TOML ↔ JSON converter
Convert TOML to JSON and JSON objects back to TOML — locally in your browser.
Output
{
"title": "demo",
"count": 3
}Your data never leaves the browser.
How it works
- Choose TOML → JSON or JSON → TOML.
- Paste your document.
- Copy the result when ready.
FAQ
- Can I convert a JSON array?
- TOML needs an object root — wrap arrays in an object first.
- Is input uploaded?
- No. Conversion stays in your browser.
