There are three ways for your reference:
1. Use CAD data link function. The steps: Open the [tools]>Open the [Data Connection]>Create a new Excel data connection> Define the connection name > Click OK and open the file you want to link with. The advantage of this method is that you don’t need to change the data in the dwg file if the data in the EXCEL changes as they change jointly.
2. Copy the sheet in the Excel firstly. Open the AutoCAD and select the [CAD Entities] in the [Paste Special]dialog box under the [Edit] menu.
3. Copy the text in the Excel and Word directly into the CAD software. But you can’t edit the text in the drawing after the paste.
