Comparing Document Versions

Written by Allen Wyatt (last updated April 9, 2022)
This tip applies to Word 2007, 2010, 2013, 2016, 2019, Word in Microsoft 365, and 2021

Word includes a tool that allows you to compare two documents to each other. The document in memory is marked with revision marks to indicate the changes from the document on disk. You perform a comparison in this manner:

Display the Review tab of the ribbon.
Click the Compare tool and then choose Compare. Word displays the Compare Documents dialog box.
Click the More button, if it is available. (See Figure 1.)

Figure 1. The Compare Documents dialog box.

At the top-left of the dialog box, click the file-folder icon to select your first file.
At the top-right of the dialog box, click the file-folder icon to select your second file.
Change the comparison settings, if desired.
Click OK.

When the comparison is done, Word shows the original documents and the compared document, which contains revision marks (using familiar Track Changes markup) to indicate what has changed.
