Picture a bag or bowl full of beans being knocked over. The beans fall out and scatter everywhere, so the contents are no longer hidden or controlled. That is the literal image behind spill the beans.

In everyday English, spill the beans means to reveal a secret or share information that was supposed to stay private. The secret comes out too early, often by accident. You can use it for small personal secrets, surprise plans, or information someone else wanted to keep quiet.

"Who spilled the beans about the party?" means someone revealed the surprise.
