Extract CSS IDs
Extract CSS ID values from pasted HTML id attributes, JSX snippets, and stylesheet #selectors without rendering or uploading code.
0 / 30,000 characters. No upload, storage, or account required.
CSS ID extraction workflows
Use CSS ID extraction when front-end snippets contain anchors, selectors, test hooks, or legacy IDs that need review before cleanup.
Inventory selectors
Pair this with Extract CSS Classes to review both ID and class naming patterns from pasted code.
Clean repeated output
Send the copied list to Remove Duplicate Lines or Sort Lines for larger audits.
Format before extracting
Use HTML Formatter or CSS Formatter first when pasted snippets are minified.
What this tool does
Extract CSS IDs finds id attributes and #selector IDs in pasted HTML, JSX, and CSS snippets, removes duplicates, shows source-line context, and runs locally in your browser.
Common use cases
Extract CSS ID values from pasted HTML id attributes, JSX snippets, and stylesheet selectors for front-end audits, refactors, anchor review, or test-hook documentation.
Use Extract CSS IDs 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 HTML, JSX, CSS, copied component snippets, or front-end QA notes that contain id attributes or #selectors.
- Choose whether duplicate IDs should be removed and whether output should be normalized to lowercase.
- Review the source-line context, then copy the clean ID list for audits, refactors, tests, or documentation.
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 ID extraction runs locally in your browser. ClearUtils does not upload, store, fetch, crawl, render, or log the code you paste.
FAQ
Does Extract CSS IDs render or upload my code?
No. CSS ID extraction runs locally in your browser and does not upload, store, fetch, crawl, render, or log pasted snippets.
What ID formats can it find?
It finds common HTML id attributes, JSX id strings, and CSS #selectors in pasted markup or stylesheet snippets.
Can it find unused IDs?
No. It extracts IDs from the text you paste. It does not crawl a site, compare files, or audit unused selectors.
