ANSI ASC X12 is a way that grown-ups use to talk to each other about important information. You know how sometimes you draw pictures to explain something? Well, these grown-ups created special words and numbers that help them explain important things that they need to share with others.
Imagine you are playing a game with your friends, but everyone has a different set of rules. It would be very confusing! But, imagine everyone follows the same set of rules. That makes the game much easier to play and everyone can understand what is happening.
ANSI ASC X12 is like a big book of rules that everyone agrees to use when they need to send important information to each other. It helps everyone communicate in the same way, so they can understand each other and make sure important things get done as they should.
For example, if you were to ask your mom to buy some cookies for your birthday party, you would need to tell her how many you want, what kind you like, and where she can buy them. Using ANSI ASC X12, grown-ups can use special words and numbers to tell each other things like this quickly and easily.
It's like a secret code that only grown-ups understand and use to make sure everyone is on the same page!
