I have heterogenous data (see textfile) and I am trying to modify my code such that it gives the same output as readtable('kimetsu.txt') and then finally readcell('kimetsu.txt'). I need help modifying it
Text = 'kimetsu.txt';
request = fopen(Text);
clear t
while ~feof(request)
line = string(fgetl(request));
line = line.split(",")';
line = array2table(line);
if exist("t","var")
t = [t; line];
else
t = line;
end
end
for j = 1:width(t) %this is the crucial part (I think) when it comes to modifying the code
t.(j) = str2double(t{:,j});
end
desired output without using readcell
ans =
5×5 cell array
{'Corps members'} {'Names' } {'Nichirins'} {'Lcs'} {'Sw'}
{[ 1]} {'Shenobu'} {[ 99]} {[ 23]} {[67]}
{[ 2]} {'Rengoku'} {[ 78]} {[ 10]} {[23]}
{[ 3]} {'Tanjiro'} {[ 10]} {[ 21]} {[98]}
{[ 4]} {'Akaza' } {[ 500]} {[ 89]} {[11]}

Ran in:
T = fileread(Text);
C = strsplit(T, newline);
Head = strsplit(C{1}, ',');
Body = reshape(split(C(2:end), ','), numel(C) - 1, []);
Num = str2double(Body);
Body(~isnan(Num)) = num2cell(Num(~isnan(Num)));
Result = [Head; Body]
Result = 5×5 cell array
{'Corps members'} {'Names' } {'Nichirins'} {'Lcs'} {'Sw'} {[ 1]} {'Shenobu'} {[ 99]} {[ 23]} {[67]} {[ 2]} {'Rengoku'} {[ 78]} {[ 10]} {[23]} {[ 3]} {'Tanjiro'} {[ 10]} {[ 21]} {[98]} {[ 4]} {'Akaza' } {[ 500]} {[ 89]} {[11]}

Hi Jan. I am getting an error
Error using split (line 99)
Element 5 of the text contains 0 delimiters while the previous elements have 4. All
elements must contain the same number of delimiters.
Error in Untitled (line 5)
Body = reshape(split(C(2:end), ','), numel(C) - 1, []);

This does not happen for me, if I use the input you have provided. If you use another input, please post it.
Maybe your file contains blank lines ate the end? Then:
T = fileread(Text);
C = strsplit(T, newline);
C(cellfun('isempty', C)) = []; % Inserted line
