Extract data-* attributes from pasted HTML, JSX output, and component snippets for analytics, QA, and migration review.
0 / 30,000 characters. No upload, storage, or account required.
Data attribute extraction workflows
Use data attribute extraction when QA hooks, analytics labels, component metadata, or migration identifiers are hidden inside pasted markup.
Document test hooks
Pair this with Extract CSS IDs and Extract CSS Classes when reviewing front-end selectors.
Inspect markup first
Use HTML Formatter before extraction when copied snippets are minified or difficult to scan.
Clean the final list
Send copied rows to Remove Duplicate Lines, Filter Lines, or Sort Lines.
What this tool does
Extract Data Attributes finds data-* attribute names and values in pasted HTML snippets, removes duplicates, shows source-line context, and runs locally in your browser.
Common use cases
Extract data-* attribute names and values from pasted HTML, component output, analytics snippets, QA fixtures, and copied source fragments before tests or migration documentation.
Use Extract Data Attributes 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 snippets, test fixtures, component output, analytics markup, or copied source fragments that contain data-* attributes.
- Choose whether duplicate name/value pairs should be removed and whether attribute names should be normalized to lowercase.
- Review the extracted data attributes with source lines, then copy the clean list for QA, tests, analytics notes, or migration 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
Data attribute extraction runs locally in your browser. ClearUtils does not upload, store, fetch, crawl, render, execute, or log the HTML text you paste.
FAQ
Does Extract Data Attributes execute my code?
No. It reads pasted text only and extracts data-* attributes. It does not render, execute, fetch, crawl, upload, store, or log snippets.
What data attributes can it find?
It finds common data-* attributes with quoted or unquoted values, including data-testid, data-id, data-track-event, and similar markup labels.
Can I use this for analytics or QA hooks?
Yes. It is useful for inventorying tracking labels, test IDs, component metadata, and migration identifiers from small pasted snippets.
