It will fill up automatically the missing months or the missing number. For instance, I have in the cell A1 January, it will put the other months from cell A2 until the end of the year or until 10 years. It will do the same thing if I have 1, so from next cell, it will put 2, 3, etc.
When I use the macro ?
For instance, when I am preparing the report for the next year, I need to fill up the months automatically.
