How to use query string parser

  1. Paste a query string or complete HTTP(S) URL.
  2. Parse to decode percent escapes and + spaces.
  3. Inspect repeated parameters as arrays in the JSON result.

What to know about the result

  • Parameter names are preserved exactly, including [] suffixes; nested object syntax is not inferred.
  • Empty values remain empty strings. Fragments are excluded, and values are never evaluated.
