JSON Object Example

A complex JSON object with nested structures that can be converted to XML

{
  "users": [
    {
      "id": 1,
      "name": "John Doe",
      "email": "john@example.com",
      "profile": {
        "age": 30,
        "city": "New York",

          "notifications": true
        }
      }
    },
    {
      "id": 2,
      "name": "Jane Smith",
      "email": "jane@example.com",
      "profile": {
        "age": 25,
        "city": "Los Angeles",

Frequently Asked Questions

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data interchange format used to store and transmit structured data. It's easy for humans to read and write, and easy for machines to parse and generate. JSON is commonly used in Web APIs, configuration files, and database data interactions.

What is XML?

XML (eXtensible Markup Language) is a markup language used to represent and transmit structured data. It describes data hierarchy relationships using tags and is a common format for many enterprise systems, documents, and configuration files.

What is JSON to XML conversion?

JSON to XML conversion is the process of transforming JSON data structures into XML format. This helps developers transfer data between different systems or platforms, such as from modern APIs (using JSON) to legacy systems (using XML).

Why convert JSON to XML?

Common use cases include: compatibility with legacy systems, system integration bridging APIs and web services, data migration and archiving, and cross-platform sharing where some tools only support XML input.

What features does this online tool support?

This tool supports: instant JSON to XML conversion, JSON file upload or direct text paste, URL data loading, one-click copy/download/share XML output, automatic output formatting, and support for all standard data types including arrays, nested objects, booleans, numbers, and null values.

Is the tool free?

Yes! JsonWork's JSON to XML tool is completely free - no registration, no login, no ads, no upload limits.

Is my JSON data stored?

No. All processing happens locally in your browser using JavaScript. Your data is never uploaded or stored, ensuring your privacy and security are always protected.

How to load JSON from a file?

You can load JSON in two ways: 1) Click the 'Upload File' button to select a local .json file, or 2) Paste JSON data directly into the input box.

Can I load JSON from a URL?

Yes! Click the 'Import from URL' button above the input box, paste the online address of the JSON file, and click 'Submit'. The system will automatically fetch the data and convert it.

Can I download the converted XML?

Yes! After conversion, click 'Download XML' to save as a .xml file. You can also click 'Copy' to copy the content or 'Share' to generate a shareable link.

How are JSON arrays handled?

JSON arrays are automatically expanded into multiple XML elements. For example, {"fruits": ["apple", "banana"]} becomes <root><fruits>apple</fruits><fruits>banana</fruits></root>.

Does it support nested JSON?

Yes! No matter how deeply nested the JSON is (objects within objects, arrays within objects), the converter maintains complete data structure and automatically wraps it into valid XML.

Are boolean values, null, etc. preserved?

Yes! Booleans (true/false) are output as strings, and null values are converted to empty tags like <value />.

What about special characters in JSON keys?

To ensure XML validity, the tool automatically replaces illegal characters. If a key starts with a number or symbol, it adds a '_' prefix to ensure the generated XML can be read normally by standard parsers.

How to ensure the output is valid XML?

The tool automatically validates XML syntax after conversion and adjusts tag structure when necessary (such as auto-closing missing tags).

Which systems and browsers are supported?

Compatible with all major operating systems and browsers: Windows, macOS, Linux, Chrome, Firefox, Edge, Safari.

Can I do reverse conversion (XML → JSON)?

Yes! You can use the XML to JSON online tool to complete reverse conversion, achieving bidirectional data exchange.

Can I do batch conversion?

Currently only single file or single input conversion is supported. Batch conversion functionality (automatic multi-file processing) is under development and expected to be released in future versions.

Can I preview the converted XML online?

Yes! After conversion, you can directly view the formatted XML output below the page, with support for copy and collapsible display.

Does the conversion result include XML attributes?

By default, no. JsonWork uses a concise mode (Tag-based XML) that only generates tag content. Future versions will support optional 'Attribute mode' output format.

Does the generated XML have a root node?

Yes. The tool automatically adds a <root> root node to ensure the output XML is a valid single-root document.

Can I use it on mobile devices?

Absolutely! The tool runs smoothly on mobile and tablet browsers, supporting touch paste, file selection, and long-press copy.

Is the tool output editable?

Yes! The generated XML can be directly edited in the result box, supporting manual adjustments before downloading again.

What to do if errors occur?

If you encounter 'Invalid JSON' or 'Conversion Failed': 1) Check if the JSON format is correct, 2) Use a JSON validator to confirm no syntax errors, 3) Try converting again.

What character encodings are supported?

Default output is UTF-8. All Unicode characters (including Chinese, Japanese, Korean, Emoji) are correctly encoded and displayed.
