What does this tool do?
Decode a query string or URL into ordered key/value entries and a parameter count locally. Inputs: Query string or URL. Outputs: Query parameter list, Parameter count.
How to use it?
Enter query string or url, then choose “Parse”. Copy copies the displayed result or the labeled example/decoded value. Clear removes inputs and results and restores initial options.
Processing is local. Entered URLs are data: they are not visited, uploaded, logged or placed in the route. Generated markup is inert text. Reference lookups use bundled data, and previews are illustrative rather than guaranteed platform output.
URLSearchParams preserves repeated and empty keys/values and treats + as a space. Invalid percent sequences use its standards-based replacement behavior.
