When working with large or nested JSON files, you often end up with bloated data structures that take up unnecessary space. TOON short for Token-Oriented Object Notation provides a lightweight, tokenized alternative that’s faster to parse and easier to transmit.

That’s why we built the JSON TOON Converter at Scalevise: a free online tool that turns any JSON input into valid TOON syntax in seconds.

What is TOON?

TOON is a compact data format designed to reduce JSON overhead by 40-60% without sacrificing structure or readability.

Instead of traditional JSON braces and key-value pairs, TOON represents data using a tokenized notation:

{
  "customer": {
    "name": "Alice",
    "order_id": 5829,
    "items": ["notebook", "pen", "charger"],
    "total_price": 79.50
  }
}
Enter fullscreen mode Exit fullscreen mode

Becomes:

@c{name:"Alice",oid:5829,it:["notebook","pen","charger"],tp:79.5}
Enter fullscreen mode Exit fullscreen mode

This means less text to process, faster serialization, and cleaner logs — perfect for API payloads, automation scripts, and embedded systems.

Why Developers Are Switching to TOON

Unlike many new serialization formats, TOON keeps the simplicity of JSON while cutting down on syntactic noise. It’s especially valuable when you’re:

  • Sending structured data between microservices or agents.
  • Storing large logs or user payloads where size matters.
  • Optimizing workflows in automation platforms such as Make.com or n8n.
  • Embedding data in AI prompt systems where token limits are tight.

In other words: TOON is a developer-friendly evolution of JSON — lighter, faster, and easier to parse.

Convert JSON to TOON in Seconds

The Scalevise JSON to TOON Converter is built for developers who want speed and accuracy without installing packages.

Simply paste your JSON into the editor, click Convert, and your data will instantly appear in valid TOON format.

No registration, no tracking, no API key required — just clean data transformation.

The converter supports:

  • Inline formatting
  • Nested objects and arrays
  • Automatic validation
  • Copy-to-clipboard and local caching

Real-World Example

Let’s say you’re working on a workflow that sends automation logs from Make.com.

Instead of shipping full JSON payloads, you can compress them to TOON to save tokens and improve performance.

JSON:
{
  "workflow": "CRM Sync",
  "status": "completed",
  "steps": ["fetchData", "updateContact", "notifyTeam"]
}

TOON:
@w{wk:"CRM Sync",st:"completed",sp:["fetchData","updateContact","notifyTeam"]}
Enter fullscreen mode Exit fullscreen mode

That’s a 50% reduction in characters, and the structure remains entirely readable.

How It Works Under the Hood

The Scalevise converter is built in Vue 3 with a simple @toon-format/toon integration.

It validates JSON, prevents redundant conversions, and saves your last input/output in local storage for fast reuse.

The entire app runs client-side — meaning your data never leaves your browser.
