How to merge and modify Word documents after comparing them

Explain how to accept or reject revisions after comparing Word documents, merge the two versions into a final draft, and explain how to clear comparison marks, comments and hidden information, with an item-by-item checklist.

Key points of this article

  • The comparison results take the original document as the starting point. If you accept all revisions, you will get the content of the revised document. If you reject it, the original document will be returned. You need to think clearly about both before proceeding.
  • Save a copy before starting, and deal with the original outstanding revisions of the two documents, otherwise the comparison results will be mixed with the old revisions.
  • When checking revisions item by item, numbers, dates, clause numbers and references must be verified against the original manuscript, not just whether the format is neat.
  • Removing contrast markers requires accepting or rejecting all revisions, cleaning up comments, and turning off revision tracking before issuing the file.

The two Word documents are revised back and forth, and there will soon be several versions: the colleague changed the wording in the second version, you added the table in the third version, and the leader rewrote the conclusion paragraph. You can use Word's document comparison function to highlight the differences, but highlighting is only the first step. What really makes readers stuck is that after the comparison is completed, the screen is full of strikethroughs, underlines and revision boxes. They don’t know which ones should be kept and which ones should be removed, let alone how to get a clean final draft.

This article is written for people who need to consolidate multiple revised drafts into one, such as when contract terms are revised back and forth, the paper is revised after being commented by the instructor, or a team collaborates to write a report. After reading, you will be able to judge how to handle each modification in the comparison results, keep only the desired version, what checks to do after merging, and how to completely clear the comparison marks. The operations in this article are based on the general functions of Word and do not rely on the specific menu of a certain software.

How to merge and modify after comparison? One sentence conclusion

If the second document is a new version that you want to keep and most of the modifications need to be adopted, then you can accept all the revisions in the comparison results; if only some modifications are to be retained, you need to judge them one by one. The key is to decide which one to base on before taking action.

The second document is a new version, and all modifications must be basically retained.Set the new version as a revised document, accept all revisions and read through itThe comparison result takes the original document as the starting point, and after acceptance, it becomes the new version.
There are only a few parts that I want to keep, and the rest I want to return to the old manuscript.Check the revisions item by item, accept what you want, and reject what you don’t.This prevents the entire paragraph from being mistakenly changed and keeps the changes you have confirmed.

Before you start: Confirm these points first

Before taking action, take a few minutes to make these judgments to avoid discovering that the direction is wrong halfway through merging.

  • Determine which copy is the original copy and which copy is the new version. The comparison results show the changes from the original document to the revised document. If the direction is reversed, the meaning of acceptance and rejection will be completely reversed. The deleted content will be regarded as new, and the new content will be deleted instead.
  • Confirm that the two documents are different versions of the same manuscript. If the two documents are actually two independent pieces of content, the comparison result will be filled with deletions and additions, making it difficult to process them one by one. At this time, it is more suitable for manual sorting rather than forced comparison.
  • Process the original revisions and comments of the two documents. If the manuscript already contains unprocessed revisions, they will be mixed with the results of this comparison. It is recommended to accept or reject the original revision first, and then compare.
  • Save a copy as a working document. The original two documents remain unchanged, the merge process only takes place on the copies. If you make a mistake, you can start over from the original.
  • Mark the content that needs to be checked. The amount, time limit, clause number in the contract, and the data, quotations and chart numbers in the paper should all be compared with the original manuscript one by one after merging. Don't just look at whether the layout is neat.

Steps to merge comparison results into final draft in Word

The following steps are based on the general functions of Word. When operating, just find the corresponding entrance according to the version of Word at hand.

  1. Save a copy. Save a separate copy of the earlier document and the newer document as input for comparison, without any changes to the original document.
  2. Start document comparison. Find the document comparison function in Word and select the earlier version as the original document and the newer version as the revised document.
  3. Generate comparison results. After the comparison is complete, Word will generate a new document with revision marks showing new additions, deletions, and formatting changes.
  4. Open the review pane. Browse all revisions in order in the pane, which lists the location and content of each change for easy processing one by one.
  5. Accept or reject each item. Accepting means adopting the revised content, rejecting means returning the original text. For uncertain changes, keep them and mark them first, and then make a decision after verification.
  6. Read the full text. After all revisions are processed, read it from beginning to end, paying attention to whether the paragraph cohesion, numbering and context are smooth, because it is easy to overlook the relationship between paragraphs when processing them one by one.
  7. Clean up comments and residual marks. Delete comments that are no longer needed, confirm that there are no remaining revision marks in the text, and refer to the method in the next section to turn off revision tracking.
  8. Save as final draft. Save the final version as a new file with "Final Draft" and the date in the file name to distinguish it from the working document to avoid confusion in the future.

Check each item after completion

After you get the final draft, don’t rush to send it out. Check it through the list below.

Check itemsWhat do you think?What if there's a problem?
Revision markThere are no remaining revisions in the review pane, and there are no delete lines and underscores in the bodyFind the remaining revisions and accept or reject them one by one
AnnotationThe list of comments is empty, or there are only instructions that need to be retainedDelete useless comments, rewrite comments that need to be retained into the text or file separately
Numbers and datesCheck the amount, time limit and version number against the key paragraphs of the two manuscriptsGo back to the corresponding revision and re-judge it, and if necessary, change it back to the original.
Terms and numbersCheck whether the clause serial number, chart number and cross-reference are coherentManually correct the number and check the quotation text in the text
Format and layoutCheck heading levels, page numbers, table borders, and paragraph spacingDisordered format is often due to copying paragraphs into other styles, and reapplying them with the original style of the document.
Machine translation or OCR contentIf one of the documents comes from translation or identification, the important content should be compared with the original sentence by sentence.Directly correct the inaccuracies and retain the key expression of the original text in the final draft

# frequently asked questions (FAQ)

1. What's the difference between accepting all amendments and accepting them one by one?

Accepting all revisions will adopt all the changes in the comparison results at once, fast but unable to distinguish the details. If you accept each item one by one, you can judge each change separately, which is suitable for situations with more changes and different importance in different places.

2. Can you still find the deleted content in the comparison result?

If the deletion has not been accepted, the original text can be restored by rejecting the corresponding amendment. If you have accepted and saved it, you need to copy it back from the original, so it is important to keep a copy before you start.

3. If the paragraph order of the two documents is different, will the comparison result be messy?

Yes. When a paragraph is moved, the comparison usually appears to delete one place and add another place, and the result appears to be a lot more than the actual change. It is recommended to unify the chapter structure of the two documents, or compare them separately.

4. Can the comparison results be sent out directly as the final manuscript?

It is not recommended to send it directly. It is necessary to check, clean up the comments and hide the information one by one, and confirm that the figures, dates and terms are correct, and then save and send them as the final draft.
