This macro shows a basic concept of how to find the last row/column. In this form, it is not very useful, at least for me, but customizing it, it is totally useful. In the other hand, in this other topic Know the last column letter of a row using a macro in an excel report, I explain how to find the letter of the last column of a row.
When I use the macro ?
For instance, I need to find the last column then the last cell of this same column because all cells in this range are formulas so it will copy and paste this range to the next column.
