Take number from excel in App Designer

Hi, I want to load numbers from my excel, I first used readcell but it gives me this error:

I have this numbers, and I used xlsread, it works but only worked for the first 9 (all cells from C3 to C11), but when I try to read the others (C13 to C24) gives me the same error.

Theres a way to read numbers using readcell (or another option), and if I need to use xlsread, why the firsts works perfect but the next numbers no?

readcell returns a "cell" value but not a double scalar. This is where you made a mistake.

Let me convert cell to double.

First, let's generate cell sample:

c = {1}

c = 1×1 cell array
    {[1]}

and this can be converted to double as follows:

cmat = cell2mat(c)

cmat = 1

class(cmat)

ans = 'double'

The cmat is a double scalar and this is the data format that your components asks for.
