how to close an excel file

149 次查看(过去 30 天)
Hellow everyone . i am using
winopen('myfile.xlsx')
to open an excel file , after doing some modification, i want to close the excel file in order to overwrite the existing data by
xlswrite('myfile.xlsx', my_modified_data )
but sometimes i forgot to close the file manually in between and MATLAB generates an error . Is there any way to automatically close the excel file(by some command like winclose or something like that) before writing into it . Thank You all .

Yes. You can use actxGetRunningServer() to connect to Excel and shut it down.

works for powerpoint as well - theres not much info online for how to with powerpoint
import mlreportgen.ppt.*
taskToLookFor = 'Powerpnt.exe';
% Now make up the command line with the proper argument
% that will find only the process we are looking for.
commandLine = sprintf('tasklist /FI "IMAGENAME eq %s"', taskToLookFor)
% Now execute that command line and accept the result into "result".
[status result] = system(commandLine)
% Look for our program's name in the result variable.
itIsRunning = strfind(lower(result), lower(taskToLookFor))
%closes powerpoints if they are open so system does not crasah when it
%tries to open a new PP
if itIsRunning
if exist('Plotted Circulator', 'file')==0
system('taskkill /F /IM POWERPNT.EXE');
end
else
end

@Ihaveaquest if Excel is open with several sheets, you can use
Excel = actxGetRunningServer('Excel.Application');
to get a handle to the Excel server, then use Excel to save the active sheet and close it.
Excel.ActiveWorkbook.Save;
Excel.ActiveWorkbook.Close(false); % The 'false' argument prevents the popup window from showing, forcing the closure without user intervention.

Try this:
close all

And when/if you do, you'll see that close does not shutdown other processes and applications like Excel.
