How TOML Formatter works (Step-by-Step) 🪄

Step 1: Paste TOML into the editor.
Step 2: The formatter parses the configuration text.
Step 3: Copy the formatted TOML output.

Common Errors

Duplicate keys will fail parsing.
Comments and ordering should be reviewed after formatting.

Large config files can take longer to parse.

Frequently Asked Questions ❓

Does formatting change TOML values?

No. The formatter is intended to preserve values while making spacing and structure easier to read.

Can it fix invalid TOML automatically?

No. Fix syntax errors first, then run the formatter.

Is this different from TOML validation?

Yes. Validation checks whether TOML is valid; formatting rewrites valid TOML into a cleaner style.
