How do I convert a JS file to LESS using your tool?

Upload your JavaScript file containing object definitions. The converter parses it and outputs a LESS file with variables. For example, `{ theme: { color: '#fff' } }` becomes `@theme-color: #fff;`. Download the result instantly.

Why would I convert JavaScript to LESS instead of using JSON directly?

LESS variables integrate directly into CSS preprocessor workflows. Converting JS object data to LESS lets you use design tokens in stylesheet context without runtime JS. It reduces duplication and enables build-time compilation.

How does the conversion handle nested objects, arrays, and comments?

Nested objects are flattened into scoped variable names using hyphens (e.g., `a.b`→`@a-b`). Arrays become comma-separated lists, and boolean/numeric types are preserved. Comments in JS are retained as LESS comments.

Is JS-TO-LESS free to use?

Yes, JS-TO-LESS on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?

Does this converter work on mobile phones and tablets?

Yes! JS-TO-LESS works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.

Is there any software installation required?

No software or browser extension installation is needed. All conversions are performed directly online.
