Could you provide more details about your problem? (your trials, your code, etc..)

Use readtable() or xlsread() to read the data. Once it is read into MATLAB, MATLAB does not care where it came from, so it becomes just the same as using any other array or vector when you construct the objective function to minimize.

Use whatever is appropriate for your purpose and your solver.
Example:
t = readtable('YourFile.xlsx');
x = t.x;
y = t.y;
model = @(P) P(1)*log(x) + P(2)*x.^2 + sin((P(1)+P(2))*pi*x);
residue = @(P) sum((model(P) - y).^2);
nvars = 2; A = [1 -1]; b = 0; Aeq = []; beq = []; nonlcon = [];
[bestP, fval] = ga(residue, nvars, A, b, Aeq, beq, nonlcon);
