CSS attribute selector extraction workflows
Use this extractor when pasted styles need a browser-local inventory of ARIA, data-state, type, href, and other attribute selector patterns before cleanup or QA.
Audit state selectors
Pair attribute selectors with Extract CSS Pseudo-Classes, Extract CSS Selectors, and Extract CSS Property Names.
Review accessibility hooks
Use Extract ARIA Labels, Extract Form Field Names, and CSS Formatter while documenting UI states.
Clean copied output
Send extracted rows to Remove Duplicate Lines, Sort Lines, or Normalize Whitespace.
What this tool does
Extract CSS Attribute Selectors scans pasted CSS selectors as text, lists attribute selectors with source lines, removes duplicate rows, and runs locally in your browser.
Common use cases
Extract CSS attribute selectors such as [aria-expanded], [data-state="open"], [type="button"], and [href^="https"] from pasted stylesheets, component CSS, framework output, or copied source before accessibility, state, data-attribute, migration, or documentation audits.
Use Extract CSS Attribute Selectors 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 CSS selectors, component styles, framework output, or copied stylesheet source that contains attribute selectors.
- Choose whether duplicate attribute selector rows should be removed and whether output should be normalized for comparison.
- Review extracted attribute selectors with source lines, then copy the clean list for accessibility, state, data-attribute, or migration 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 Attribute Selectors runs locally in your browser. Your pasted CSS is not uploaded, rendered, fetched, crawled, executed, stored, or logged.
