About this tool: Query String Converter
Convert URL query parameters to JSON and back while preserving repeated parameter values.
Repeated parameters become arrays, so tag=a&tag=b is preserved instead of silently keeping only the last value. Building accepts an object containing scalar values or arrays of scalars. Spaces use the standard form-encoding plus sign; a literal plus is percent-encoded.
