However I am not from Autodesk, I did indeed get the same error you were getting. I ran a few tests, all with the same results except for one. I was able to copy all the cells into a new excel file, then save it. At that point you can then use the SS>plc utility. I hope this helps.
I don't know why it is choking on your spreadsheet. But the SS-->PLC I/O routine is provided in full-source format for users to customize. You can go into your copy of c:\program files\autodesk\acade 2004\support\wdio.lsp and make this change to try to bypass where the program is choking when it's reading your spreadsheet. Open with any ASCII text editor (ex: wordpad.exe). Look for this snippet of code in your copy of wdio.lsp and add in the one line as shown:
(foreach tab tabnams
(princ (strcat "\n" (c:wd_msg "SWAP030" nil "Sheet:") " "))
(setq x (wd_mdb_GetRecCount GBL_wdio_ff tab))
(if (not x)(setq x 0)) ;;; <<== add in this line
(princ (c:wd_msg "SWAP031" nil ", record count="))
(if (AND x (> x 2))
(setq tabs_with_data (cons tab tabs_with_data))
See if this resolves the your problem with your spreadsheet. If it doesn't, flip your spreadsheet's column "I" from integer numbe format to "char text".
