title: Sharing xlsm file
body: <p>I have an xlsm file located in my work place internal server. Say we are 2 workers who use this file, which includes 2 sheets, <code>My_sheet</code> and <code>His_sheet</code>.</p>
  
  <p>I’m trying to find way for each one of us to work on “his” sheet, means I can edit and save only <code>My_sheet</code> when my co-worker edits <code>His_sheet</code>.</p>
  
  <p>I managed to add a little input box at the opening of the file (Workbook) which, by the different passwords we put there, results by protecting the right sheet and unprotecting the other and this works OK.</p>
  
  <p>My problem is actually the “sharing”:</p>
  
  <p>Is there a way for us to work on this file at the same time (simultaneously) and save our changes?</p>
  
  <p>I tried the Excel Share option but it blocks everything. The other option I found  is using Google’s cloud but it is impossible for us to use it; we have to leave the file “inside the company”… besides, I understand  it doesn’t support scripts so this isn’t an option.</p>
  
  <p>Appreciate every help!</p>
