be more precise: which part is NOT working(?); WHAT do you expect from
the output/loop(?)...

Apologies for being unclear. I've re-ran the code and it worked fine. Here's the problem: i have three csv files and i want to import them onto Matlab as three seperate VARIABLES. With the current code, the output would be 'data1', but that would contain the data from the last csv file.

So, is there any way to store my csv files in seperate variables without overwriting any of them? Any help appreciated. Thanks.

Perhaps you should consider storing the data in a cell array:

csvFiles = dir('*.csv');

filename = cell(length(csvFiles),1); % preallocate
data = cell(length(csvFiles),1); % preallocate

for k = 1:length(csvFiles)
filename{k} = csvFiles(k).name;
data{k} = importdata(filename);
end

well...
either

filename=csvFiles(k).name;

or

data{k}=importdata(filename{k});
