TOML is used by Rust (Cargo), Python (pyproject.toml), and many static site generators. Convert JSON objects to TOML with the JSON Formatter.

How to Convert

Paste JSON into the JSON Formatter and open the TOML tab. Flat or shallow objects convert most reliably.

TOML Limitations

Deeply nested arrays and mixed-type structures may not map cleanly to TOML. Validate output before use in production configs.
