Why convert JSON to a query string?
When you need to build a URL from structured data, turning a JSON object into a properly encoded query string by hand is fiddly. Paste a flat JSON object above and get a ready-to-use query string in an instant.
How it works
The converter encodes each key and value of your flat JSON object into a URL query string. An array of scalar values is expanded into repeated keys, while a nested object stops it with a clear error since it cannot be represented unambiguously, and a null becomes an empty value. As the inverse of the Query String to JSON tool, it completes the round trip, and because it runs locally your data never leaves your device.
