URL-decode a List

Decode lists of URL-encoded text values using the URL-decode a List Tool.

Automatically trims whitespace, skips blank lines, and shows invalid encodings clearly. Features include copy/export options, file import for safe text types, and live update with output counter. Ideal for transforming encoded web parameters, API data, or form inputs back into readable strings.

Useful Tools & Suggestions:

If you’re URL-decoding a list, it’s a good idea to run Trim List Items afterward to clean up any trailing characters or spacing that might’ve been hiding in the encoded values. Then, if you’re prepping the results for another round of processing, Normalize List Item Separators helps keep everything consistent and readable. That combo keeps your list clean, accurate, and way easier to work with.
