Hello Danielle0122 

Your message lacks a lot of details. Maybe explain what you are trying to do will help.

But I do know that MS-Excel workbosks can get corrupted and that is terrible to have happen.

If you can look at this and find what may work for you it will be a starting point

Otherwise add some images of these dots that you see and explain more.
