FAQ
- Why query is not applied: ensure key is not empty and base URL is valid.
- Why open URL fails: popup may be blocked or generated URL is empty.
- Why parser returns empty: make sure the input URL contains query string after ?.
- Will data be uploaded: no, all parsing and generation run locally in browser.
