Extract design tokensFreeFor designers and developers

45 min

saved on a typical run. Our estimate, against extracting tokens from a stylesheet by hand into a spreadsheet.

Before: what you give it

The example input, as typed in. You paste text, CSS, markup or notes.

:root {
  --ink: #1a1a1a;
  --paper: #fafaf7;
  --accent: #e4572e;
  --accent-hover: var(--accent);
  --space-2: 8px;
  --radius: 6px;
  --font-body: "Source Serif 4", Georgia, serif;
  --ease: cubic-bezier(0.2, 0, 0, 1);
}
@media (prefers-color-scheme: dark) { :root { --ink: #f2f2ee; --paper: #141414; } }
body { font: 400 17px/1.55 var(--font-body); color: var(--ink); background: var(--paper); }
h1 { font-size: 48px; line-height: 1.05; margin: 0 0 24px; }
h2 { font-size: 30px; margin: 32px 0 12px; }
small { font-size: 13px; }
...

After: what comes back

The first lines of a real run on that input. Nothing here is edited by hand.

# Design tokens

13 rules, 38 declarations, 8 custom properties. Root font size 16px (used to convert rem).

## Colours (6 distinct, 8 uses)

| Value | Uses | Where |
|---|---|---|
| #1a1a1a | 2 | text 1, border 1 |
| #e4572e | 2 | background 1, text 1 |
| #0000001f | 1 | shadow 1 |
| #c9441f | 1 | background 1 |
| #fafaf7 | 1 | background 1 |
| #ffffff | 1 | text 1 |
... full output on the tool page

What you get

Token tables grouped by type with use counts and locations, light and dark values, and W3C token JSON

What it cannot do

Reads CSS only; pasted CSS is free, fetching a live URL needs Pro, and nothing is rendered.

Try it here

The form starts with the same example input, so you can run it first and then swap in your own.
