FAQ
Does YAML formatting change data?
No. Only whitespace and indentation change—the parsed data structure stays the same.
Can bad indentation be auto-fixed?
Invalid YAML shows parse errors. When syntax is valid, inconsistent indentation is normalized on format.
Is my config uploaded?
No. Formatting runs locally in your browser.
