The Advanced screen on the Word Options dialog box displays. To change this default, and paste plain text without formatting automatically when using Ctrl + V, click Paste in the Clipboard section of the Home tab and select Set Default Paste. If you want to use Ctrl + V to paste text, the text will be pasted with the formatting by default. To manually paste text without formatting, you can click Paste in the Clipboard section of the Home tab and select the Keep Text Only option. We will show you how to change the paste settings so anything pasted into Word will only be pasted as plain text.
You can choose to only keep the plain text every time you paste however, this can be annoying to do manually every time. This formatting most likely does not match the rest of the content of your document and may not come in neatly. By default, when you paste text copied from elsewhere into Word, you automatically get all the formatting with it.
