There is no need to convert it to Excel. It is only necessary to tell readmatrix (introduced in R2019a) that it is a text file, since that is not obvious from the file extension. Otherwise, readtable (inttroduced in R2013b) will work, with a minor modification to the readmatrix code.
Try this —
Uz = unzip('name2.zip')
A1 = readmatrix(Uz{1}, 'FileType','text')
x = A1(:,1);
y = A1(:,2);
figure
plot(x, y)
grid
T1 = readtable(Uz{1}, 'FileType','text')
x = T1{:,1};
y = T1{:,2};
figure
plot(x, y)
grid
.

@mohd akmal masud — As always, my pleasure!
To add axis labels to a 2D plot, use xlabel and ylabel, and to add a title, use title. (There are similar functions for 3D plots and groups of plots such as those produced by the tiledlayout function.)
