What this tool does

Tracking links and long URLs are easier to inspect when query parameters are decoded and listed line by line.

How to use it well

Start with a small sample, check the output, then paste the full text when the result looks right. For important production data, review the output before saving or sharing it.

Common uses

  • Inspect campaign URLs
  • Debug API query parameters
  • Decode copied links

Questions

Can I paste a full URL?

Yes. The parser accepts a full URL or only the part after the question mark.

What happens with repeated keys?

Repeated keys are shown as separate values.
