plotting x,y,z vertices as mesh

Hello there,
I have a .xls file that contains x,y,z vertics. The sequence goes something like this: x0,y0,z0,x1,y2,z2,..........x1000,y1000,z1000 (1000data points for each x,y,z)
I am wondering is it possbile to plot all the data using mesh? I plotted only x0,y0,z0 using one of the solutions I reading using trimesh, but there is line between instead of dots. https://www.mathworks.com/matlabcentral/answers/220-3d-plot-from-imported-excel-data
That's what I have so far:
clc;clear;close all;
test = xlsread('data.xls');
x=test(:,2);
y=test(:,3);
z=test(:,4);
x = rand(100,1); % Sample x data
y = rand(100,1); % Sample y data
z = exp(-(x-0.5).^2-(y-0.5).^2); % Sample z data (a 2-D Gaussian)
tri = delaunay(x,y); % Create a 2-D triangular mesh
trimesh(tri,x,y,z); % Plot the mesh in 3-D
Any suggestions and helps please?
Thanks in advance

That approach should work, provided that you remove those 'Sample' lines.
Can you attach your data.xls for testing?

triplot(tri,x,y);

trisurf(tri,x,y,z); % Plot the surface in 3-D
