This function reads data from an Excel sheet without using MS-Office

Arguments:
myXlsFile [string] The path and file name of the Excel file
mySheet [string] The name of the worksheet used (e.g. "Sheet1")
my1stCell [string] The index of the first cell to be read (e.g. "A1")
myLastCell [string] The index of the last cell to be read (e.g. "D100")

Dim arrData( ), i, j
Dim objExcel, objRS
Dim strHeader, strRange

Const adOpenForwardOnly = 0
Const adOpenKeyset = 1
Const adOpenDynamic = 2
Const adOpenStatic = 3

Define header parameter string for Excel object
If blnHeader Then
strHeader = "HDR=YES;"
Else
strHeader = "HDR=NO;"
End If

Open the object for the Excel file
Set objExcel = CreateObject( "ADODB.Connection" )
IMEX=1 includes cell content of any format; tip by Thomas Willig
objExcel.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & _
myXlsFile & ";Extended Properties=""Excel 8.0;IMEX=1;" & _
strHeader & """"

Open a recordset object for the sheet and range
Set objRS = CreateObject( "ADODB.Recordset" )
strRange = mySheet & "$" & my1stCell & ":" & myLastCell
objRS.Open "Select * from [" & strRange & "]", objExcel, adOpenStatic

Read the data from the Excel sheet
i = 0
Do Until objRS.EOF
Stop reading when an empty row is encountered in the Excel sheet
If IsNull( objRS.Fields(0).Value ) Or Trim( objRS.Fields(0).Value ) = "" Then Exit Do
Add a new row to the output array
ReDim Preserve arrData( objRS.Fields.Count - 1, i )
Copy the Excel sheets row values to the array "row"
IsNull test credits: Adriaan Westra
For j = 0 To objRS.Fields.Count - 1
If IsNull( objRS.Fields(j).Value ) Then
arrData( j, i ) = ""
Else
arrData( j, i ) = Trim( objRS.Fields(j).Value )
End If
Next
Move to the next row
objRS.MoveNext
Increment the array "row" number
i = i + 1
Loop

Close the file and release the objects
objRS.Close
objExcel.Close
Set objRS = Nothing
Set objExcel = Nothing

Return the results
ReadExcel = arrData
End Function

Option Explicit

Dim arrSheet, intCount

Read and display columns A,B, rows 2..6 of "ReadExcelTest.xls"
arrSheet = ReadExcel( "ReadExcelTest.xls", "Sheet1", "A1", "B6", True )
For intCount = 0 To UBound( arrSheet, 2 )
WScript.Echo arrSheet( 0, intCount ) & vbTab & arrSheet( 1, intCount )
Next

WScript.Echo "==============="

An alternative way to get the same results
arrSheet = ReadExcel( "ReadExcelTest.xls", "Sheet1", "A2", "B6", False )
For intCount = 0 To UBound( arrSheet, 2 )
WScript.Echo arrSheet( 0, intCount ) & vbTab & arrSheet( 1, intCount )
Next
