How to close Excel-file after writetable()?

I want to use writetable() for an Excel-file in a for-loop. But at the second loop it stops with an error, because the first file is still open and there is no permission. Before I'd open a new folder for the new excel-file, but it doesn't work in this way now, because the file is still open.

I got this from the Mathworks directly:

You can use the following SYSTEM command via MATLAB to kill the process:

>>   system('taskkill /F /IM EXCEL.EXE');

Many thx. It works perfect! :-)

You're welcome. Can you go ahead and "Accept this answer" then? Thanks in advance.

Hi Image Analyst,

instead of closing excel completely with unwished consequences I've found a similiar command like following which only is closing the specific spreadsheet:

system('taskkill /F /FI "WINDOWTITLE eq xy*"');

But once more thanks for your hint, because this was the way to solve it!

I created an excel file named Comparison.xlsx. How do I only close that excel uding this command?

have a look at the answert above from @Reinhard Palaver, this is basically what you want

Answer 2

Now I've an addtional problem. In a for-loop I've to use wait, until the batch is finished, otherwise it doesn't work in they way I want to have. And it's closing "all" excelfiles.

So now I'm looking for a function to close only the specific file after writing.

Use table2cell() to create a cell array, and use xlswrite1() from the File Exchange, as that gives you an interface in which you have specific control over closing the spreadsheet.

[Reinhard Palaver]

Okay and thanks. I've already used xlswrite, but I'ven't seen any options or parameter to control closing excel-sheet!

[Walter Roberson]

You can deduce it from the Description -- you would invoke the workbook save function when you were finished writing, and then invoke the workbook close function to close that connection. Eventually you tell the excel session to quit, after you have written out all the files.

[Image Analyst]

% Open Excel
Excel = actxserver('Excel.Application');
excelWorkbook = Excel.workbooks.Open(excelFullFileName);
Excel.visible = true; % Make Excel appear so we can see it, otherwise it is hidden.
% Call xlswrite1().....
% Save the workbook
Excel.ActiveWorkbook.Save();
% Close the workbook.
excelWorkbook.Close(false);
% Shut down Excel.
Excel.Quit;

See attached demo.

I am getting the following error:

Undefined function or variable 'workbooks'

[Image Analyst]

You must have changed the file. There is no workbooks variable in the attached function. You forgot to give the complete error which included the line of code so I don't know how you modified the function. Nevertheless, that demo is from 4 years ago and I have a new one, which I'm attaching here. And I just ran this so I know it works.

Plus I attached a second, separate demo showing how to put a formula into an Excel cell.
