When you need to convert a PDF to Microsoft Excel, you're usually limited to just a few per day or even month with free tools. The only way to bypass this restriction is to pay for a premium version or use your desired tool in different browsers.
For instance, if you need to convert four PDFs to Excel, you could convert two in Chrome and two in Edge. You could also use Incognito Mode in the same browser or try clearing all your browsing data and cookies, just like when trying to bypass paywalls on popular news sites.
