Design Tokens Converter

About Design Tokens Converter

Converts design tokens — the colours, spacing, type and shadows a design system is built from — into the formats code uses: CSS custom properties, SCSS, Less, a Tailwind v4 theme, a JavaScript or TypeScript module, or flat JSON.

It reads the W3C Design Tokens Community Group format ($value, $type, $description), which Figma variables exports and Tokens Studio write, and Style Dictionary's older value/type form. Groups nest, a group's $type is inherited by its tokens, and references such as {color.blue.500} are resolved — including references to references — with loops reported rather than followed forever.

Composite tokens become single CSS values: a shadow object becomes a box-shadow value, a font family list becomes a comma-separated stack, a border becomes width, style and colour, and numeric dimensions get px.

Where it helps

• Reads the W3C format and Style Dictionary's, with inherited types.
• Resolves references, including chains, and reports loops and missing targets.
• Turns composite shadow, border and font tokens into real CSS values.
• Writes CSS, SCSS, Less, Tailwind v4, JavaScript, TypeScript or flat JSON.
• Adds an optional prefix and selector, for namespaced or themed variables.

Limits

• It converts one token file at a time; multi-file builds with themes and platforms are Style Dictionary's job.
• Typography composite tokens are written as JSON rather than split into separate font properties.
• Colour values are passed through as written — use the colour converter to change their notation.

Frequently asked questions

Which token format should I use?

The W3C Design Tokens format ($value and $type). It is what Figma variables, Tokens Studio and Style Dictionary v4 all read and write, so tokens in it move between tools without conversion.

How are references resolved?

A value of {group.token} is replaced by that token's value, following chains until it reaches a real value. A reference to a missing token, or one that loops back to itself, stops with an error that names it.

How do I make a dark theme?

Convert your dark tokens with the selector set to [data-theme=dark] (or a media query wrapper), and your light tokens with :root. The variable names match, so components pick up the right values automatically.
