Code converters that run in the tab, not on a server

Code converters, 4 tools.

Pasting code into an online converter means pasting it onto somebody’s server, which is a problem the moment the snippet has a key, a hostname or a customer name in it. These run in the tab.

css-to-tailwindConverts CSS declarations to Tailwind CSS utility classes. Maps standard CSS properties to Tailwind utilities including colors, spacing, typography, layout, borders, and more. Outputs space-separated class strings or @apply blocks.html-to-markdownConverts HTML to Markdown. Handles headings, paragraphs, links, images, lists, code blocks, blockquotes, bold, italic, tables, and more. Strips unsupported attributes with warnings.scss-to-cssFlattens SCSS into plain CSS by resolving nesting, parent selectors (&), variables, mixins, imports, and control directives. Outputs flat selectors with BEM-style expansion for & variants.yaml-to-jsonConvert YAML to JSON. Handles scalars, sequences, mappings, nested structures, comments, quoted strings, and multiline strings (literal | and folded >). No external dependencies - pure Node.js YAML parser.

Enable JavaScript to use the tools. Each one runs inside the tab; nothing here is uploaded.
