Frequently asked questions.

Does the formatter change values?

No. It only normalises whitespace and indentation. The parsed values are unchanged.

Will it change my quoting style?

No. Strings are emitted with the same quoting that js-yaml determines is canonical.

Is my YAML uploaded?

No. Formatting happens entirely in your browser.
