Extract JS Cookie Names scans pasted JavaScript as text, lists cookie names assigned through document.cookie, removes duplicate rows, and runs locally in your browser.
Common use cases
Extract document.cookie assignment names from pasted JavaScript, TypeScript, tag snippets, legacy widgets, tests, or copied source before privacy review, consent QA, migration notes, or release handoffs.
Use Extract JS Cookie 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 JavaScript, TypeScript, tag snippets, legacy widgets, test files, or copied source that may assign document.cookie values.
- Choose whether duplicate rows should be removed and whether extracted text should be normalized for comparison.
- Review extracted cookie names with source-line context, then copy the list for privacy reviews, QA notes, migration tickets, or release 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.
