrap the result in the envelope and namespace declarations your service definition requires. The tool doesn't generate SOAP envelopes itself, so keep a template for the outer layers and paste the converted body in.
