JS String Literals workflows
Use this extractor when copied source needs a browser-local inventory of UI copy, routes, config values, labels, messages, or test strings.
Prepare localization review
Pair user-facing strings with Extract JS Error Messages, Extract JS Route Paths, and Extract JS JSX Prop Names.
Review source constants

What this tool does
Extract JS String Literals scans pasted source as text, lists quoted and template string values with source lines, removes duplicates, and helps review localization copy, route strings, error text, and hard-coded UI messages locally in your browser.
Common use cases
Extract string literal values from pasted JavaScript, TypeScript, JSX, TSX, config modules, tests, localization snippets, generated code, or copied source before copy audits, localization prep, route reviews, migration planning, QA checklists, documentation, or handoffs.
Use Extract JS String Literals 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, config modules, tests, localization snippets, copied source, or generated code that may contain UI copy, routes, error text, or constants.
- Choose whether duplicate rows should be removed and whether extracted values should be normalized for comparison.
- Review extracted string values with line numbers, then copy the clean list for translation prep, hard-coded copy audits, routing reviews, QA checklists, 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 String Literals runs locally in your browser. Your pasted code is not uploaded, compiled, interpolated, resolved, executed, stored, or logged.
Practical notes for this tool
Best use case
Use Extract JS String Literals when a React component, config module, localization file, or test fixture needs a quick inventory of hard-coded UI copy, route strings, error messages, or constants before translation, QA, or cleanup.
Prepare strings for localization review
const title = "Revenue dashboard";
const emptyState = "No invoices found";
throw new Error("No invoices found");Revenue dashboard No invoices found
Privacy and local processing
String-literal extraction runs locally in your browser. ClearUtils does not upload, compile, execute, resolve, store, or log pasted source.
Limitations to know
- It does not know which strings are user-facing.
- Template expressions may need manual review.
- Do not paste live secrets, API keys, tokens, or private customer data into browser utilities.
Practical FAQ
Does this evaluate template strings or run the JavaScript?
No. It scans pasted code as text and extracts literal values. Template expressions, runtime values, imports, and translations still need review in the source project.
