About the code: It copies sheet7.RangeB11 till the last used column when the word MAPPED is found in sheet7.RangeA11 and so on; paste them in the said destination.

Problem: I have large data set (around 2,00,000 lines) and this code consumes a lot of time when compared to the task implemented manually.

Could any one help me optimize this code?

VBA Code:
Sub cf()

Dim lr, lc   As Long

With Sheet7


lr = .Cells(Rows.Count, 1).End(xlUp).Row
For H = 11 To lr
    lc = .Cells(H, Columns.Count).End(xlToLeft).Column
    If .Cells(H, 1) = "Mapped" Or .Cells(H, 1) = "mapped" Then
      .Range(.Cells(H, 2), Cells(H, lc)).Copy
    Sheet3.Cells(Rows.Count, 2).End(xlUp).Offset(1, 0).PasteSpecial xlPasteValues

End If

Next


End With
End Sub
 

Excel Facts

Using Function Arguments with nested formulas
If writing INDEX in Func. Arguments, type MATCH(. Use the mouse to click inside MATCH in the formula bar. Dialog switches to MATCH.
How about
VBA Code:
Sub HarshilMehta()
   Dim Ary As Variant, Nary As Variant
   Dim r As Long, c As Long, nr As Long
   
   With Sheet7
      c = .Cells.Find("*", , , , xlByColumns, xlPrevious, , , False).Column
      Ary = .Range("A11", .Range("A" & Rows.Count).End(xlUp)).Resize(, c).Value2
   End With
   ReDim Nary(1 To UBound(Ary), 1 To c - 1)
   For r = 1 To UBound(Ary)
      If LCase(Ary(r, 1)) = "mapped" Then
         nr = nr + 1
         For c = 2 To UBound(Ary, 2)
            Nary(nr, c - 1) = Ary(r, c)
         Next c
      End If
   Next r
   Sheet3.Range("B" & Rows.Count).End(xlUp).Offset(1).Resize(nr, UBound(Nary, 2)).Value = Nary
End Sub

End Sub
This is PERFECT. Thank you so much for your time.:love:

End Sub
Can we retain the source formatting in the output? For example: my source data contains numbers which are stored as text, however the above code coverts them into numbers in the output. I don't want the code to convert them instead retain the source formatting.
