Hi, I have thecode below which splits 24 hourly prices into 48 half hourly periods. Iwould like to do something similar whereby I take a daily figure and split thisinto 48 half hourly periods. I have tried altering it in different ways but nosuccess. Any ideas? Thanks for your help.
Column A = Date
Column B = Period
Column C = Price


Sub Split_Periods_v2()
Dim a As Variant, b As Variant
Dim i As Long, p As Long

a = Range("A2", Range("C" & Rows.Count).End(xlUp)).Value
ReDim b(1 To 2 * UBound(a), 1 To 3)
For i = 1 To UBound(a)
b(i * 2 - 1, 1) = a(i, 1): b(i * 2 - 1, 2) = i * 2 - 1 - p: b(i * 2 - 1, 3) = a(i, 3)
b(i * 2, 1) = a(i, 1): b(i * 2, 2) = i * 2 - p: b(i * 2, 3) = a(i, 3)
If i Mod 24 = 0 Then p = i * 2
Next i
Range("D2").Resize(UBound(b), 3).Value = b
Range("D1:F1").Value = Array("Date", "Period", "N2EX")
End Sub
 

Excel Facts

Remove leading & trailing spaces
Save as CSV to remove all leading and trailing spaces. It is faster than using TRIM().
Lacking an examples of valid input data and their desired output, I made a best guess of what I believe you wanted:

Code:
Sub Split_Periods_v2()
    'For each data set in columns A:C, starting in row 2
    'A = Date
    'B = Period (ignored)
    'C = Amount
    'Replicate each row's data 48 times in column D:F with
    '  column E repeating counts from 1 to 48
    

    Dim a As Variant, b As Variant
    Dim lbIndex As Long, p As Long
    Dim lSplitIndex As Long
    
    a = Range("A2", Range("C" & Rows.Count).End(xlUp)).Value
    
    ReDim b(1 To 48 * UBound(a), 1 To 3)
    
    For lbIndex = 1 To UBound(a)
        For lSplitIndex = 1 To 48
            b((lbIndex - 1) * 48 + lSplitIndex, 1) = a(lbIndex, 1)
            b((lbIndex - 1) * 48 + lSplitIndex, 2) = lSplitIndex
            b((lbIndex - 1) * 48 + lSplitIndex, 3) = a(lbIndex, 3)
        Next lSplitIndex
    Next lbIndex
    Range("D2").Resize(UBound(b), 3).Value = b
    Range("D1:F1").Value = Array("Date", "Period", "N2EX")
    
End Sub
