I hesitate with "Excel table". I have mostly avoided Excel, and work in open office.
But, if you can get your file to export in csv format, I can show you how to read that into Autocad.
A simple spread sheet I have done. Tables mean other things to me in other languages, and I become uncertain.
Export to csv, and you will have a pure text file, delineated with commas, and lisp can read it line by line,
parse for commas, and draw whatever lines, or insert block, or whatever, depending on what the geometry
in the spread sheet means.
