Excel 1.jpg Excel 2.png

Hi,

My boss gave me this excel file today. It is saved as a .xls file in read only. There are hide/unhide buttons behind the column letter/row number bars. They cannot be right clicked. I have to duplicate it. I can make macros which will hide/unhide selected columns and rows, but how do I position them as in the attached pictures? Also, would it not also be saved as a .xlsm file?

Thanks in advance for any help!
