Minified bundles from production, copied theme snippets, and legacy stylesheets are easier to audit once indented. Doing that locally keeps brand colours and internal class names off a third-party server.
js-beautify runs with indent_size 4 on the text you provide. It does not resolve @import, expand variables, or run autoprefixer.
No Sass/Less/SCSS nesting, no Tailwind class sorting, no stylelint. Invalid CSS may format with surprising breaks — fix syntax in your editor.
That is the promise behind every tool here. Files are read in your browser tab, processed there, and discarded when you close it — never uploaded to our servers.
