In the AutoCAD command box, type "TABLE" to start the command.
Select the "From A Data Link" option and click the "Data Link Manager" icon. These options can be found under "Insert Options."
Click "Create A New Excel Data Link" and type in a name for the link. Organizing by name is essential, so make sure that you name the link properly.
Browse through your computer and select the file you wish to import. You can only select one Excel file at a time.
Open up "Data Link Options" and click "Cell Contents." Uncheck the "Convert Data Types To Text" icon but check "Retail Formulas" and "Allow Writing To Source File." This will ensure that the original Excel file remains.
Click "OK" to exit the dialog boxes and then insert the table in your AutoCAD drawing. Click on the drawing to select an insertion point. Follow the remaining commands.
