Reading multiple excel files from a folder that has other types of files in addition to excel and putting the values in a cell array

I have a folder in which there are files of many types(.csv,.xlsx,.jpg,.mat,etc.) and my objective is to filter out only the excel files, read the values of third column(C) of each excel file and put them into the matrix or cell array.

I don't have any idea on how to write a program that will only read excel files. Below is the following code I wrote using actxserver.

function startServ1

       exl = actxserver('excel.application');
       exlWkbk = exl.Workbooks; 

        folder='C:\Users\shankyaw\Desktop\plot';
        FilteredFiles = dir([folder '/*.xlsx']);
        sd = length(FilteredFiles);
        N_File = numel(sd);
        %exlData = cell(1,N_File);

for e = 1:N_File

      exlFile = exlWkbk.Open([folder '/' FilteredFiles(e).name]);  
      exlSheet1=exlFile.Sheets.Item('sheet1');
      robj = exlSheet1.Columns.End(4);
      numrows = robj.row;
      dat_range = ['C1:C' num2str(numrows)];
      rngObj(:,e) = exlSheet1.Range(dat_range);
    end

    exlData = rngObj.Value;

    exl.registerevent({'WorkbookBeforeClose',@close_event1});
    end % startServ1

Can someone help me how to get this reading done. Thanks.

sdirectory = 'D:\EXAMPLE_directory';
tifffiles = dir([sdirectory '/*.xlsx']);
sd = length(tifffiles);
for k = 1:numel(sd)
     File1 = [sdirectory '/' tifffiles(k).name];
     A = xlsread(File1)
end

Thanks a lot. do you know how to do this using actxserver instead of xlsread? xlsread is not very ideal for my project because xlsread is very slow.
