Delete rows that don't match data from a list

[jimgima]

Let's say that I have two sheets on a spreadsheet.

Sheet1 has tons of data. In Column E of sheet1 are numbers that represent course numbers. I only want the data from 10 course codes to be listed (but there are hundreds on the spreadsheet).

On Sheet2 if I create a list of the course codes I want to be listed on Sheet1. Can I create a script to delete all of the rows that don't match the data on Sheet2?

Sheet2 only has one column of data. The data is in Column A. It lists the course code numbers that I want to keep?

I'd like to be able to add and delete numbers from Sheet2.

Sheet1 will be populated with new data everyweek. Most of that data is crap, so that is why I want to delete the unwanted information.

Is this enough information? Thanks for your help.

Jim

Think this should work.

If you have headings on your sheet 1 then change to for i = 1 to for i = 2

Sub RemRows()

Dim lRowA As Long
Dim lRowB As Long

Dim wsA As Worksheet
Dim wsB As Worksheet

Set wsA = Sheets("Sheet1")
Set wsB = Sheets("Sheet2")

lRowA = wsA.Range("E65336").End(xlUp).Row
lRowB = wsB.Range("A65336").End(xlUp).Row

For i = lRowA To 1 Step -1

    On Error Resume Next
        
        If wsB.Range("A1:A" & lRowB).Find(wsA.Range("E" & i).Value).Value = "" Then
        
        wsA.Rows(i).Delete
        
        End If
Next i

End Sub

Hope it helps

Thanks

I'll try this as soon as I get to work. BTW I do have headings, so I'll follow your advice. Thanks again.

Slight edit,

I meant to say, as you have headings substitute:

For i = lRowA To 1 Step -1

for

For i = lRowA To 2 Step -1

Thanks

Wow

That takes a long time to run. But, that's OK. I have a few ideas of how to make it run faster.

Here is the problem. I do have header rows. When I change

For i =1RowA To 1 Step -1

to

For i = 2RowA to step 1 -1

Am I missing something. I get a compile error: Expected: To

I'm a VB virgin.

Thanks.
