A formal/informal way to say I don't want anything


I was told that is ok to use

> 何でもないが欲しいです。

in an informal setting for "I don't want anything."

Is this correct? And what is an expression I can use in a formal situation?




If the scenario were saying "I don't want anything" in response to someone
offering you something (food, drink, etc.), you could also use

> （私は）[結構]{けっ・こう}です。 → I'm fine/all right.
