What this tool does

Extract JS DOM Selectors scans pasted JavaScript as text, lists selector strings used in common DOM lookup calls, dedupes repeated selectors, and runs locally in your browser.

Common use cases

Extract DOM selector strings from pasted JavaScript, TypeScript, browser snippets, tests, or component source before selector audits, UI migration, QA fixture cleanup, or documentation handoffs.

Use Extract JS DOM Selectors 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.

Debug a copied sampleUse a sanitized payload, URL, config value, identifier, stylesheet, markup snippet, or log excerpt when you need a fast check before opening a heavier IDE, schema, or API client.
Prepare a handoff noteTurn messy developer data into a clearer example for tickets, documentation, code review comments, test fixtures, or support notes without exposing secrets.
Chain a safe transformationMove to a related formatter, validator, encoder, decoder, converter, or generator only after the current output still needs another compatible developer-data step.

How to use it

  1. Paste JavaScript, TypeScript, browser snippets, component source, test files, or copied code that contains the target pattern.
  2. Choose whether duplicate rows should be removed and whether extracted text should be normalized for comparison.
  3. Review extracted rows with source-line context, then copy the clean list for audits, migration notes, QA, documentation, 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.

Privacy note

This extractor runs locally in your browser. Your pasted code is not uploaded, executed, rendered, fetched, bundled, stored, or logged.
