YAML, JSON, and TOML
Convert or check a document in the browser. The text is not uploaded.

Parsing stays in this browser. Input is not uploaded or saved.
How to use the toolkit
- Choose a direction. Each one loads its own sample, options, and editor languages.
- Paste configuration or use Sample. The result updates after you pause typing.
- Read the status before you copy or download. A failed parse does not produce a file.
What stays on this machine
Parsing, validation, and formatting run in the browser. Editor text is not written to local storage or the URL. See the privacy policy for what a normal page request still includes.
FAQ
- Which page should I open?
- Stay here to switch direction, or open a dedicated tool when you want instructions for that conversion. Each tool keeps its own sample and options.
- Do you store what I paste?
- No. Editor contents are not uploaded, saved in browser storage, or put in the page URL.
- Will invalid input be auto-corrected?
- No. A failed parse leaves the output empty and shows the parser message. The YAML validator also leaves the input text untouched.
