Hello everyone, I need to ask how matlab R2017b can read data from an open excel file than write the data to the same file ? Because now it can't run without close the file.
Thank you !

Also, make sure all MS Excel instances are closed before executing the code.

A simple workaround method that might work for some is to make a local temporary copy of the open file and work on that, then copy it back to the original when ready. It is also a safe method of working as it would not touch the original data until told to do so.
The 'system' command can run an OS command, e.g. on a MS Windows machine:
originalfilename='Book1.xlsx';
tempfilename='tmp.xlsx';
system(sprintf('xcopy %s %s /Y',originalfilename, tempfilename));
On MS Windows the 'xcopy' command with a /Y option copies the file and overwrites without prompting. Also xcopy is not blocked by the file being open elsewhere whereas a straight 'copy' is blocked. I'm sure there is a similar Linux command.
