Click on File

Click on Close

There is not normally an icon available on the toolbar for this function. The other way in which you can close a file is to use the buttons on the very top right of the screen. Notice that one set of buttons appears in the blue status bar. This is not the set of button that I am referring to (these buttons refer to the whole programme and that X will close the Word programme).

I am referring to the second row of buttons in the grey area. I have attempted to place a circle around the X that I am referring to. The second row of buttons refer to the document with which you are working. If you want to close the document, carefully click on that X in the second row.

Note: You should normally save your work to disk before closing a programme. If you do not do this, you will lose your work. If you have accidentally forgotten to save your work, Excel will notice this and you will be asked whether you want to save it. the following pop-up screen appears.

Click on Yes if you want to save the work. A save pop-up screen appears.
If you do not want to save the work, click on No.
If you do not want to close (exit) Excel, click on Cancel.
