Frequently Asked Questions
What are URL query parameters?
Query parameters (or query strings) are a set of key-value pairs attached to the end of a URL, following a question mark (`?`). They are used to pass data from the client to the server. For example, in `?id=123&user=test`, `id` and `user` are the keys.
How does the converter handle duplicate keys?
If the same key appears multiple times in the query string (e.g., `tag=a&tag=b`), our online tool will correctly convert it into a JSON array for that key: `"tag": ["a", "b"]`.
Is this tool safe and secure?
Yes. All parsing and conversion happens in your browser. No data is ever sent to our servers, keeping your URLs and data private. This is a free and secure online utility.
