I have a data store in .csv files. in the data i have vector of number that i want get in cell not in string (and some more data that i want in separate cell). because the vectors are not in same length i don't want it to be numbers.
Can we use xlsread or other function and store cell variable (in cell matrix)? If not what is the easiest way (format?) to store the data in csv file to change it in matlab from string/array to cell variable?
example file is attached

Lets try the following, I hope this can help:
function C = claimReader()
inp = csv2struct(['C:\Documents and Settings\nkulczy\My Documents\085 Starry Sky\','Starry_Sky_inputs_vert.csv']);
inputTitles = [{'Output_Dir'};{'Claimz'};{'Prodz'};{'Fault_Locations'};{'Fault_Type'};{'Primary_Failed_Part'};{'Part_Group'};{'Selected_SEAG'};{'Change_Point'};{'Date_Compile'};{'Minimum_Date'}];
claim = inp.(cell2mat(inputTitles(2))); %returns a file path/location string
C = csv2struct(claim);
end
function Out = csv2struct(filename)
%%read xls file with a single header row
[~, ~, raw] = xlsread(filename);
[~ , ~, ext] = fileparts(filename);
if ~strcmpi(ext, '.csv') %convert non .csv files to .csv, so blanks stay blank
filename=[pwd,'tempcsv',datestr(now,'yymmddHHMMSSFFF'),'.csv'];
xlswrite(filename,raw);
[~ , ~, raw] = xlsread(filename);
delete(filename);
end
if size(raw,1)==11 && size(raw,2)==2 %transpose SS inputs (must match dimensions of input matrix EXACTLY!!!)
raw = raw';
end
nRow = size(raw,1);
nCol = size(raw,2);
header = raw(1,:);
raw(1,:) = [];
end

I don't quite understand the question, but I'll take a guess. You can use csvread() to read in your data file, and xlswrite() to write it out to an Excel workbook. Does that answer the question?

no. i know how to read. my question is if i have an array saved in the file in format [1,2,3,4,5]. by xlsread() it export to matlab like a string. my question is if it is a way to get it in cell variable that contain an array.

I still don't understand. How are you saving by xlsread()? xlsread() opens an Excel workbook and imports it into MATLAB. xlsread does NOT save an MATLAB variable/array in a file.
You say you "know how to read." Well, that reading is done by xlsread() so you say you know how to do it. Well if you do , then why are you asking how to read the workbook into a cell array???? That's exactly what xlsread, which you say you know how to use, does so why are you asking? Please clarify, or get a native English speaker to help translate.

[xd,~,xcell]=xlsread('example2.csv');
In XCell(:,2) i want that column B ([139,53,33,20,12,11,8,6,5,5,3]) will be Cell of number and not a string.

Try this:
[xd, ~, xcell]=xlsread('example2.csv');
[rows, columns] = size(xcell)
for row = 1 : rows
% Extract string.
str = char(xcell(row, 3));
% Get rid of brackets
str = str(2:end-1);
% Turn into numbers and put in cell
column3{row} = sscanf(str, '%d, ');
end
% Display the cells
celldisp(column3)
column3

In a very different approach,
Use
textscan
instead of
slxread or csvread
