title: Using github for excel files
body: <p>As a kind of follow up of <a href="https://stackoverflow.com/questions/48902377/using-git-for-non-programming-work">this question</a>, I would like to ask regarding binary files (such us excel files) and versioning. </p>
  
  <p>Let's say I want to use github to store a programming project. No problem there since the majority of files are text (no matter the language).</p>
  
  <p>But I have also documentation. What if I put it into a folder of the github project? (I have seen projects that do this)</p>
  
  <p>I read git is no good for this, so how can I work versioning for say excel files?</p>
