Why Convert URL Parameters to JSON?
URL parameters are a common way to pass data in web applications, but they can be difficult to read and work with. Converting them to JSON makes the data structured, readable, and easy to use in your code or APIs.
Frequently Asked Questions
What formats are supported?
You can input a full URL with parameters, just the query string with or without the leading ?, or even parameters with array notation like ids[]=1&ids[]=2.
How are array parameters handled?
When the same parameter appears multiple times (like tags=a&tags=b), they are automatically combined into a JSON array. Array notation with brackets is also supported.
Are encoded values decoded?
Yes, URL-encoded values (like %20 for space or %2F for /) are automatically decoded to their original characters in the JSON output.
What happens to the URL path?
Only the query string portion (after the ?) is parsed. The base URL, path, and fragment (after #) are ignored.
Is my data secure?
Yes, all processing happens locally in your browser. Your URLs and parameters are never sent to any server.
