You can't delete them but you can lock them, by selecting the whole sheet,
then go to protect sheet, and make sure to uncheck the box with select locked
cells, and press OK.

I am working on an excel spread sheet. I only need to have 9 columns for
what I want to do. The columns are from A to J. Is there a way of deleting
the rest of the columns or making them inactive. This makes it easier
especially when blocking a row. It would not be row of 702 columns but only
of 9 columns?
