How can I tell excel to highlight every 4 rows?

[Amanda]

I need to highlight every 4 rows in my spreadsheet. How do I do this? I
have 21000 rows to sort through.

One way
Sub HI()
For I = 1 To 21000 Step 4
Rows(I).Interior.ColorIndex = 6
Next I
End Sub

Can also be done using conditional formatting with...

Formula Is =MOD(INT((ROW(1:1)-1)/4),2)=0

which applies the chosen highlight colour to the 1st to 4th, 9th to
12th etc rows in the cells that were selected before the conditional
formatting was applied,OR...

Formula Is =MOD(INT((ROW(1:1)-1)/4),2)=1

which applies the chosen highlight colour to the 5th to 8th, 13th to
16th etc rows in the cells that were selected before the conditional
formatting was applied.
