How to Find the Differences Between Two Documents?


Finding the differences in multiple documents requires significant scrutiny and may increase the chances of making errors. Nevertheless, finding document differences is essential to avoid version confusion. It is also necessary for job requirements in the legal, government, insurance, and education sectors. 

Just like you can use Affinda to extract information from invoices, you can use various online and desktop options to make the process straightforward. 


If you use ONLYOFFICE Workspace or ONLYOFFICE Docs, it is enough to help you compare documents. To compare a file with the one you are currently working on, navigate to the Comparison tab and find the Compare feature. From there, click the icon to browse a file, enter a URL to access files from cloud storage, or select the file from Storage (if you want to choose the document from your account). 

You should see all the differences the selected document has highlighted. Use the Next and Previous buttons if you want to navigate between changes. You may reject or accept the changes simultaneously in case you wish to merge two document versions, or you may do so in turns. 

The Display modes should help you see the differences: the Final mode shows the document with accepted changes, the Original mode previews the initial document version, and the Markup mode allows you to go back to work with the changes.

Microsoft Word’s Compare Feature

You can use Microsoft Word’s built-in Compare feature to find differences between two Word documents. From the Review tab, find and click Compare, then Compare Documents. From the Original Document, choose your original word file and on the Revised Document section, choose the document to be compared with the formerly selected document. If you want, you can specify a label for the changes and then click OK. 

The two documents are merged, and the revised document highlights the differences. You see the original document, which remains untouched, and a third version that reflects changes you can accept or reject. This allows you to avoid content duplication, which is an ideal practice for SEO-friendly writing.

Google Docs

Google’s online office is another solution that can help you find differences between Word documents. The app is free to use but is completely online-based. Google docs will, however, not be effective if you want to find differences in PDFs, PowerPoint, and Excel files. It only works with text files. 

To use you, go to Tools, then Compare Documents. You select the comparison document and specify where to attribute the differences. From there, hit Compare, wait for the process, and click Open to view.
