I have a file excel with x,y coordinates and stresses for z coordinate in order to plot a 3D surface.
How can I get this surface with latex interpreter and colorbar?
I attach the excel file.

Try something like this —
T1 = readtable('', 'VariableNamingRule','preserve');
% First10Rows = T1(1:10,:)
T1Sz = size(T1)
T1Sz = 1×2
69696 3
VarNames = T1.Properties.VariableNames;
N = 50; % Interpolation Matrix Size
xv = linspace(min(T1{:,1}), max(T1{:,1}), N); % Create Vector
yv = linspace(min(T1{:,2}), max(T1{:,2}), N); % Create Vector
[Xm,Ym] = ndgrid(xv,yv); % Create Interpolation Matrices
Zm = griddata(T1{:,1}, T1{:,2}, T1{:,3}, Xm, Ym); % Interpolate
Warning: Duplicate data points have been detected and removed - corresponding values have been averaged.
surfc(Xm, Ym, Zm)
grid on
hcb = colorbar;
xlabel(VarNames{1}, 'Interpreter','latex')
ylabel(VarNames{2}, 'Interpreter','latex')
zlabel(VarNames{3}, 'Interpreter','latex')
Experiment to get different results.
