Fix: Fix malformed sections, keys, arrays, or values before expecting clean formatted output.
Fix: Formatting focuses on normalized readable output, not perfect preservation of every original style choice.
Fix: Use TOML Validator when correctness matters more than presentation.
A TOML formatter makes TOML easier to read by normalizing spacing, assignments, arrays, and section layout.
TOML Formatter focuses on readability, while TOML Validator focuses on whether the TOML is valid.
No. Invalid TOML still needs to be corrected before it can be formatted reliably.
Yes. Sections, keys, and arrays are common TOML formatting use cases.
Use TOML to JSON when you want to transform TOML into JSON rather than keep it as TOML.
