See the FAQ: https://matlab.fandom.com/wiki/FAQ#What_is_a_cell_array?
Let's say element 1 of your cell array has a string that is the filename, like
ca{1} = 'C:\Users\Katherine\Documents\MATLAB\work\someProject\Project Data.csv';
Now you can use that in your MATLAB code like this:
fullFileName = ca{1}; % Extract filename from cell.
% Check if file exists.
if isfile(fullFileName)
% File exists. Read in its data.
data = readmatrix(fullFileName);
else
% File does not exist. Alert the user.
warningMessage = sprintf('Warning: "%s" does not exist!', fullFileName);
fprintf('%s\n', warningMessage);
uiwait(warndlg(warningMessage));
data = [];
end

To convert the value in your cell array to a file name, you can can use the curly braces `{}` indexing operator in MATLAB. I can give you an example, and here it is:
% assuming your cell array is named 'fileNames'
fileName = fileNames{1}; % getting the 1st element of the cell array
% you can use 'fileName' as the file name in your code
% suppose you want to read the contents of the file
fileContents = fileread(fileName);
In the above code, `fileNames{1}` is getting the 1st element of the cell array `fileNames` and assigns it to the variable `fileName`now you can then use `fileName` as the file name in your subsequent code.
Hope it will help you
~Thanks
