    you can read/write "vlaue2" property of Excel range vla-object and then conver data between the variant and VL list. This will have a same speed as VB do.

    You can go to http://www/ to download VLXLS.
    There is a sample file to show the data exchanged between ACAD and Excel

    Following is a very simple to conver Excel data into VL list:

    First of all, please load VLXLS.LSP (or vlxls-* functions will not work) and make sure an Excel session with data is opened and set as current active spreadsheet. The codes below will convert all Excel data into VL List

    (vlxls-app-init) ;;;Initialize Link between Excel/ACAD
    (setq *xl* (vlax-get-object "Excel.Application")) ;;; Get the Excel VLA-Object
    (if *xl* (setq Range (vlxls-sheet-get-usedrange *xl* nil))) ;;; Get all used range vla-object
    (if Range (setq value (vlax-get-property Range "Value2") ;;; Get the variant value
    value (vlxls-variant->list value) ;;; Convert Variant into VL list
    (vlax-release-object range)
    (vlax-release-object *xl*) ;;; Release the vla-object

    The return value is a two dimension list, similia format is
    '(("" "" "" "")
    ("" "" "" "")
    ("" "" "" "")
