How do I make a code that store large amount of information from excel into a matrix?

I'm trying to recreate the following data in excel sheet and store them in a matrix using MATLAB. Unfortunately, I could not think of the best way to handle this amount of information using MATLAB. Below I have attached the current code that I have and the excel sheet.

clear
clc

numData1=xlsread('Original2.xlsx','original');
FrontFaceElements1=numData1(:,1);
FrontFaceElements1_stress=numData1(:,2);

%Total elements and nodes

%Assemble all nodes and its coordinates in a single matrix
TotalNodes=numData1(:,13);
TotalNodesX=numData1(:,14);
TotalNodesY=numData1(:,15);
TotalNodesZ=numData1(:,16);
TotalNodesMatrix(:,1)=TotalNodes;
TotalNodesMatrix(:,2)=TotalNodesX;
TotalNodesMatrix(:,3)=TotalNodesY;
TotalNodesMatrix(:,4)=TotalNodesZ;

TotalElements=numData1(:,18);
TotalElementstress=numData1(:,19);

%Coordinates of each elements

admittedly, I feel a bit stuck about this. Rather than continuing, I’m wondering if I could lean on your expertise and insights to learn how to do it. Appreciate any form of help. Thank you soo much :)

so what are you trying to do?

Good question haha. I'm trying to create a loop matrix that starts from 1X1 (value 15 as shown in the picture) to the final row lets say nX1. At the same time, it saves all the nodes corresponds to the element as shown in the figure.

I really appreciate it if you could give an opinion about this.

Are you trying to do this:

m = numData1(:,[1:12]);

this should give you a matrix with the first row corresponding to the element number, and the other columns being the node data

yes! thank you soo much. I really appreciate it. I'm surprised, why didn't I thought of that.
