How JSON ↔ TOML works

Convert JSON objects to TOML and TOML configs back to JSON for Cargo, Pyproject, and app settings. Runs locally in your browser.

  1. 1. Add input. Paste, type, or upload. Use a sample if you just want to see it work.
  2. 2. Run it. Processing happens in the browser.
  3. 3. Copy or download. Take the output and close the tab.
  • JSON to TOML
Can the root value be an array?
No. TOML requires an object root, so JSON arrays and primitives are rejected.

ToolBay does not store your input. Close the tab and it is gone. More developer tools.
