Does it handle array values?

Yes. If a JSON key has an array value such as ["js","ts"], it is expanded into repeated parameters: tag=js&tag=ts.

Are special characters encoded?

Yes. All values are percent-encoded using URLSearchParams, making the output safe for direct use in URLs.

What about nested objects?

Nested objects are not supported. Convert your JSON to a flat key-value structure first. Nested values will be serialized using their toString() representation.

Object to Query String takes a flat or shallow JSON object and encodes it as a URL query string. Array values are expanded into repeated keys (e.g. tag=js&tag=ts). All values are percent-encoded so the output is safe to append to any URL. Ideal for building API request URLs, debugging HTTP clients, and constructing links programmatically.
