Looping Macro That adds a blank row between different part #'s

I do several reports everyday that require me to put a blank row between part
numbers that are different.

So, I'd like a Macro that would compare two cells, if they are equal to each
other, do nothing but keep moving down the list and comparing. If the cells
are different, one part number might be 100200 and the other part number
might be 655422, then put a blank row between those two parts and move on to
compare the rest of the list.

I'm pretty good with Excel and formulas - just new to working with Macros -
but am finding out they are pretty similar... just not sure of the correct
commands...

All I need is to see an example...

Many Thanks!!!

Option Explicit

Sub a()

Dim i As Long 'Not Integer because it could grow > 32768

Sheets("Sheet1").Select
i = 2
Do While Not IsEmpty(Cells(i, 1))
If Cells(i - 1, 1).Value <> Cells(i, 1).Value Then
Range("A1").Offset(i - 1).EntireRow.Insert
i = i + 1
End If
i = i + 1
Loop

End Sub

Operating on chosen column.

Sub InsertRow_At_Change()
Dim i As Long
Dim colno As Long
With Application
.Calculation = xlManual
.ScreenUpdating = False
End With
colno = InputBox("Enter a Column Number")
For i = Cells(Rows.Count, colno).End(xlUp).Row To 2 Step -1
If Cells(i - 1, colno) <> Cells(i, colno) Then _
Cells(i, colno).Resize(1, colno).EntireRow.Insert
Next i
With Application
.Calculation = xlAutomatic
.ScreenUpdating = True
End With
End Sub

This WORKED PERFECTLY!!! You are an absolute Genius!!! Thank you! Thank
you! Thank you!!!

I couldn't find a way to make it work with my header row, so I just cut and
pasted my header row to the end of the sheet and when I was done, just cut
and pasted them back to the top row. Other than that, I just filled in the
name of my "Sheet1" tab and presto!!!! Thanks again!!! You have just saved
me and my boss and my company hours of labor.

Thank you for replying! I received another solution from a "Bernd Plumhoff"
that was a little bit shorter than your example and it did what I needed.

But, I REALLY appreciate you taking the time to answer. I'm sure yours
would have worked as well.

You are welcome.

If only one specific header has to be ignored, change:
....
If Cells(i - 1, 1).Value <> Cells(i, 1).Value Then
....
to

If (Cells(i - 1, 1).Value <> Cells(i, 1).Value) and _
Left(Cells(i, 1).text,20)<> "First 20 Chars of Header Row" Then

for example (if you have to cross that bridge again).

HTH,
