Quickly detect any differences between two documents in Word
Quickly detect any differences between two documents. On the Review tab, in the Compare group, click the Compare button. Your choices are Compare or Combine. Either one will give you a look at the differences. However, Combine will allow you to generate a third document that gives you the opportunity to include differences by accepting them.
When you initially compare the documents, the screen may look a little busy. Feel free to close down panels that aren’t useful. You have the option to choose Show Source Documents or not with an active Combine on the screen.
