help with getting data from excel then replacing variable using the data

Hello AutoIt community,

i would like to ask your help to my problem with getting the data from excel then replace a variable with the data.

I have an excel file in which the data resides, i would like to replace some variables based on the data i got from the excel file.

i would like to ask if there is someone willing to help me in private, i would give him/her the project i'm doing

Here's so far what i have

Func database()
$oExcel = _ExcelBookOpen("C:\sample.xls", 0, True)
Global $iLine = 2
While 1
Global $aArray = _ExcelReadArray($oExcel, $iLine, 1, 4, 0)
If $aArray[0] = "" Then Exit ; Empty line detected - exit
$iLine += 1
;MsgBox(0,$aArray[0],$aArray[1] & @CRLF)
WEnd
EndFunc

TIA
