title: Writing data to Excel spread sheet while open
body: <p>Currently, I am writing a python script that handles excel data using OpenPYXL. I am trying to create an interface in excel that updates data in the spreadsheet cells in a cyclic way. I understand that I cannot write to an open excel file, as it gives me a permission error. Is there a way to bypass this without having to close the file and run the script every time new data is to appear?</p>
