I have a table range contains data from ColA to colG, i want to select some col inside the range and union them together to put into a array, i use below codes, but it seems vArray turns out to be contain only one col (ColA) data only, how can i change the code so that it will contain col 1, 4, 6, 7? Thanks

Code:
Sub test()
Call EquityCSV(Range("A4:G80"))
End Sub
 
Sub EquityCSV(rEquityRange As Range)
Dim rRange As Range
Set rRange = Application.Union(rEquityRange.Columns(1), rEquityRange.Columns(4), _
rEquityRange.Columns(6), rEquityRange.Columns(7))
rRange.Select
Dim vArray As Variant
vArray = rRange.Value
End Sub

If the range is non-contiguous then you need to loop thru each area within the range and write it to the array. One way you might do this is to have a holding (jagged) array the elements of which will each contain one area's worth of data (eg one column in your case):

Code:
Sub test()
Dim vHolding As Variant   'holding array

Dim rng As Range

Dim i As Long  'loop counter

Set rng = Range("C14:C30,F20:F40,K16:K43,Q40:Q42")

ReDim vHolding(1 To rng.Areas.Count)  'resize holding array to number of contiguos ranges in rng

'loop thru rng.Areas:
For i = 1 To rng.Areas.Count
    vHolding(i) = rng.Areas(i).Value   'will create an array as element i in vholding (unless single cell range)
Next i

'to access individual cells, you need to use following syntax:

MsgBox vHolding(3)(3, 1)

'to write back to ranges, need to do each element at a time:

Worksheets.Add
Range("A1").Resize(UBound(vHolding(3), 1), UBound(vHolding(3), 2)).Value = vHolding(3)

End Sub

Hi

In this case, since you have a table and want to address the intersection of rows and columns, you can also address them directly using Index(), like:

Code:
Sub test()
Dim vArray As Variant
 
vArray = EquityCSV(Range("A4:G10"))
' do something with vArray
End Sub
 
Function EquityCSV(rEquityRange As Range)
Dim vRows As Variant
 
vRows = Evaluate("row(" & rEquityRange.Address & ")-" & rEquityRange.Row & "+1")
EquityCSV = Application.Index(rEquityRange, vRows, Array(1, 4, 6, 7))
End Function
