How do I add money to cash?

Excuse me, I'm a bit confused about the concept of "adding money to cash." Could you please elaborate on what you mean by that? Typically, cash itself represents a form of money that is readily available for use, such as paper bills or coins. Are you perhaps asking about how to deposit cash into a bank account, or how to exchange cash for another form of currency, like cryptocurrency? If so, the process would depend on the specific method or platform you're using. Could you please clarify your question so I can provide a more accurate answer?
