What this tool does
Extract CSS Clamp Functions scans pasted CSS as text, lists clamp(...) expressions with source lines, removes duplicate rows, and runs locally in your browser.
Common use cases
Extract CSS clamp(...) expressions from pasted stylesheets, component CSS, design-token files, framework output, or copied source before fluid typography, responsive spacing, migration, QA, or documentation audits.
Use Extract CSS Clamp Functions 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, design-token files, framework output, or copied style blocks.
- Choose whether duplicate rows should be removed and whether output should be normalized for comparison.
- Review extracted clamp(...) rows with source lines, then copy the clean list for fluid typography, spacing, 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 Clamp Functions runs locally in your browser. Your pasted CSS is not uploaded, rendered, fetched, crawled, executed, stored, or logged.
