If the content of another Word document is related to the content of the Word document you may be working on, you can embed the text of that document into the current document you are editing. To do this, you will need to follow a few simple steps.
First, open the Word document to which you want to add the contents or embed another Word document.
Then, go to the “Text” group of the “Insert” tab and click the down arrow next to the “Object” option .

A drop-down menu will appear . There are two options to choose from here: “Object” and “Text from file” .
Object : Embeds an object such as a Word document or an Excel chart Text from File : Inserts text from another file into the Word document
The “Text from File” option is essentially a faster way to copy and paste the contents of another file into this one.
Try it out by clicking on the “Text from file” in the drop-down menu.

This will open File Explorer (Finder on Mac). Find the file you want to copy the text from, select it, and then click “Insert”.

The contents of that Word document will now appear in the current Word document. This works well if there isn't much content in the other Word document, but if there is, embedding it may be a better option.
Back in the “Object” drop-down menu (Insert > Text group > Object) click on the “Object”.

You will see the “Object” window . Select the “Create from File” tab , then click “Browse.” The “Create from File” option will appear as a button in the lower-left corner of the window on a Mac.

You'll be taken to File Explorer (Finder on Mac). Find the file you want to embed, select it, and then click “Insert.

The file path of the selected file will now appear in the text box next to “Search”. Now, you need to decide how you want to import the object. You have two options:
Link to File: Inserts the contents of the selected file into your Word document and creates a link back to the source file. Changes made to the source file will be reflected in your document. Selecting “Link to File”will insert the contents of the other file into a text box.
Show as Icon: Inserts an icon to indicate to the reader that an embedded object is present. This is ideal when space is at a premium.
We will check both options in this example.

The file will be embedded in the Word document. Double-clicking the icon will open the second Word file.
One caveat with this method is that moving the source file will break the link to the embedded object. For this reason, Microsoft prevents you from moving the source file to a different location. If you try to do so, you will receive the following message:

Finally, if you need to move the source file to another location, you will need to remove the embedded link, move the source file, and then re-embed the file, following the steps we mentioned above.
