0 / 30,000 characters. No upload, storage, or account required.
Common CSS class extraction workflows
Use CSS class extraction when you need a quick inventory of classes in copied markup, templates, components, or small stylesheets.
Format first
Use HTML Formatter before extracting classes from minified markup or long one-line templates.
Find color tokens too
Use Extract HEX Colors when front-end snippets also contain color codes that need review.
Clean the inventory
Use Sort Lines and Remove Duplicate Lines after extraction for a stable class inventory.
What this tool does
Extract CSS Classes finds class attribute values and dot-class selectors, removes duplicates, shows source-line context, and runs locally in your browser.
Common use cases
Extract CSS class names from pasted HTML, JSX className attributes, Tailwind snippets, and stylesheet selectors for quick front-end inventory or cleanup.
Use Extract CSS Classes when you are working with copied API payloads, logs, encoded values, config snippets, identifiers, or debugging data and need a quick browser-local check before pasting the result into docs, tickets, tests, or another developer tool.
How to use it
- Paste HTML, JSX, Tailwind utility snippets, CSS selectors, or component fragments that contain class names.
- Choose whether duplicate class names should be removed and whether class names should be lowercased for rough inventory review.
- Review the extracted class list and source lines, then copy the clean one-class-per-line output.
Example workflow
Copy a small payload or encoded value from an API response, request URL, log line, or config file. Run the focused check here, confirm the output is readable, then continue with related developer data tools such as validation, formatting, decoding, timestamp conversion, or CSV/JSON conversion.
Privacy note
CSS class extraction runs locally in your browser. ClearUtils does not upload, store, fetch, crawl, render, or log the code snippets you paste.
FAQ
Does Extract CSS Classes render or upload my code?
No. CSS class extraction runs locally in your browser and does not upload, store, fetch, crawl, render, or log pasted snippets.
What class formats can it find?
It finds common HTML class attributes, JSX className strings, and dot-class selectors in small pasted CSS or component snippets.
Can it audit unused CSS?
No. It only extracts class names from the text you paste. It does not crawl pages, inspect a full bundle, or compare usage across files.
