Your StyleX tokens appear here

Add a theme, select its format, and generate ready-to-download StyleX files.

Local and safe conversion

The converter runs in your browser. It reads static data and never executes uploaded JavaScript or TypeScript.

How to Convert Tailwind to StyleX

  1. 1

    Add Your Theme Source

    Paste Tailwind CSS v4 @theme variables, upload a token JSON file, or add the static theme object from a Tailwind config.
  2. 2

    Select or Detect the Format

    Keep automatic detection for most files, or select CSS, JSON, or static config when the source is ambiguous.
  3. 3

    Generate the Token Modules

    The converter groups supported values into StyleX constants. It warns about unresolved variables and stops on dynamic config expressions.
  4. 4

    Download and Import

    Download tokens.stylex.js and its TypeScript declaration file. Import only the token groups that your components use.

Common Use Cases

1

Incremental Tailwind Migration

Keep established design values while new components move to StyleX one group at a time.
2

Shared Design Tokens

Convert a neutral JSON token file into typed StyleX groups for React applications and component libraries.
3

Tailwind v4 Theme Export

Turn @theme CSS variables into JavaScript constants without copying every value by hand.
4

Migration Review

Use the generated groups, warnings, and parser errors to find values that need manual review.

Why Convert Tailwind Tokens to StyleX?

A shared token layer keeps colors, spacing, typography, radii, shadows, and breakpoints consistent during a Tailwind-to-StyleX migration. This converter turns the source theme into named StyleX constants without executing the uploaded config.

The Tailwind to StyleX Converter creates reusable StyleX design-token modules from Tailwind CSS v4 theme variables, CSS custom properties, design-token JSON, and static Tailwind theme objects. It generates a tokens.stylex.js file with stylex.defineConsts() groups and a matching TypeScript declaration file.

The output separates colors, spacing, fonts, font sizes, font weights, radii, shadows, breakpoints, transitions, and other supported values. Simple CSS variable aliases resolve automatically. A base Tailwind spacing value can also produce the standard spacing scale. The converter warns about unresolved references and stops on unsupported dynamic values.

The conversion runs in your browser. Uploaded JavaScript and TypeScript are treated as static text. The tool parses supported theme data and does not execute config files, plugins, functions, or template expressions.

How It Compares

The tailwind-stylex package publishes StyleX constants for Tailwind's default design tokens. This converter serves a different need: it converts your custom Tailwind theme or design-token file into compatible StyleX constant groups.

Build-time migration scripts can handle more complex JavaScript, but they must execute project code. This browser converter uses a static parser instead. That choice supports quick review and safer handling of unknown config files, with clear warnings for values that require manual work.

Tips for a Reliable Conversion

1
Use semantic names such as --color-action and --radius-card when the tokens describe product roles.
2
Keep automatic detection for complete files. Select a format when you paste only an object fragment.
3
Review every warning before you replace an existing Tailwind theme.
4
Dynamic JavaScript functions and plugin calls need manual migration because the converter never executes uploaded code.
5
Keep the original theme in version control until visual review confirms the migration.

Frequently Asked Questions

1

What input formats does the converter support?

It supports Tailwind CSS v4 @theme variables, ordinary CSS custom properties, JSON token objects, and static theme objects from JavaScript or TypeScript Tailwind configs.
2

Does the converter execute my Tailwind config?

No. It reads the file as text and parses supported static values. It rejects dynamic references, functions, plugin calls, and template expressions.
3

What files can I download?

You can download tokens.stylex.js and tokens.stylex.d.ts. The first file contains StyleX constants. The second provides TypeScript declarations.
4

Does it support Tailwind CSS v4 @theme variables?

Yes. It maps Tailwind theme namespaces such as color, spacing, font, text, radius, shadow, and breakpoint into named StyleX groups.
5

Can it convert a custom design-token JSON file?

Yes. It accepts nested JSON objects, Tailwind-style theme and extend objects, and token values stored under a $value property.
6

How are CSS variable aliases handled?

The converter resolves simple var(--token-name) references when the referenced token exists in the same source. It reports unresolved references as warnings.
7

Is this an official tailwind-stylex tool?

No. FindUtils is not affiliated with the tailwind-stylex project. The generated constants follow a compatible StyleX token structure.
8

What needs manual review after conversion?

Review dynamic config logic, plugin-generated values, keyframes, complex breakpoint objects, and any unresolved CSS variables. The converter reports these cases when it can identify them.
