Greetings. I am having difficulties running an automated script that makes an Excel worksheet import data from an external source (a .dat file) using an activex connection from Matlab. Assuming Excel is my activex object, the following should (I think) make Excel import the designated file in cell A1:

% UI: Name the .xlsx file to write to
      [xlfile, xlpath] = uiputfile('*.xlsx', 'Save Workspace as'); Inputsheet=1;
      if isequal(xlfile,0) || isequal(xlpath,0)
         disp('User pressed cancel')
      else
         disp(['User selected ', fullfile(xlpath, xlfile)])
      end   
filename = [xlpath xlfile]; % file directory
% Write a number to the file to make it physical 
xlswrite(filename,1) 
% Retrieve sheet names 
[~, sheetNames] = xlsfinfo(filename);
% Open Excel as a COM Automation server
Excel = actxserver('Excel.Application');
% Open Excel Workbook
Workbook = Excel.Workbooks.Open(filename);
% Clear the content of the desired output sheet
cellfun(@(x) Excel.ActiveWorkBook.Sheets.Item(x).Cells.Clear, sheetNames(Inputsheet));
% Get a handle to the active sheet
Activesheet = Excel.Activesheet;
Excel.Activesheet.Connection.Add(Excel.Activesheet.get('Range', 'A1'), 'TEXT','C:\Users\isc.ISC1\Desktop\Matlab Programs\GTstrudl Output Postprocessing\WD-ULS-PUNCHING-JACKET-WEAK-LRFD.DAT')

% END

but the code gives me the error message:

Excel.ActiveSheet.Connection.Add(Excel.Activesheet.get('Range', 'A1'), 'TEXT','C:\Users\isc.ISC1\Desktop\Matlab Programs\GTstrudl Output Postprocessing\WD-ULS-PUNCHING-JACKET-WEAK-LRFD.DAT')
No appropriate method, property, or field Activesheet for class handle.handle.
