Input (TOML)
Output (JSON)
Everything runs in your browser. No upload, no sign-up.
How it works
STEP 1
Pick a direction
Choose TOML → JSON or JSON → TOML. The input and output labels update to match.
STEP 2
Paste your text
Drop in a config file or an API response. It is parsed right in your browser — nothing leaves your device.
STEP 3
Copy the result
Get clean, pretty output and copy it with one click. A friendly message points to any parse problem.
