The idiom "all it's cracked up to be" means that something is as good as people say it is or as it is advertised to be. It is often used to express disappointment when something doesn't meet one's expectations.
For example, if someone says, "I heard that new restaurant is amazing," and you go there and find the food to be just okay, you might say, "It wasn't all it was cracked up to be."
Similarly, if someone says, "I got a new job with a big salary," but then realizes the job is very stressful and demanding, they might say, "It's not all it's cracked up to be."
In short, this idiom is used to describe something that doesn't live up to its hype or expectations.
