extra rows and columns outside of my spreadsheet

Hi charlie1951 

Try this solution from a previous post to Hide the columns instead.

In saying this the extra rows and columns do no harm to your workbook but if you want them visually gone, the above method will work a treat.

Hope that does the trick for you.

Cheers
