Why convert TOML to JSON?

TOML powers Rust's Cargo.toml, Python's pyproject.toml and many Go and Hugo projects. Converting to JSON makes that configuration readable by scripts and tooling that only speak JSON.

Are my TOML files uploaded anywhere?

No. The conversion runs inside your browser using your own device's processing power, so the file never leaves your computer or phone and nothing is stored on a server.
