Parsing query strings

This tool reads the parameters after the ? in a URL — or a bare query string — and turns them into a tidy JSON object, decoding any percent-encoded characters along the way. Repeated keys (like tags=new&tags=sale) collapse into an array, so nothing is lost. Paste a full link and the domain and fragment are ignored automatically. Parsing happens entirely in your browser.
