Dear matlab expert, I have 2 excel data . The first one is the main data, the other one is the output file. I want to copy each column of the main data to the third column of the output file one by one with the header still on and save it as txt format for each copy. How can copy each column and make a multiple output file all at once?

mainfile=readtable('MainData.xlsx');
outputfile=readtable('Output.xlsx');
C=cell(size(mainfile,2),1);
for i=1:size(mainfile,2)
outputfile(:,3)=mainfile(:,i);
result=[outputfile(:,[1 2]) outputfile(:,3) outputfile(:,4)];
C{i,1}=table2cell(result);
end
mat=[C{:}];
% making text files
for j=1:4:size(mat,2)
col= mat(:,j:j+3);
writecell(col,[num2str(j) '.txt'])
end

try this:
mainfile=readtable('MainData.xlsx');
outputfile=readtable('Output.xlsx');
C=cell(size(mainfile,2),1);
for i=1:size(mainfile,2)
outputfile(:,3)=mainfile(:,i);
result=[outputfile(:,[1 2]) outputfile(:,3) outputfile(:,4)];
C{i,1}=table2cell(result);
end
mat=[C{:}];
varname={'Lat','Lon','PWV','STA'};
repitvar=repmat(varname,1,size(mat,2)/4);
mat2=[repitvar;mat];
% making text files
for j=1:4:size(mat2,2)
col= mat2(:,j:j+3);
writecell(col,[num2str(j) '.txt'])
end
