This article has been archived. It is offered "as is" and will no longer be updated.
In Microsoft Visual Basic for Applications, you can create a custom function that will turn a nonadjacent selection of cells into an array. This is useful with many of the built-in Microsoft Excel functionsthat require a single range or an array as input when the data on the worksheet is not contained in a contiguous range.

Sample Visual Basic ProcedureThis MakeArray function can use any contiguous range of cells as its arguments. Nonadjacent ranges are separated by commas.
Function MakeArray(ParamArray CellAddress()) As Variant ' Declaration of function variables. Dim Temp As Variant Dim TheArray() As Variant Dim Count As Integer, Ver as Integer Dim W As Integer, X As Integer, Y As Integer, Z As Integer ' Initialize the Count variable. Count = 1 ' Set the variable Ver = 0 if the version of Microsoft Excel is ' greater than 8 (8 is Microsoft Excel 97 for Windows). If Left(Application.Version, Len(Application.Version) - 1) >= 8 Then Ver = 0 Else Ver = 1 End If ' Set variable X from Ver to the total number of arguments in ' the CellAddress array. For X = Ver To UBound(CellAddress, 1) ' Temp equals the first element of the CellAddress array. Set Temp = CellAddress(X) ' Test Temp to see whether it is an array. If IsArray(Temp) Then ' If Temp is an array, set Y from 1 to the total number ' arguments in the Temp array's first dimension. For Y = 1 To UBound(Temp.Value, 1) ' If Temp is an array, set Z from 1 to the total number ' arguments in the Temp array's second dimension. For Z = 1 To UBound(Temp.Value, 2) ' ReDimension TheArray, Preserving any existing ' values, from 1 to Count. ReDim Preserve TheArray(1 To Count) ' TheArray, element Count equals Temp, element Y in the ' first dimension by element Z in the second dimension. TheArray(Count) = Temp(Y, Z).Value ' Increment the Count variable by one. Count = Count + 1 Next Z Next Y ' If Temp is not an array, proceed from here. Else ' ReDimension TheArray, preserving any existing ' values, from 1 to Count. ReDim Preserve TheArray(1 To Count) ' TheArray element Count equals Temp. TheArray(Count) = Temp ' Increment the Count variable by one. Count = Count + 1 ' End the block If statement. End If Next X ' Return TheArray to our function MakeArray. MakeArray = TheArrayEnd Function
Using The Sample Procedure
- Start a new Excel workbook and enter the following information in a worksheet:
A1: 1 B1: 2 D1: 5 A2: 3 B2: 4 D2: 6
- Start the Visual Basic Editor (Press ALT+F11)
- On the Insert menu, click Module.
- Type the sample Visual Basic MakeArray function code (shown above) into the module.
- Return to the worksheet (Press ALT+F11)
- On the worksheet, select cells A4:F4, type the following formula into the Formula bar=MakeArray(A1:B2,D1:D2)and then press CTRL+SHIFT+ENTER to enter the formula as an array formula.
A4:1 B4:2 C4:3 D4:4 E4:5 F4:6
