Parses, validates, and reformats config files. TOML, INI, HCL, Caddyfile, and Nginx use the formatter tab (Nginx also lints for common errors); Docker Compose and GitHub Actions use the linter tab (GitHub Actions also has a form-based workflow builder); .htaccess and Helm inspect/generate from options. For TOML ↔ YAML conversion, see YAML Tools' dedicated tab.
