What Is TOON to XML?
If you've been generating structured data with TOON (Token-Oriented Object Notation) — the compact LLM-friendly format — and need to pipe it into an XML-based system, you'll hit friction fast. XML powers SOAP web services, RSS and Atom feeds, and countless enterprise integrations. This tool converts TOON to well-formed XML entirely in your browser — nothing is uploaded to any server. The W3C XML specification defines exactly how the output is structured. For a deeper look at how data serialization works across formats, see the MDN guide to structured data.
Your TOON is parsed and re-emitted as equivalent XML right on this page, without a server involved. The W3C XML spec defines the output format. For JSON instead, use TOON to JSON.

How to Use This Tool
Paste or Upload TOON
Copy your TOON and paste it into the left editor. You can also click Upload to load a .toon or .txt file. The Sample button loads example data. Invalid TOON will show an error.
View XML Output
Converted XML appears on the right: TOON keys turn into elements and nested objects into child elements. Broken TOON produces an error there instead.
Copy or Download
Use Copy or Download. For TOON to JSON, use TOON to JSON. For TOON formatting, use TOON Formatter.
When you receive TOON from an LLM or AI system but need to feed it into an XML-based pipeline (SOAP, enterprise integration, or legacy systems), this conversion helps. XML is widely supported. Converting here gives you valid, well-formed XML.

Frequently Asked Questions
Is it safe to paste private TOON data here?
Yes, completely. The conversion runs entirely inside your browser. Nothing you type is sent to our servers — your data stays on your device.
What's the practical difference between TOON and XML?
TOON is a compact, token-friendly format built for LLM output — concise and easy to generate. XML is verbose and hierarchical, used everywhere from SOAP APIs to RSS feeds. Use this tool when your source is TOON but the downstream system expects XML.
Does the conversion preserve the full structure?
Yes. TOON objects become XML elements, arrays become repeated sibling elements, and string/number/boolean values become text content. Nested structures are handled correctly throughout.
Can I convert to JSON instead of XML?
Absolutely. Use TOON to JSON for JSON output. Both conversions are lossless.
What happens to XML attributes in the conversion?
The default conversion maps TOON values to XML element text content rather than attributes. If you need a specific attribute-based schema, you'll want to post-process the XML output.
