TOML Formatter
Attempt to pretty-print TOML-like config data — works well for JSON-shaped input, falls back to basic brace cleanup for real TOML syntax.
How to Use TOML Formatter
- 1Paste your config data
- 2Click Process
- 3Review the output — JSON-shaped input pretty-prints correctly; real TOML syntax falls back to basic cleanup only
Frequently Asked Questions
No — it first tries to parse your input as JSON; if that succeeds, it pretty-prints it as JSON. If it fails (which real TOML syntax will, since TOML isn't JSON), it falls back to a generic brace-based cleanup — it does not have a real TOML parser.
Since genuine TOML (key = value pairs, [section] headers) isn't valid JSON, this tool will use its fallback brace-cleanup pass, which won't correctly reformat TOML's actual syntax rules.
A dedicated TOML linter/formatter such as Taplo, or your IDE's TOML extension, will correctly parse and format real TOML files.
Yes — both tools share the identical try-JSON-then-fallback logic; only the tool name and framing differ.
