Are repeated keys supported?

Yes. Each occurrence gets its own row, which is how array-style parameters like tag=a&tag=b are usually expressed.

Do I have to paste a full URL?

No. A bare query string, with or without the leading question mark, works too.

Is encoding handled automatically?

Yes. Values are decoded for editing and re-encoded when the URL is rebuilt.

About the Query String Parser

Long URLs with a dozen tracking and pagination parameters are hard to read. Parsing them into a table makes each key and value obvious, with percent-encoding already decoded.

Edit any row, add or remove parameters and the encoded query string and full URL are rebuilt as you type, so you can copy a corrected link straight into a browser or test.
