How to avoid Excel output being processed by alteryx

[philosophy22]

hello, there

I am using alteryx do some data analysis and using excel template as my output, when I finish my workflow it will override the template. However, I am confused when i open the output, it warns me excel is being processed by another user, but the alteryx workflow is finished in this situation. The excel only have read access. How can i avoid this situation when finish the workflow? Thanks in advance!

To conclude, check if there is another process is using the file, like some automation.
