How to use URL Query String Builder

Paste a JSON object. String, numeric, boolean and null values become query parameters; an array creates repeated values under the same name.

Example

`{"tag":["red","blue"],"q":"hello world"}` becomes `tag=red&tag=blue&q=hello+world`.

What to know

Result excludes the leading question mark. Nested objects are rejected, null becomes an empty value, and the tool limits input to 500 keys and 5,000 values.
