The expression "no sooner said than done" is used when someone quickly does what they have just said they would do. For example, if someone says "I'll go get the book right now", and then they immediately go get the book, you could say "no sooner said than done". It means that the person did exactly what they said they would do without any delay. It is often used to show admiration or approval for someone's quick action.
