Hi,
I am working on delete negative number in a range(in my case is in column J from row 19 to the last row with data).
as of now I use this kind of code

Code:
<code style="margin: 0px; padding: 0px; font-style: inherit; font-weight: inherit; line-height: 12px;">'delete negative data on col J
Dim LR As Long, i As Long
LR = Range("J" & Rows.Count).End(xlUp).row
For i = LR To 20 Step -1
'    If Range("J" & i).value < 0 Then Rows(i).Delete
Next i</code>


This code working fine just a little bit slow if the amount of data increase.

My question is, are there any fastest way to delete all negative number(including other data in the same row) other then the one I use above?

all your help will be greatly appreciated.

Regards,
Benny
 

Excel Facts

Why does 9 mean SUM in SUBTOTAL?
It is because Sum is the 9th alphabetically in Average, Count, CountA, Max, Min, Product, StDev.S, StDev.P, Sum, VAR.S, VAR.P.
Benny, this should be much faster if you have large data. There was a small discrepancy between your description and your code about which row to start at. I have used row 20 in my code, thinking that perhaps row 19 may be a heading. Anyway, adjust if needed. See how it goes in a copy of your workbook & let us know if there are any problems.

Rich (BB code):
Sub DeleteNegatives()
  Dim a As Variant, b As Variant
  Dim nc As Long, i As Long, k As Long, lastrow As Long
  
  With Rows("20:" & Range("J" & Rows.Count).End(xlUp).Row)  '<- Check first row of actual data
    nc = .Find(What:="*", After:=.Cells(1, 1), LookIn:=xlValues, SearchOrder:=xlByColumns, SearchDirection:=xlPrevious, SearchFormat:=False).Column + 1
    a = .Columns(10).Value  '<- Column 10 = Column "J"
    ReDim b(1 To UBound(a), 1 To 1)
    For i = 1 To UBound(a)
      If a(i, 1) < 0 Then
        b(i, 1) = 1
        k = k + 1
      End If
    Next i
    If k > 0 Then
      Application.ScreenUpdating = False
      .Columns(nc).Value = b
      .Sort Key1:=.Columns(nc), Order1:=xlAscending, Header:=xlNo, OrderCustom:=1, Orientation:=xlTopToBottom, DataOption1:=xlSortNormal
      .Resize(k).EntireRow.Delete
      Application.ScreenUpdating = True
      End If
  End With
End Sub
