You can get my readfile function from the FEX. If you are using R2017a or later, you can also get it through the AddOn-manager.
The readlines function was introduced in R2020b and will work similar to readfile (except it will read to a string instead of a cell array of char arrays).
data=readfile('https://www.mathworks.com/matlabcentral/answers/uploaded_files/486763/aba.txt');
if isempty(data{end}),data(end)=[];end %strip trailing empty line if the file ended with a newline
for n=1:numel(data)
if ~strcmp(data{n}(1),'*')
str=data{n};
%trim leading/trailing whitespace
str=strtrim(str);
%trim internal double spaces
removed_double_spaces=inf;
while removed_double_spaces~=0
length1=length(str);
str=strrep(str,' ',' ');
length2=length(str);
removed_double_spaces=length1-length2;
end
%store back to cell array
data{n}=str;
end
end
fprintf('%s\n',data{:})

ok
so my 2 cent suggestion to make that array looks nicer -
lines = readlines('aba.txt','WhitespaceRule','trim');
ll_out = strings; % init string array
for ci = 1:numel(lines)
ll = lines(ci,:); % current line
if ~startsWith(ll,'*'); % check lines 10 to 20 - here we have to work things out
lldk = strrep(ll,' ',''); % remove all (multiple) blanks inside the char array
ll_out(ci,1) = strrep(lldk,',',', '); % put back one blank after the comma (if really needed)
else % nothing to do except copy the original line
ll_out(ci,1) = ll;
end
end
% save it - and remove the double quote
writematrix(ll_out, 'test.txt',"QuoteStrings",0)
