Copy rule

Good morning to the whole community.

I am grateful to be part of this consultation forum, since I am beginning to use this great working tool and many times I encounter various drawbacks, of which you are the ones who give me the solution.

Today I come up against the following problem, which I will detail below.

I work with an excel as my database (first image) which has column A combined 3 cells.

At the time of loading that spreadsheet it is seen me generates a problem, since there is space in empty and I do not refer to the days.

I'm currently repeating the value of the day in the 2 cells still, but it's a very tedious job.

What suggestion can you make to me to fix this?

Thank you very much indeed.

Slds.

Joaquin
