Needs macros to delete row ranges in excel

I would like to delete a range of rows, but not the top row,  that are missing a string in a certain column.

In this particular question I am looking for all of the latest Android Marshmallow devices where are identified by the string "Linux; Android 6.0.1;" in column W. The row header is "USER_AGENT" and I don't want to delete that one either.  

All other rows are to be deleted.

This is a huge spread sheet (65000 rows+) and I don't want to do this manually.

Thanks,

Chris

try this on a copy.

Sub test()
With ActiveSheet
    .AutoFilterMode = False
    With Range("W2", Range("W" & Rows.Count).End(xlUp))
        .AutoFilter 1, "*Linux; Android 6.0.1;*"
        On Error Resume Next
        .Offset(1).SpecialCells(12).EntireRow.Delete
    End With
    .AutoFilterMode = False
End With
End Sub

Won't this one delete the top row (the header) which contains the text "USER_AGENT" but not "*Linux; Android 6.0.1;*"?

Sub test()
With ActiveSheet
    .AutoFilterMode = False
    With Range("W2", Range("W" & Rows.Count).End(xlUp))
        .AutoFilter 1, "*Linux; Android 6.0.1;*"
        On Error Resume Next
        .Offset(1).SpecialCells(12).EntireRow.Delete
    End With
    .AutoFilterMode = False
End With
End Sub

Please try this....(Before trying this, create a backup of your data)
Sub DeleteRows()
Dim lr As Long
Application.ScreenUpdating = False
lr = ActiveSheet.UsedRange.Rows.Count
With Range("W1:W" & lr)
   .AutoFilter field:=1, Criteria1:="<>*Linux; Android 6.0.1;*"
   If Range("W2:W" & lr).SpecialCells(xlCellTypeVisible).Cells.Count > 1 Then
      Range("W2:W" & lr).SpecialCells(xlCellTypeVisible).EntireRow.Delete
   End If
   .AutoFilter
End With
Application.ScreenUpdating = True
End Sub

It seems like I was not specific enough. My apologies.

I want to delete rows that are missing these two strings in Col W.

USER_AGENT and Linux; Android 6.0.1;

"...  that are missing a string in a certain column."

It seems the solutions thus far delete the rows that contain  Linux; Android 6.0.1;

I want the "NOT" of that operation

Did you try the code I suggested in Post ID: 41761228?
I think that does what you are trying to achieve.

ID: 41761229 actually deleted every line that contained "*Linux; Android 6.0.1;*"in column W.

I didn't mention at first that I am running on a MAC book because I did not think it significant: would these functions run differently on a PC vs MAC?

Well that shouldn't be the case.
The code is assuming that row1 is the header row and the actual data starts from row2.
Can you upload a small sample workbook to work with (max 50 rows) and highlight the cells in col. W that need to be deleted?

How about if I just extract column W? What is in that column is fairly generic and not proprietary---but most of the 52 columns are proprietary and I would need to obfuscate them.

That's completely fine.
Just show what's there in col. W and highlight the cells which needs to be deleted.

This took a while: this is a sheet with 30,000 + rows and 55 columns and I wonder if the size made a difference.

The rows to be deleted are in purple.

49      Mozilla/5.0 (Linux; Android 6.0.1; D6503 Build/23.5.A.1.291; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/52.0.2743.98 Mobile Safari/537.36

this is the portion of the string I care about: "Linux; Android 6.0.1; "

If you can't duplicate this issue with this smaller spread sheet, I may need to upload a larger one.

Please find the attached and click the button on Test Sheet to run the code and let me know if the code does what you are trying to achieve.
It contains the same code posted in the Post ID: 41761228.

Hmmmmm.

This works on my PC but not my Mac Book.

There must some functional difference between Excel on MAC and Excel on my PC.

I'll need to retest all the suggestions on my PC tonight

I am not sure why, but your solution works perfectly on Excel running on my PC but does not work when running Excel on my Mac Book.

Can you try the following code to see if that works on your Mac also?

Sub DeleteRows()
Dim lr As Long
Application.ScreenUpdating = False
lr = ActiveSheet.UsedRange.Rows.Count
With Range("W1:W" & lr)
   .AutoFilter field:=1, Criteria1:="<>*Linux; Android 6.0.1;*"
   If Range("W1:W" & lr).SpecialCells(xlCellTypeVisible).Cells.Count > 1 Then
      Range("W2:W" & lr).SpecialCells(xlCellTypeVisible).EntireRow.Delete
   End If
   ActiveSheet.ShowAllData
End With
Application.ScreenUpdating = True
End Sub
