I am new to writing VBA code in Excel:

I have a simple spreadsheet with 2 columns. The first column has an animal
ID, the second has the animal data. The first column has 1 cell filled in
for a set of 2-6 cells in the second column, therefore below the filled in
cell are blank cells until the next animal ID.

I would like to create a simple macro that will search the first column (A),
when it finds a cell that is blank I would like it to copy the cell above it
and paste it into that cell. If the cell is not blank then leave it as is.
This is all on the first sheet of my workbook (Sheet1).

If someone could help me write the code for this that would be great, I'm
assuming it should be that hard. Thanks!
