Common mistakes in sample input

A full URL is pasted instead of just the raw query string

Fix: Paste only the parameter part or use a full-URL tool if you need URL-aware cleanup.

The user expects percent-decoding

Fix: This tool cleans separators and structure. Use a decoder if you need readable decoded values.

The string contains duplicate keys that should stay

Fix: This tool keeps parameter order and values. It only cleans structure noise.
