Json To Xml Converter — Free Online Tool

A JSON to XML converter transforms JSON data into well-formed XML documents. Developers use it when integrating with SOAP APIs, legacy systems, or XML-based configuration formats that require structured XML input from JSON data sources.

Features

• Configurable root element: Set a custom root element name to match your XML schema requirements.
• Pretty printing: Format output with configurable indentation for readability.
• Nested structure support: Deeply nested JSON objects and arrays convert into proper XML element hierarchies.
• Local-first — data never leaves your browser: All processing happens client-side for complete privacy and security.

Frequently Asked Questions

How are JSON arrays converted to XML?

Array items become repeated XML elements. The element name is derived from the parent key.

Does it add an XML declaration?

The tool generates the XML body. Add <?xml version="1.0"?> manually if your system requires it.

Can I convert JSON with special characters?

Yes. Special characters are properly escaped using XML entities (&amp;, &lt;, etc.).

Does it preserve JSON data types in XML?

XML is text-based, so all values become text content. Numbers, booleans, and nulls are serialized as their string representations.

Can it handle deeply nested JSON?

Yes. The converter recursively processes any depth of nesting, creating matching XML element hierarchies.

Is this tool free?

Yes, this tool is completely free with no usage limits, no ads, and no account required.

Does it work offline?

Yes. Once the page loads, all processing happens locally in your browser — no internet connection needed.

Is my data safe with this tool?

Absolutely. Your data never leaves your browser. Everything is processed client-side with zero server uploads.
