Error with importdata when looping through files in folder

Hi all,
I'm currently trying to build a script that will run through a folder full of awkward .txt files that need converting via excel to .csv, whilst stripping out some unwanted cells that contain unwanted data to give me a 512 x 16 table of values and saving these in a new folder as .csv, although I keep getting an importdata error as it's unable to open the files.
I've had a look through my code but can't find the issue exact, but I have a feeling it might be something to do with strcat and fullfile as I've had that issue before.
Any help would be appreciated. Thanks!
data_path = 'C:\Users\nicol\Desktop\RAII-H16-F11-HM2\Fat\';
% specify where to save smoothed files
new_path = strcat(data_path, 'csvcropped/');
if ~exist(new_path, 'dir')
mkdir(new_path);
end
search_string = fullfile(data_path, '*.txt');
% find all files matching search string
files = dir(search_string);
for i = 1:numel(files)
filename = files(i).name;
name = regexprep(filename, '.txt', '');
raw_data = importdata(filename);
text_data = raw_data.textdata;
cropped_data = text_data(25:536);
tmp = cellfun(@(x)regexprep(x, '(Pixel\s+\d{1,3}:\s+)', ''), cropped_data, 'UniformOutput', false);
data_cell = cellfun(@(x)regexp(x, '\d+', 'match'), tmp, 'UniformOutput', false); clear tmp;
processed_data = array2table(str2double(table2array(cell2table(data_cell))));
new_filename = [name '.csv'];
writetable(data, strcat(new_path, new_filename), 'WriteVariableNames', false);
end

Can you please mention what is the exact error you are getting and at what line?

raw_data = importdata( fullfile(data_path, filename));
I know that you do
search_string = fullfile(data_path, '*.txt');
but remember that the name field of the output of dir() is only the basic file name without any directory part.
