About JSON to XML

JSON to XML Converter transforms JSON data into well-formed XML markup instantly in your browser. JSON object keys become XML element names, values become element text content, and arrays are expanded into repeated sibling elements — making JSON data consumable by XML-based APIs, enterprise services, and legacy systems.

This tool bridges two of the most widely used data interchange formats. Many enterprise systems, SOAP web services, and document processing pipelines require XML, while modern APIs serve JSON. Converting between them manually is error-prone and tedious — this tool does it accurately in seconds.

All conversion runs entirely in your browser with no server needed. The output is formatted and indented for readability, and you can copy or download it directly.

Key Features of JSON to XML

  • Convert JSON objects and arrays to well-formed XML elements
  • JSON keys become XML element tag names
  • Arrays are expanded into repeated sibling elements
  • Formatted XML output with proper indentation
  • Handles nested objects and mixed-type arrays
  • Works entirely in-browser — no server uploads
  • One-click copy or download of XML output
  • Validates JSON input before converting

Supported Formats

JSON objectsJSON arraysNested JSON structures

Output Formats

Well-formed XML with proper indentation

XML element names must be valid identifiers. JSON keys that start with numbers or contain spaces will be sanitized or wrapped.

Examples

Convert a user object to XML

Transform a JSON API response into XML for use with a legacy SOAP service.

Input

{"user":{"id":1,"name":"Alice","active":true}}

Output

<user>
  <id>1</id>
  <name>Alice</name>
  <active>true</active>
</user>

Convert a JSON array to repeated XML elements

Represent a list of items as sibling XML elements.

Input

{"items":["apple","banana","cherry"]}

Output

<items>
  <item>apple</item>
  <item>banana</item>
  <item>cherry</item>
</items>

Common Use Cases

  • Preparing JSON API responses for submission to SOAP-based web services
  • Converting JSON configuration data to XML for enterprise middleware
  • Bridging modern REST API output with legacy XML-consuming systems
  • Generating XML data fixtures for testing XML parsers and validators
  • Converting JSON exports to XML for import into CMS or ERP systems
  • Producing XML from JSON for RSS or Atom feed generation workflows

Troubleshooting

Invalid XML element name from a numeric JSON key

Solution

XML element names cannot start with a number. JSON keys like '123' will be wrapped in a generic element name. Rename your JSON keys to start with a letter.

Array items appear with generic item element names

Solution

JSON arrays are mapped to repeated elements with a generated name (e.g., <item>). Rename the array key in your JSON to control the parent element name.

Conversion fails with a JSON syntax error

Solution

Validate your JSON first using the JSON Validator tool. Common issues include trailing commas, single-quoted strings, or missing closing brackets.

Frequently Asked Questions

Is the conversion lossless?

JSON to XML conversion preserves all values and the document structure. However, JSON type information (string vs number) is not retained in XML, which represents all content as text.

Can I convert XML back to JSON?

Use the XML Formatter tool which includes a Convert to JSON feature. For bidirectional workflows, maintain one format as the source of truth.

What happens to JSON null values?

JSON null values are converted to empty XML elements (e.g., <field/>). The semantics of null are lost in XML since XML does not have a native null type.

How are JSON arrays handled in XML?

JSON arrays become repeated sibling XML elements. For example, ["a","b"] under a key "items" produces <item>a</item><item>b</item> inside an <items> parent.

Can I specify a root element name?

The root element name comes from the top-level JSON key. Wrap your JSON in an outer object with the desired root name, e.g. {"myRoot": {...}}.

Does the output include an XML declaration?

The tool produces the XML element tree. You can prepend <?xml version="1.0" encoding="UTF-8"?> manually if your target system requires it.

Is my data sent to a server?

No. All conversion is performed locally in your browser. Your JSON data never leaves your device and is not transmitted or stored.

What if my JSON key contains spaces or special characters?

XML element names cannot contain spaces or most special characters. The converter will sanitize invalid characters. Rename your JSON keys to use letters, numbers, hyphens, or underscores only.
