JSON to XML Converter
Serialize JSON into XML.
How to use JSON to XML Converter
Convert a JSON object or array into a nested XML string.
Open JSON to XML Converter on toolpermarket and fill in the inputs the tool asks for.
In the JSON field, paste a JSON object or array to serialize. A top-level array becomes repeated <item> elements.
Press Convert to compute the result. The output appears immediately below the form. Adjust the inputs and recalculate as many times as you need.
Read the result and use it as needed. If the number looks off, re-check your inputs and run it again — the math is deterministic, so the same entries always return the same answer.
Worked example. Paste {"root":{"name":"Jane","age":30}} to get <root><name>Jane</name><age>30</age></root>.
Tips for accurate results.
Every key becomes a wrapping tag.
Arrays become repeated child elements with a shared name.
Null values are emitted as empty tags.
When to use JSON to XML Converter. Feeding JSON into an XML-consuming API. Generating sample SOAP-style payloads. Converting config between formats.
When you actually reach for this
- A legacy system or SOAP endpoint only accepts XML and you have JSON to send it.
- You need a config file in XML format generated from a JSON source.
Where this tool stops being accurate
- JSON arrays of objects become repeated elements, but the order and singular/plural naming depend on the converter's conventions.
- XML requires a single root element, so a top-level JSON array is wrapped, which the consumer must expect.
Frequently asked questions
How are arrays handled?
A JSON array is turned into repeated elements that share the parent key as their tag name, so a list of users becomes several <user> nodes.
What about nested objects?
Each object is serialized recursively, so a value that is itself an object becomes a child element containing its own sub-elements.
Are values escaped?
Special characters in text are escaped as XML entities so the output stays well-formed; numbers and booleans are written as their string form.
My array turned into repeated tags but the consumer wants a list wrapper — how?
That is a naming/structure choice the receiver defines; wrap the items under a parent element or rename the array key to match their schema.
Why is there an extra root node?
XML must have exactly one root, so a JSON array or object set is wrapped in a single element. Strip or rename it on the consumer side if needed.
