About Query String Builder
Query String Builder converts one key=value or key:value pair per line into URL-encoded parameters using URLSearchParams. Use it to prepare a query component for an API or link when keys and values are already defined. Repeated keys are overwritten because the tool uses set(), and colons or equals signs inside values can be interpreted unexpectedly. It does not attach a base URL or validate parameter meaning. Building happens in the browser; avoid secrets and personal data in URLs.
