How to Fix Incorrect Document Comparison Results in Word 365
Product
Microsoft Word 365
Device & OS
not provided
Scenario
Comparing an original document with a revised version to see only the newly made differences between the two files.
Observed behavior
Word displays previously tracked changes that were already present in the revised document instead of strictly showing the differences between the original and revised versions.
Before you start

Before running the comparison tool, check both your original and revised documents for any pending tracked changes by navigating to the Review tab. Resolving these unresolved edits in advance is required for an accurate side-by-side comparison.

Solution 1Recommended

Accept All Tracked Changes Before Comparing

Manually accepting all tracked changes on duplicate copies of your documents prevents Word from displaying old edits during the comparison process.

When either document contains unresolved tracked changes, Word attempts to integrate them into the comparison, often resulting in a cluttered document that shows edits already present in the revised file. By creating clean copies where all changes are accepted, you force Word to only look at the structural and textual differences between the two final states.

1
Duplicate the documents

Open your file explorer and make copies of both the original document and the revised document to protect your original tracked files.

2
Open the copied original document

Launch Word 365 and open the newly created copy of your original document.

3
Accept all changes

Navigate to the 'Review' tab on the top ribbon, click the 'Accept' dropdown menu in the Tracking group, and select 'Accept All Changes'. Save and close the document.

4
Repeat for the revised document

Open the copy of your revised document and repeat the previous step (Review > Accept > Accept All Changes), then save and close.

5
Run the document comparison

Open a blank Word document, go to the 'Review' tab, click 'Compare', and select the clean copies of your original and revised documents to view accurate differences.

Clean Comparison Results: By comparing these clean copies, Word will successfully highlight only the actual modifications made between the original and revised versions.

Frequently Asked Questions

Why does Word show old edits when I compare documents?

If either the original or revised document contains unresolved tracked changes, Word attempts to process these during the comparison, which merges old edits into the new comparison document. Accepting changes beforehand prevents this behavior.

Can I compare documents without losing the original tracked changes in my files?

Yes. Always make duplicate copies of your original and revised files in your file explorer before accepting any changes. Use these clean copies strictly for the comparison process so your original files remain untouched.

Does the 'Legal blackline' option fix the tracked changes issue automatically?

No. While the legal blackline setting is designed to show differences clearly by default, it may still prompt you to accept or reject existing tracked changes, or result in cluttered output if unresolved changes exist in the source files.
