Frequently Asked Questions

TOML strengths?

Explicit tables, typed values, comments preserved — Cargo and Python packaging standardized here. Obvious key-value beats clever nesting.

Tables vs nesting?

[table] headers map to nested objects; arrays-of-tables ([[products]]) repeat blocks. Convert with structure intact.

Comments survive?

No — like most format conversions, comments drop. Keep documented masters; convert working copies.

Do TOML configs upload?

No — parsing runs locally in your browser. Configs never leave your device.
