Why convert JSON to TOML?
Moving a project's settings into a Rust, Python or Hugo toolchain usually means producing TOML. This writes your JSON structure out as a valid TOML settings file.
Why does my JSON fail to convert?
TOML needs a set of named settings at the top level. A JSON file that starts with a list rather than an object can't be represented, so wrap it in an object first.
Are my JSON 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.
