0 / 30,000 characters. No upload, storage, or account required.
CSS font-weight extraction workflows
Use this extractor when pasted styles need a browser-local inventory of weight values before typography cleanup, font loading review, migration, QA, or documentation.
Audit font weight usage
Pair font-weight rows with Extract CSS Font Families, Extract CSS Font Sizes, and Extract CSS Font Faces.
Review design-system tokens
Use Extract CSS Variables, Extract CSS Property Names, and CSS Formatter while documenting typography tokens.
Clean copied output
Send extracted rows to Remove Duplicate Lines, Sort Lines, or Normalize Whitespace.
What this tool does
Extract CSS Font Weights finds font-weight declaration values such as normal, bold, numeric weights, and token variables in pasted CSS, removes duplicate rows, shows source lines, and runs locally in your browser.
Common use cases
Extract font-weight declaration values from pasted CSS, style blocks, component styles, theme files, or copied source before typography audits, font loading review, migration, QA, or documentation cleanup.
Use Extract CSS Font Weights 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 font-weight declarations.
- Choose whether duplicate weight rows should be removed and whether output should be normalized for comparison.
- Review extracted font-weight rows with source lines, then copy the clean list for typography audits, QA, migration notes, 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 font-weight extraction runs locally in your browser. Your pasted CSS is not uploaded, rendered, fetched, crawled, executed, stored, or logged.
