CSS property name extraction workflows
Use this extractor when pasted styles need a browser-local inventory of declaration properties before refactoring, migration, QA, or documentation.
Audit CSS declarations
Pair property names with Extract CSS Selectors, Extract CSS Important Declarations, and CSS Formatter.
Review design-system usage
Use Extract CSS Variables, Extract CSS Colors, and Extract CSS Z-Index Values while documenting stylesheet patterns.
Clean copied output
Send copied rows to Remove Duplicate Lines, Sort Lines, or Normalize Whitespace.
What this tool does
Extract CSS Property Names finds declaration property names such as color, margin-inline, and --custom-properties in pasted CSS, removes duplicates, shows source lines, and runs locally in your browser.
Common use cases
Extract CSS declaration property names from pasted stylesheets, component styles, theme files, or copied style blocks before browser-support checks, refactors, migration, QA, or documentation cleanup.
Use Extract CSS Property Names 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, style tags, component styles, theme files, or copied source that contains property declarations.
- Choose whether duplicate property rows should be removed and whether output should be normalized for comparison.
- Review extracted property names with source lines, then copy the clean list for CSS audits, browser support checks, migration, or documentation handoffs.
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 property name extraction runs locally in your browser. Your pasted CSS is not uploaded, rendered, fetched, crawled, executed, stored, or logged.
