This tool closes all open files (workbooks) that have not been changed since they were last saved.

This is a quick way to clean your workspace after opening several files just to view or check them, without making any changes.

Any files that have unsaved changes will stay open, so you won't lose any work.

It's useful when:

• You've opened many workbooks to review but didn't change them
• You want to quickly close all unchanged files without closing everything
• You want to avoid accidentally closing unsaved work

How it works:

• Files without changes since the last save are closed automatically
• Files with unsaved changes stay open, so you can review or save them manually
