FAQ — Beautify TOML

Beautification

Why did comments disappear?

TOML parse drops # comments — documented limitation.

Minify instead?

Use TOML minifier with removeComments: false to keep # lines when possible.

pyproject.toml?

Same formatter works for Python project metadata — review PEP 621 fields after formatting.

Is my TOML uploaded to a server?

No. Beautification runs entirely in your browser — your TOML never leaves your device and is not stored by FastMinify.

Beautify vs unminify — which should I use?

Beautify formats readable TOML; unminify restores compressed output — try the TOML unminifier. For day-to-day formatting, stay on TOML beautifier.

Can I customize indentation?

Yes — pick 2 or 4 spaces or tabs in the Beautify options toolbar.
