YAML to TOON Runs in your browser. No input data is sent to our server.

Paste YAML into the editor to generate TOON instantly, compare token estimates, and review whether the structure is a good fit for compact AI payloads. This is helpful for config-like data, repeated rows, and structured prompt context.

Paste content into the yaml input panel.

2

Run the tool to generate TOON output and compare the token analysis.

3

Copy or download the TOON output and the analysis summary after you review the token comparison and suitability score.

What this tool helps you do

Convert YAML into TOON directly in the browser

Compare approximate token counts for the source input, normalized JSON, and TOON

See whether the structure is a strong TOON candidate

Copy the encoded result for prompt and payload experiments

Why this helps in AI workflows

You have YAML config or structured records and want a compact AI-friendly representation.

A prompt workflow uses repeated structured objects and YAML feels too verbose.

You want to compare approximate token impact before switching formats in an LLM pipeline.

You need to test TOON quickly without building a local conversion script.

Which tool should you choose?

YAML to TOON: Choose this when your structured source content starts as YAML and you want to compare TOON compactness for AI use.

JSON to TOON: Choose the JSON version when your source data is already JSON or an API response.

Common problems and fixes

My YAML is easy to edit but feels bulky when I reuse it in AI prompts.

Convert it to TOON and compare the approximate token difference before changing your workflow.

I want to know whether a YAML structure is worth normalizing for compact AI transport.

Run the converter and inspect the analysis summary, TOON suitability score, and encoded output together.

Frequently asked questions

Why convert YAML to TOON?

YAML is human-friendly, but TOON can be more compact for machine-facing AI workflows. This tool helps you compare the difference quickly.

Does this support normal YAML mappings and arrays?

Yes. The converter parses standard YAML into structured data first, then encodes that data as TOON.

Can TOON save tokens compared with YAML?

Sometimes, especially with repeated arrays of objects or structured records. The tool shows an approximate comparison so you can judge the tradeoff.

What if my YAML is invalid?

The tool validates and parses the YAML first. If the input cannot be parsed, it returns a clear error instead of invalid TOON.
