I currently have this data in a sheet
Col A Col B Col C
1 A angry birds, gaming
2 B nirvana,rock,band
What I wa
This will do what you want.

Const ANALYSIS_ROW As String = "C"

Dim iRow As Long
Dim lastrow As Long

Dim iSize As Long
'Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
With ThisWorkbook
.Worksheets("Sheet1").Copy After:=.Worksheets("Sheet1")
Set ws = ActiveSheet
End With
With ws
lastrow = .Cells(.Rows.Count, ANALYSIS_ROW).End(xlUp).Row
End With
For iRow = lastrow To DATA_START_ROW Step -1
iSplit = Split(ws.Cells(iRow, ANALYSIS_ROW).Value2, ",")
iSize = UBound(iSplit) - LBound(iSplit) + 1
If iSize = 1 Then GoTo Continue
ws.Rows(iRow).Copy
ws.Rows(iRow).Resize(iSize - 1).Insert
For iIndex = LBound(iSplit) To UBound(iSplit)
ws.Cells(iRow, ANALYSIS_ROW).Offset(iIndex).Value2 = iSplit(iIndex)

If you have a substantial amount of data, you willfind working with arrays beneficial.
Sub Macro2()
Dim i As Long, j As Long, rws As Long
Dim inp As Variant, outp As Variant
With Worksheets("sheet2")
inp = .Range(.Cells(1, "A"), .Cells(.Rows.Count, "C").End(xlUp)).Value2
For i = LBound(inp, 1) To UBound(inp, 1)
rws = rws + UBound(Split(inp(i, 3), ",")) + 1
Next i
ReDim outp(1 To rws, 1 To 3)
rws = 0
For i = LBound(inp, 1) To UBound(inp, 1)
For j = 0 To UBound(Split(inp(i, 3), ","))
rws = rws + 1
outp(rws, 1) = inp(i, 1)
outp(rws, 2) = inp(i, 2)
outp(rws, 3) = Trim(Split(inp(i, 3), ",")(j))
Next j
Next i
.Cells(1, "A").Resize(UBound(outp, 1), UBound(outp, 2)) = outp

This is the answer I have for a two column data. But I want to do it for three columns, Can someone help me here?
You are better off using variant arrays rather than cell loops - they are much quicker code wise once the data sets are meaningful. Even thoug the code is longer :)
This sample below dumps to column C and D so that you can see the orginal data. Change [c1].Resize(lngCnt, 2).Value2 = Application.Transpose(Y) to [a1].Resize(lngCnt, 2).Value2 = Application.Transpose(Y) to dump over your original data
[Updated with regexp to remove any blanks after , ie ", band" becomes "band"]
Sub SliceNDice()
Dim objRegex As Object
Dim X
Dim Y
Dim lngRow As Long
Dim lngCnt As Long
Dim tempArr() As String
Dim strArr
Set objRegex = CreateObject("vbscript.regexp")
objRegex.Pattern = "^\s+(.+?)$"
'Define the range to be analysed
X = Range([a1], Cells(Rows.Count, "b").End(xlUp)).Value2
Redim Y(1 To 2, 1 To 1000)
For lngRow = 1 To UBound(X, 1)
'Split each string by ","
tempArr = Split(X(lngRow, 2), ",")
For Each strArr In tempArr
lngCnt = lngCnt + 1
'Add another 1000 records to resorted array every 1000 records
If lngCnt Mod 1000 = 0 Then Redim Preserve Y(1 To 2, 1 To lngCnt + 1000)
Y(1, lngCnt) = X(lngRow, 1)
Y(2, lngCnt) = objRegex.Replace(strArr, "$1")
Next
Next lngRow
'Dump the re-ordered range to columns C:D
[c1].Resize(lngCnt, 2).Value2 = Application.Transpose(Y)
End Sub
This is not a polished solution, but I need to spend some time with the wife.
But still another way of thinking about it.
This code assumes that the sheet is called Sheet4 and the range that needs to be split is col C.
Dim lastrow As Integer
Dim i As Integer
Dim descriptions() As String
With Worksheets("Sheet4")
lastrow = .Range("C1").End(xlDown).Row
For i = lastrow To 2 Step -1
If InStr(1, .Range("C" & i).Value, ",") <> 0 Then
descriptions = Split(.Range("C" & i).Value, ",")
End If
For Each Item In descriptions
.Range("C" & i).Value = Item
.Rows(i).Copy
.Rows(i).Insert
Next Item
.Rows(i).EntireRow.Delete
Next i
End With
