Hi Experts, I think this an easy one, but I'm having trouble figuring it out... I have a one dimension array with about 500,000 values that I need to dump into an excel column quickly.  I'm currently using the code:
For x = 1 To UBound(N_Data)
        Cells(x + 1, Last_Col) = N_Data(x)
Next x

Open in new window

Unfortunately this is very slow.  When I try to simply select the range and set the value equal to my data i.e.:
Range(Cells(2,Last_Col),Cells(Ubound(N_Data)+2),Last_Col)) = N_Data

Open in new window

it dumps blank values.  I think this is because the values in my array need to be transposed...

You need to transpose the array

Dim xdata(9) As Integer

xdata(5) = 5

Range("a1:a10") = Application.Transpose(xdata)

puts a column of zeroes with row 6 = 5 (array is zero based)

Thanks, that seems like it should work, but when I try to apply it I keep getting a Run time error "13" Type Mismatch...  any thoughts?

Range(Cells(2, Last_Col), Cells(UBound(N_Data) + 1, Last_Col)) = Application.Transpose(N_Data)

See my Fast Data Push to Excel article:

You need to create a 2D array, not a 1D (vector) data structure.

Perfect - that did the trick.  I added a dimension to my array
ReDim N_Data(UBound(R_Data), 1)

Open in new window

Loaded my data into the "0" dimension (starting in the "0" position)
For x = 1 To UBound(R_Data, 1)
     N_Data(x - 1, 0) = 'insert calculated value here
Next x

Open in new window

Then bulk-wrote the results
Last_Col = Cells(1, 100).End(xlToLeft).Column
Range(Cells(2, Last_Col), Cells(UBound(N_Data, 1) + 1, Last_Col)) = N_Data

Open in new window
