How to merge Word documents
Office 365 ProPlus is being renamed to Microsoft 365 Apps for enterprise. For more information about this change, read this blog post.
If you have to combine separate Microsoft Word documents, you can copy and paste them together if they're short, or merge them if they're long.
The following method applies to both Word 2010 and Word 2007. The format might not stay the same when you merge documents.
Select the Insert tab.
Select Object, and then select Text from File from the drop-down menu.
Select the files to be merged into the current document. Press and hold Ctrl to select more than one document.
Documents will be merged in the order in which they appear in the file list. To use a different order, select and insert each file individually in the desired order.
