Extract JS String Literals
Extract string literal values from pasted JavaScript, TypeScript, JSX, or TSX source without executing, compiling, interpolating, resolving, or uploading code.
0 / 30,000 characters. No upload, storage, or account required.
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.
Audit user-facing copy
Pair it with Extract JS Error Messages, Extract JS Route Paths, and Extract JS JSX Prop Names.
Review source constants
Use Extract JS Regex Literals, Extract JS Numeric Literals, and Extract JS Variable Names.
Clean copied output
Send extracted rows to Sort Lines, Remove Duplicate Lines, or Normalize Whitespace.
What this tool does
Extract JS String Literals scans pasted source as text, lists quoted and template string literal values with source lines, removes duplicates, and runs 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 string literals.
- 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 localization, content audits, migration notes, 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.
