How to Compare Two Word documents?

Comparing documents in Microsoft Word's desktop application is a straightforward process, though it might not be immediately apparent. Here's a simple method to achieve this. (Note: The web version of Word does not have a built-in tool for document comparison.)

Step 1: Begin by creating a new document in Microsoft Word.

Step 2: Navigate to the upper ribbon and select the "Review" tab.

Step 3: Click on "Compare," followed by "Compare Documents" to initiate the document comparison process.

Step 4: Within the Compare Documents window, make adjustments to the following fields:

  • Original document: Select the initial document for your comparison.
  • Revised document: Choose the alternative version of the document intended for the comparison.
  • Label changes with: Simplify the identification of differences by assigning a label, such as the writer's name, to highlight alterations in the revised document.
  • In: By default, Word showcases changes between the two documents in the original document. For a clearer comparison and the ability to revert to the original version if needed, opt to compare documents in a new document. To enable this, click on "New document" in the Show Changes section. (If this option is not visible, click the downward caret [∨].)

Step 5: Hit the OK button

Following this, Word seamlessly combines the two documents and annotates distinctions as comments in the Markup Area located beside the document. If you're reviewing only the document itself, Word takes it a step further by highlighting variances with a distinct red font color and underlining the differing text.

How to Merge Word Documents?

If you aim to integrate all modifications from the second version into the content of the original document while eliminating any markups, follow these simple steps after comparing both documents.

Step 1: Locate the downward caret (∨) adjacent to Accept in the Review tab.

Step 2: Opt for Accept All Changes for a swift merging process. Alternatively, choose Accept and Move to Next to personally review each alteration and selectively merge edits.

How to Compare Documents in Google Docs?

Comparing documents in Google Docs follows a slightly different process than in Word, but it remains equally simple. Here's how you can do it:

Step 1: Begin by opening the initial document you wish to compare.

Step 2: Next, navigate to the menu, click on Tools, and then select Compare documents.

Just like in Word, Google Docs captures variances from the second document as comments. To provide a quick overview of distinctions within the document, Google Docs highlights changes with a distinct font color, allowing users to easily identify and comprehend alterations right in the document.

Google Docs doesn't have a dedicated tool to combine two documents. But there is a workaround.

Step 1: Follow the above steps to compare documents.

Step 2: In the menu of the new document, click Tools, and then click Review suggested edits.

Step 3: To accept all the suggested edits at once, click Accept All. If you want to manually review each suggestion first, click either the up (∧) or down caret (∨) beside Suggested edits, and the Accept All button will automatically change to Accept. Now you can accept edits one by one.
