JSON to Query String Converter

Turn a JSON object into a URL query string. Nested objects and arrays are written with bracket keys, the style that PHP and the qs library read.

Example

Input
{
  "q": "json to yaml",
  "page": 2,
  "filters": { "lang": ["en", "de"], "sort": "recent" }
}
Output
q=json%20to%20yaml&page=2&filters%5Blang%5D%5B0%5D=en&filters%5Blang%5D%5B1%5D=de&filters%5Bsort%5D=recent
