TOML Diff FAQ

Is TOML Diff a text diff or a structural diff?

It is structural. Both inputs are parsed as TOML first, then the resulting data is compared by keys, arrays, and values.

Can I compare invalid TOML documents?

No. Both inputs must be valid TOML. If either side fails to parse, the tool will indicate which side is invalid.
