What this tool does

URL Query Params Extractor parses one URL per line and turns query strings into a readable table. It accepts full URLs, bare domains, relative paths, and question-mark-only query strings, then lists each parameter key, value, source line, source URL, and repeat count. Turn on deduplication to merge identical key/value pairs across many URLs, copy the result as CSV, or export it for spreadsheet review. It is useful for UTM audits, analytics QA, API debugging, redirect checks, and comparing campaign links. All parsing stays in the browser.

How URL Query Params Extractor fits into your work

Use it in the small gaps between coding, reviewing, debugging, and shipping.

Developer jobs

  • Formatting, validating, shrinking, or inspecting code-adjacent text.
  • Preparing snippets for documentation, tickets, commits, or handoff.
  • Checking a small payload quickly without switching tools.

Developer checks

  • Run irreversible transforms like minify or obfuscate on a copy.
  • Keep secrets out of pasted snippets unless the tool explicitly stays local.
  • Use your normal tests or linter before shipping transformed code.

Real-world use cases

  • Audit a batch of campaign URLs before launch

    Paste every campaign link, dedupe parameters, and export the CSV. You can quickly spot inconsistent UTM source, campaign, or medium values before traffic starts.

  • Debug API links copied from logs

    Paste URLs from logs or browser history to inspect query keys and values line by line. Invalid lines are surfaced so malformed input does not disappear unnoticed.

Common pitfalls

  • Deduping by key/value hides which URL came first; check source lines when debugging one specific link.

  • Query parameters can contain personal data, so review values before sharing exported CSV files.

Privacy

Parsing runs locally and URLs are not uploaded. Exported CSV files and shared URL state may still contain sensitive query values, so review them before sending.
