JSON to XML Converter Online

Convert JSON to XML format. Fast, secure, and completely free. All processing happens in your browser — no data is sent to any server.

What is JSON to XML?

JSON to XML conversion takes a JSON object and produces an equivalent XML document, mapping object keys to element names and array items to repeated sibling elements. Since XML requires every value to live inside a named element (unlike JSON, where a bare array or primitive is valid on its own), this conversion needs a root element and a defined convention for how things like arrays get represented — decisions this tool makes consistently so the output is valid, well-formed XML every time.

How to Use JSON to XML

1. Paste your JSON object into the input panel
2. Click 'Convert' to produce the equivalent XML document
3. Specify a root element name if you want something other than the default
4. Review how arrays were converted into repeated sibling elements
5. Copy the resulting XML for use in a SOAP request, config file, or legacy system integration

Key Features

• Converts JSON objects and arrays into well-formed XML with a defined root element
• Configurable root element name
• Converts array items into repeated sibling elements automatically
• Handles nested objects with correct element nesting
• Runs entirely client-side

Why Use JSON to XML?

Integrating with a legacy system, a SOAP-based API, or any XML-only interface often requires sending data as XML even when it's easiest to construct that data as JSON first, especially when building it from a JavaScript application or a modern API response. This conversion handles the structural translation — deciding how arrays and nested objects become valid XML — so you don't have to manually write XML-building code for a data shape you already have modeled as JSON.

Common Use Cases

• Preparing a JSON payload to send to a legacy SOAP or XML-only API
• Converting JSON configuration data into an XML format required by an older system
• Generating XML test fixtures from JSON data you already have on hand
• Building an XML export from a JSON-based data source
• Migrating a JSON-based config to an XML-based system during an integration project

Frequently Asked Questions

Why does XML need a root element when JSON doesn't require one?

XML's specification requires exactly one top-level element containing everything else; JSON allows a bare object, array, or even a primitive value at the top level, so converting to XML requires wrapping the data in a root element you can name.

How are JSON arrays represented in the resulting XML?

Each array item becomes a repeated sibling element with the same tag name, since that's the closest XML equivalent to a JSON array of values.

What happens to JSON values like true, false, or null?

They're converted to their text representation within an element (like <active>true</active>), since XML has no native boolean or null type distinct from element text content.

Can I customize the element names used for array items?

Depending on the tool's configuration options, you can often specify a naming convention for array item elements rather than relying purely on the default.

Is the resulting XML guaranteed to be well-formed?

Yes, the conversion always produces valid, well-formed XML with proper escaping of special characters within element content.
