Two free browser tools now qualify for Google's rich results: YAML to JSON Converter and CSS Formatter.
Both have full structured data: SoftwareApplication, FAQPage, HowTo, and BreadcrumbList. That's what generates the Q&A panels and step-by-step guides you see above the regular search result link.
What each tool does
YAML to JSON: paste your config, get JSON output. Handles multi-document YAML (the --- separator), Kubernetes manifests, Ansible playbooks, Helm charts. Server-side processing, nothing stored.
CSS Formatter: format, beautify, minify, and validate CSS in one place. Syntax errors report line and column numbers.
Both are free. No signup. No install required.
