Extract JS Storage Keys
Extract localStorage and sessionStorage key strings from pasted JavaScript, TypeScript, JSX, or TSX source without executing, rendering, fetching, compiling, or uploading code.
0 / 30,000 characters. No upload, storage, or account required.
JS Storage Keys workflows
Use this extractor when copied source needs a browser-local inventory before API reviews, release QA, migrations, documentation, cleanup, or handoffs.
Review browser persistence
Pair storage keys with Extract JS Module Specifiers, Extract JS Environment Variables, and Extract JS Route Paths.
Review behavior and failures
Use Extract JS Error Messages, Extract JS Function Names, and Extract JS Test Case Names.
Clean copied output
Send extracted rows to Sort Lines, Remove Duplicate Lines, or Normalize Whitespace.
Quick answer
Extract JS Storage Keys is a browser-based extract JS storage keys for checking copied developer data such as payloads, URLs, encoded values, identifiers, snippets, or logs without sending the input to a server.

What this tool does
Extract JS Storage Keys scans pasted source as text, lists localStorage and sessionStorage key names with source lines, and helps review browser persistence, checkout migrations, privacy cleanup, and stale key removal locally in your browser.
Common use cases
Extract localStorage and sessionStorage key strings from pasted JavaScript, TypeScript, frontend components, browser utilities, tests, or copied source before client-state audits, privacy reviews, migrations, documentation, or QA handoffs.
Use Extract JS Storage Keys 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, JSX, TSX, client modules, persistence helpers, tests, generated code, or copied source that may read, write, or remove browser storage keys.
- Choose whether duplicate rows should be removed and whether extracted values should be normalized for comparison.
- Review extracted storage keys with line numbers, then copy the clean list for migration notes, privacy reviews, QA reset checklists, stale-key cleanup, documentation, or 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
Extract JS Storage Keys runs locally in your browser. Your pasted code is not uploaded, compiled, resolved, fetched, executed, stored, or logged.
Practical notes for this tool
Best use case
Use Extract JS Storage Keys when browser persistence code needs a quick inventory of localStorage and sessionStorage keys before privacy review, checkout migration, stale-key cleanup, or QA reset planning.
Review checkout storage keys before renaming
localStorage.setItem("cart:id", cartId);
const theme = localStorage.getItem("theme");
sessionStorage.removeItem("checkout-step");cart:id theme checkout-step
Privacy and local processing
Storage-key extraction runs locally in your browser. ClearUtils does not read your browser storage, upload source, execute code, store snippets, or log keys.
Limitations to know
- It may miss keys built dynamically from variables.
- It does not classify whether a key contains sensitive data.
- Privacy and retention reviews still need source context and product policy checks.
Practical FAQ
Does this read my browser storage?
No. It only scans pasted source text for storage key strings. It does not access your actual localStorage, sessionStorage, cookies, or browser profile.
