Query string parser
Paste a query string or a full URL: every parameter is URL-decoded into a table, duplicate keys are marked, and keys can be sorted or empty values dropped. The tool rebuilds the query string and the full URL live and also shows the parameters as JSON.

How to use
- 1Paste a full URL or just the part after the question mark.
- 2Read the decoded parameters; repeated keys are marked.
- 3Sort the keys or drop empty parameters if needed.
- 4Copy the rebuilt query string, the full URL or the JSON.
They are kept in order and marked. In the JSON view a repeated key becomes an array, for example "id": ["15", "16"].
The query string is rebuilt with standard form encoding, where a space is written as +. When reading, both + and %20 are decoded as a space.
No. Everything is parsed in your browser.
