Convert between JSON and query string
A URL's parameters, that query string in the ?a=1&b=2 format, and a JSON object hold the same information in different clothing. You go back and forth between the two constantly in web development, and this converter translates in both directions.
Take a flat JSON object and turn it into a query string already fit for the URL, or do the opposite and parse the parameters back into an object. It even tackles arrays in the a[]=1&a[]=2 style, exactly the kind of detail that gives you a headache by hand. Good for building links, debugging requests or reading a URL's parameters.
It all runs in the browser, with nothing sent out. Paste the JSON or the query string and grab the equivalent format, ready to use.
