[TABLE="width: 179"]

Any help is appreciated. The number of rows will be dynamic but column can remain the same.[/TD]

Try this for results in columns "F & G".

[COLOR="Navy"]Dim[/COLOR] Dic [COLOR="Navy"]As[/COLOR] Object, K [COLOR="Navy"]As[/COLOR] Variant, P [COLOR="Navy"]As[/COLOR] Variant
[COLOR="Navy"]Dim[/COLOR] c [COLOR="Navy"]As[/COLOR] [COLOR="Navy"]Long[/COLOR]

Ray = Range("A1").CurrentRegion
[COLOR="Navy"]Set[/COLOR] Dic = CreateObject("scripting.dictionary")
Dic.CompareMode = vbTextCompare


[COLOR="Navy"]For[/COLOR] ac = 1 To UBound(Ray, 2) - 1
    [COLOR="Navy"]For[/COLOR] n = 2 To UBound(Ray, 1)
        [COLOR="Navy"]If[/COLOR] Not Dic.exists(Ray(n, ac)) [COLOR="Navy"]Then[/COLOR]
                [COLOR="Navy"]Set[/COLOR] Dic(Ray(n, ac)) = CreateObject("Scripting.Dictionary")
          [COLOR="Navy"]End[/COLOR] If
        [COLOR="Navy"]If[/COLOR] Not Dic(Ray(n, ac)).exists(Ray(n, ac + 1)) [COLOR="Navy"]Then[/COLOR]
                Dic(Ray(n, ac)).Add (Ray(n, ac + 1)), Nothing
        [COLOR="Navy"]End[/COLOR] If
    [COLOR="Navy"]Next[/COLOR] n
[COLOR="Navy"]Next[/COLOR] ac
   
c = 1
Cells(c, "F") = "Parent"
Cells(c, "G") = "Child"

[COLOR="Navy"]For[/COLOR] [COLOR="Navy"]Each[/COLOR] K [COLOR="Navy"]In[/COLOR] Dic.Keys
    [COLOR="Navy"]For[/COLOR] [COLOR="Navy"]Each[/COLOR] P [COLOR="Navy"]In[/COLOR] Dic(K)
        c = c + 1
        Cells(c, "F") = K
        Cells(c, "G") = P
    [COLOR="Navy"]Next[/COLOR] P
[COLOR="Navy"]Next[/COLOR] K
[COLOR="Navy"]End[/COLOR] [COLOR="Navy"]Sub[/COLOR]

Thannks the code worked.
Now what if my columns are also varying. How to tackle that?
If you could please let me know that one.

 

[subhojyoti]

What if I now want to do the reverse. The source is in two column format and the output would be multiple levels.

The original code should cover Multi columns of data.

Reversing your data is possible as below, but depending on its complexity there could be problems
Your data for reversing in "A & B" reversed results for previous data in columns "G to J".
