What this tool does
Extract CSS Scope Rules scans pasted CSS as text, lists @scope selectors with source lines, removes duplicate rows, and runs locally in your browser.
Common use cases
Extract CSS @scope root and limit selectors from pasted stylesheets, component CSS, framework output, or copied source before scoped-style audits, architecture review, migration, QA, or documentation handoffs.
Use Extract CSS Scope Rules 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 stylesheets, component CSS, framework output, design-token files, or copied source.
- Choose whether duplicate rows should be removed and whether output should be normalized for comparison.
- Review extracted rows with source lines, then copy the clean list for CSS architecture, migration, QA, or documentation audits.
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
Extract CSS Scope Rules runs locally in your browser. Your pasted CSS is not uploaded, rendered, fetched, crawled, executed, stored, or logged.
