Overview

What is Query String Parser?

URLs often carry significant amounts of data in their query strings, which can become messy and unreadable when encoded. Our parser takes any query string or full URL and breaks it down into a key-value list (JSON), making it easy to see exactly what parameters are being passed to a server.
