How to Use JSON to XML

1

Paste your JSON into the editor, or upload a .json file of up to 10 MB.

2

Pick the root element name and decide whether keys such as id or href should become XML attributes.

3

Click the "Process" button to serialise the document into indented, well-formed XML.

4

Copy the XML or download it as a .xml file, then validate it in your API client or editor before sending.

Frequently Asked Questions

Nothing at all. It is free with no sign-up and no daily limit, so you can use it as often as you like for client work or internal scripts.
No. Conversion happens in your browser and the data is discarded when the page is closed. Nothing about your payload is stored or logged.
Each array becomes a repeated element, typically a set of item nodes with one entry per array item. Repeated siblings keep the array structure intact so the XML round-trips back to the same data.
They are turned into valid XML element names by stripping illegal characters and joining the rest, with the original text kept as an attribute where possible. Names that clash with reserved XML words are adjusted automatically.

About JSON to XML

Not every system can ingest JSON. SOAP endpoints, legacy .NET and Java services, sitemaps, RSS feeds, bank and insurance integrations and plenty of older enterprise software all insist on XML. The JSON to XML converter takes a JSON document and serialises it into well-formed XML, mapping object keys to elements, array items to repeated item nodes, and primitive values to text content.

You get a clean declaration at the top, consistent indentation and escaped entities for ampersands, angle brackets and quotes, so characters that would otherwise break the document are written safely. Special key names such as id, type or href can be promoted to XML attributes instead of child elements, which is what most SOAP and sitemap schemas actually expect.

It is the natural companion to the XML to JSON converter: inspect a SOAP request, port a JSON config into a system that only reads XML, or generate a feed or sitemap skeleton from a data structure. Files up to 10 MB are processed locally in your browser, so client records and internal payloads never leave your machine.

When to Use This Tool

  • Building a SOAP or legacy XML request payload from a JSON body
  • Generating an XML sitemap, RSS or Atom feed from structured data
  • Feeding a JSON config into a .NET or Java service that only reads XML
  • Validating how a JSON structure will look as an XML tree before integrating it
  • Creating sample or mock XML payloads for developers and testers
