It was a little work but I got something I think will work. As you know AutoCAD, and in turn scripts, are sensitive to the use of space characters. Several of the attribute values you use have space characters. In addition, it is somewhat tricky to get single " marks with the Excel concatenate command. I therefore found it easiest to use the VLISP command command to generate a satisfactory command that could handle the quotes and spaces and that can be entered at the command prompt. I used CHAR(34) in Excel to generate a single ". To get around the fact that some attribute values include space characters I placed quotes around them. I hope this does not cause a problem. There may be another way to deal with this probably with VLISP but I didn't want to get into writing a full VLISP program.
To use the Excel file just copy the contents of the K column to the Windows clipboard (Ctrl-C). At this point you can paste to the command line in AutoCAD or paste to Notepad (I use Notepad ++) and save the file as a txt file but with the file extension .scr. You can then run the resulting script in AutoCAD.

Here's the contents of cell K2:
=CONCATENATE("(command ",CHAR(34),"-insert",CHAR(34)," ",CHAR(34),A2,CHAR(34)," ",CHAR(34),I2,",",J2,CHAR(34)," 1 1 0 ",CHAR(34),B2,CHAR(34)," ",CHAR(34),C2,CHAR(34)," ",CHAR(34),D2,CHAR(34)," ",CHAR(34),E2,CHAR(34)," ",CHAR(34),F2,CHAR(34)," ",CHAR(34),G2,CHAR(34)," ",CHAR(34),H2,CHAR(34),")")
It generates an AutoCAD command that looks like this:
(command "-insert" "Socket_Circtuit_Ref" "0,0" 1 1 0 "1A/1L1" "A" "1" "1" "TYPE A" "Inactive" "A 1")
There is probably some streamlining that could be done but I think the approach is valid.
Note, you should turn off OSNAP before running the program. This can be done manually before you run the program or via the command: (setvar "osmode" 0)
