JSON to XML

Processed locally

app.xml.view

You can also load data via #data={"name":"Ada"} or #url=... It is cleared from the address bar after it is read.

Convert JSON and XML both ways. When an older API still returns XML, or you need JSON for a system that only accepts XML, convert locally first to inspect the structure. The root element name is editable; the default is root。

Two-way

JSON → XML or XML → JSON. Useful to see how fields map to tags, not as a one-shot production conversion.

After converting, run the target system’s validator as well.

Approximate structure

Objects become nested elements; arrays usually become repeated tags. That is a common convention and may not match the other party’s schema.

Whether something is an attribute or a child element varies by system—spot-check.

Attributes and text

How XML attributes and text nodes appear in JSON may not match the original system exactly. Spot-check after converting.

Namespaced SOAP documents rarely convert perfectly on autopilot.

Example

JSON

{
  "note": {
    "to": "Ada",
    "body": "hello"
  }
}

XML (illustrative)

<note>
  <to>Ada</to>
  <body>hello</body>
</note>

Are namespaces kept?

Review complex SOAP / xmlns documents by hand. Automatic conversion rarely preserves every namespace detail.

YAML or XML?

Modern config often uses YAML. Enterprise buses and some payment or government APIs still use XML.

What is the root element name for?

JSON has no single “root tag.” When converting to XML, that name wraps the whole document.

Do I need to click convert?

Yes. Convert again after you change the root element name.

Recommended workflow

Paste JSON (or XML, if the page supports it) and set the root element name.
Click “Convert” and preview the tag structure.
Copy or download, then parse once in the target system.
If namespaces or attribute order matter, finish in a dedicated XML tool.

This page solves “see the structure first.” Do not rely on auto-conversion alone for strict XSD / SOAP.
