How to for loop readtable and writetable range?

Let's say I have a worksheet consist of words and numbers. I want to change certain cells or cell groups with a for loop. How may I handle it?

data=readtable('test4.xls','ReadVariableNames',0,'Range','Ex:Fx');
writetable(A, 'test4.xls','WriteVariableNames',0, 'Range', 'BX:CX');

I want the "x" values here to be change as for loop goes on from i=1:10, lets say.

(To be more clear, if i = 3 the range will be E3:F3)

Btw, the solution has to in this form ( readtable and writetable) . Since I'm using Ubuntu and couldn't find any other solution for now, to my problem. Other solutions are currently either not avaible in R2018a or does not overwrites to existing .xls file.

%f true
    %if true
for i = 1:10 
R1 = sprintf('%s%d:%s%d',char(069),i,char(070),i);
R2 = sprintf('%s%d:%s%d',char(066),i,char(067),i);
data=readtable('test4.xls','ReadVariableNames',0,'Range',R1);
writetable(A, 'test4.xls','WriteVariableNames',0, 'Range', R2);
end

I got the idea I' ve to change some few, but at the end issue is solved. However, I want to ask is there any other way to write column names other than char(xxx)? If not how may I translate A, B, C .. etc?
