I have an excel file with many columns containing information at the end of each column like this.

It lists car verbage, then 2 blank cells are required , followed by an E.

I was wondering if a macro could be used to where it looks at a column, finds where the verbage ends, and automatically inserts 2 blank cells below it followed by an E. In other words it needs to make sure only 2 blank cells are after the verbage and an e should follow in the cell below. If the column has 3 blank cells below the verbage it should fix it and add the E at the appropriate space.
