I am using following code:
command='netstat -e'
[status,cmdout]=system(command)
Result:
cmdout =
'Interface Statistics
Received Sent
Bytes 4178033452 510183200
Unicast packets 124836 2463020
Non-unicast packets 30732 38568
Discards 0 0
Errors 0 0
Unknown protocols 0
'
The cmdout is char file (1x371).
I wish to get this data in table form (row x column) or in excel format or as matrix. Please guide. Thank you in advance

What have you tried so far yourself? Splitting the char on newlines is the easiest part, but splitting the char to columns should not be too hard either.

I have tried following things:
str=convertCharsToStrings(cmdout)
t=table(str)
cel=table2cell(t)
array=table2array(t)
st=table2struct(t)
s=reshape(array,[1,15])
but none has helped. Thanks for response

Ran in:
cmdout = fileread('cmdout.txt') % fake data
cmdout =
'Interface Statistics Received Sent Bytes 4178033452 510183200 Unicast packets 124836 2463020 Non-unicast packets 30732 38568 Discards 0 0 Errors 0 0 Unknown protocols 0 '
hdr = regexp(cmdout,'^\s*(\S+\s\S+)\s+(\S+)\s+(\S+)\s+(.*)','tokens','once');
tkn = regexp(hdr{end},'(\S+(\s\S+)*)\s+(\d+(\s+\d+)*)','tokens');
Method one: UINT64:
tmp = vertcat(tkn{:});
mat = sscanf(sprintf(' %s',tmp{:,2}),'%lu',[2,Inf]).';
tbl = array2table(mat, 'RowNames',tmp(:,1), 'VariableNames',hdr(2:end-1))
tbl = 6×2 table

Method two: DOUBLE:
tmp = regexprep(vertcat(tkn{:}),'^\d+$','$& NaN');
tbl = array2table(str2double(split(tmp(:,2))), 'RowNames',tmp(:,1), 'VariableNames',hdr(2:end-1))
tbl = 6×2 table

It's a little circuitous, but you can use writelines to write the char vector to a text file, then use the power of readtable to parse it into a table in MATLAB.

This was introduced in R2022a, so you might be using an earlier version, (or missing the "s" at the end).

You have fixed-width columns. Use array indexing:
topic = string(cmdout(5:end, 1:22));
received = double(string(cmdout(5:end, 23:35)));
sent = double(string(cmdout(5:end, 36:end)));
T = table(topic, received, sent);

Sir actually I have marked a response as accepted which was suggested earlier. This too was also working and I am unable to accept this answer.

No, you flagged a comment. A flag is meant to attract the attention of an admin, not to indicate the solution to a question.
You can indeed not accept a second answer. What you can do is unaccept the previous one, and accept this answer.
