About

Decode query parameters from URLs and build query strings from key-value input.

Parsing mode reads a full URL or raw query string and outputs structured JSON, including repeated keys as arrays.

Builder mode accepts one key=value pair per line and generates a properly encoded query string that can be reused in links and requests.

This utility helps when debugging redirects, API links, analytics parameters, and dynamic route generation in frontend applications.
