Converting a Google Play card to cash is an option that some people may consider. However, it's important to note that such conversions might not always be straightforward or legal through proper channels.

Google Play cards are designed for use within the Google Play ecosystem to purchase apps, games, movies, music, and other digital content. Any attempt to convert them to cash outside of legitimate and approved methods could violate the terms and conditions set by Google.
Moreover, engaging in unauthorized conversions can lead to various risks. There could be potential fraud involved, with scammers offering deals that seem too good to be true but end up leaving you with no cash and a deactivated or unusable Google Play card. It's advisable to use Google Play cards for their intended purpose and explore other legitimate ways to manage your finances rather than seeking unregulated conversions.
