Q: Does the formatter preserve comments?
A: js-yaml parses semantic content only, so comments are removed on round-trip. If you need comment-preserving formatting, use the raw file in your editor with a YAML LSP instead.
Q: Is my YAML uploaded to your server?
A: No. Parsing and serialization happen entirely in your browser with JavaScript. You can verify by inspecting the Network tab while formatting.
Q: Which YAML version is supported?
A: YAML 1.2 (via js-yaml). This covers virtually every modern config file you will encounter in DevOps and application settings.
Q: What does Minify do?
A: Minify re-emits your YAML in the most compact form while keeping semantic validity. Useful when embedding YAML inside shell scripts or environment variables.
