The idea of converting a $75 Google Play card to cash might seem appealing to some. However, it's important to note that Google Play cards are designed for use within the Google Play ecosystem, such as purchasing apps, games, movies, and other digital content.

Legitimate methods for directly converting a Google Play card to cash do not exist. Google has strict policies against such practices. Any attempt to find a way to turn these cards into cold hard cash through unauthorized means is likely to violate the terms of service and could lead to serious consequences.
Moreover, engaging in illegal or unethical conversions not only goes against the rules but also exposes individuals to potential fraud and security risks. It's best to use Google Play cards for their intended purpose and enjoy the digital offerings available on the platform. Instead of looking for ways to convert them to cash, focus on exploring the wide range of entertainment and useful applications that can be obtained with these cards.
