Do I need to include the full URL?

No. You can paste just the query string portion (e.g. foo=bar&name=John%20Doe), with or without a leading ?. Full URLs are also accepted — the tool will extract the query string automatically.

What is the difference between the raw and decoded value columns?

The raw value column shows the value exactly as it appears in the query string, including percent-encoding (e.g. John%20Doe). The decoded column shows the human-readable result after URL decoding (e.g. John Doe).

Does it handle repeated parameter keys?

Yes. URLSearchParams supports multiple values for the same key. Each key-value pair is shown as a separate row in the table.

Paste a URL query string (with or without the leading ?) and this tool parses it using URLSearchParams, showing each parameter as a row with its key, raw encoded value, and decoded value side by side. Useful for inspecting complex query strings from API calls, analytics URLs, or form submissions.
