TOML Validator FAQ
What TOML issues does the validator catch?
It catches parsing errors such as malformed strings, invalid table syntax, broken arrays, and other TOML syntax issues reported by the parser.
Does the TOML validator support schemas?
No. It only validates TOML syntax. It is meant to confirm that a document can be cleanly parsed before you format, convert, or compare it.
