Excel. Save and close a file.

Hi, I'm trying to create a macro that when selected, will save and close the file it is placed in. People keep adding info to a shared file but then not saving. I'm going to tell them that to exit the file they MUST click this button.There lots of different threads about similar items but can't find one that simply does this.
Can anyone please help?

Brilliant. Thank you! Will now mark as solved.
