Conditional Loop in VBA - excel

Looking for a conditional looping, perhaps Do Until or some similar that will run through the range of cells (say A3:A13) and if there’s a blank cell within that range there would be a command that will automatically hide entire row where the blank cell sits.(if the blank cell is A5 this mean entire row 5 would be hidden) The command will run through until all the the blank cells are detected and automatically all the rows associated with blank cells are hidden until it reach the end of the range A13. Any suggestions kindly welcome.

You can try something like this. First we loop through the range("A" & LRow) it will map all the blank cells and hide all in one go.
Option Explicit
Sub HideRows()
Dim ws As Worksheet
Dim LRow As Long
Dim HideRng As Range
Dim i As Long
Set ws = ActiveSheet
With ws
LRow = .Range("A" & .Rows.Count).End(xlUp).Row
For i = 2 To LRow
If Len(Trim(.Range("A" & i).value)) = 0 Then
If HideRng Is Nothing Then
Set HideRng = .Rows(i)
Else
Set HideRng = Union(HideRng, .Rows(i))
End If
End If
Next i
If Not HideRng Is Nothing Then HideRng.EntireRow.Hidden = True
Set HideRng = Nothing
End With
End Sub

AutoFilter Function is Deleting my Column Headers

I run my VBA code and the first time it runs I get the result I want but if I run it a second time my column headers get deleted. FYI my table starts on E and goes through N. My button is on column O and also gets deleted when I run it a second time.
Switching the Range did not help and setting AutoFilter to false also did not work.
#
Sub Auto_filter()
Dim sh As Worksheet
Set sh = ThisWorkbook.Worksheets("HP Service Manager")
sh.AutoFilterMode = False
With sh
On Error Resume Next
.ShowAllData
.Range("E1:N1").AutoFilter 1, "IM*"
AutoFilter = False
End With
End Sub
#
Expect to not have column headers deleted.
The issue is in the second code you shared.
The code is first setting the range here:
Set Rng = Range("E1", Cells(iRow, "E"))
And then here it is trying to delete all visible cells in the range (after applying the filter)
Rng.SpecialCells(xlCellTypeVisible).EntireRow.Delete
which also includes your header cell.
So, a simple way to deal with it could be to set another range like this
Set Rng2 = Range("E2", Cells(iRow, "E"))
and then using it to delete the data
Rng2.SpecialCells(xlCellTypeVisible).EntireRow.Delete
Here is the re-written function for your reference. This only deletes the rows starting from row 2 that are blank. You may want to add some error handing in case there are no blank rows to delete etc.
Sub DeleteRowsAll()
Dim iRow As Long
Dim Rng As Range
Application.ScreenUpdating = False
Rows(1).Insert
Range("E1").Value = "rabbitohs"
With ActiveSheet
.UsedRange
iRow = .Cells.SpecialCells(xlCellTypeLastCell).Row
Set Rng = Range("E1", Cells(iRow, "E"))
Rng.AutoFilter Field:=1, Criteria1:=""
Set Rng2 = Range("E2", Cells(iRow, "E"))
Rng2.SpecialCells(xlCellTypeVisible).EntireRow.Delete
.UsedRange
End With
End Sub
Sub DeleteRowsAll()
Dim LastRow As Long
Dim CellValue As String
LastRow = Worksheets("HP Service Manager").Cells(Rows.Count, "E").End(xlUp).Row
For i = LastRow To 2 Step -1
CellValue = Worksheets("HP Service Manager").Cells(i, "E").Value
If CellValue = "" Then
Worksheets("HP Service Manager").Rows(i).Delete
End If
Next i
End Sub

How can I have my loop search for a value rather than a string of words?

I have some data that has both words and values in cells and I am trying to delete the rows that don’t have values in the cells. My code works now if all of the numbers are negative but if there are positive numbers then my code won’t work. How do I fix this?
Sub tval
Dim s As Long
Dim LastRow As Long
S=2
LastRow= cells.find(“*”,[A1],,, xlByRows,xlPreviousRow).row
Do until s>LastRow
DoEvents
If InStr(1,Cells(s,4), “-“) > 0 Then
S=s+1
Else
Cells(s,4).EntireRow.Delete
LastRow=LastRow -1
End if
Loop
End sub
When deleting rows, you should always start from the end.
Sub tval
Dim s As Long
Dim LastRow As Long
LastRow= Cells(Rows.Count, 1).End(xlUp).Row
For s= LastRow to 2 Step -1
If Not IsNumeric(Cells(s,4)) then
Cells(s,4).EntireRow.Delete
End if
Next s
End sub
This should work for you:
Sub tgr()
Dim ws As Worksheet
Dim rTextConstants As Range
Dim rTextFormulas As Range
Dim rCombined As Range
Set ws = ActiveWorkbook.ActiveSheet
'Exclude row 1 so that only text values found in rows 2+ are found
With ws.Range("A2", ws.Cells(ws.Rows.Count, ws.Columns.Count))
On Error Resume Next 'prevent error if no cells found
Set rTextConstants = .SpecialCells(xlCellTypeConstants, xlTextValues)
Set rTextFormulas = .SpecialCells(xlCellTypeFormulas, xlTextValues)
On Error GoTo 0 'remove on error resume next condition
End With
If Not rTextConstants Is Nothing Then Set rCombined = rTextConstants
If Not rTextFormulas Is Nothing Then
If rCombined Is Nothing Then Set rCombined = rTextFormulas Else Set rCombined = Union(rCombined, rTextFormulas)
End If
If Not rCombined Is Nothing Then
rCombined.EntireRow.Delete
Else
MsgBox "No cells containing text found in sheet '" & ws.Name & "'", , "Error"
End If
End Sub
May I suggest a bit of a different approach:
Before:
Code:
Dim RNG1 As Range, RNG2 As Range
Option Explicit
Sub TestCase()
With ActiveWorkbook.Sheets(1)
Set RNG1 = .Range("A1:A" & .Cells(Rows.Count, 1).End(xlUp).Row)
If RNG1.SpecialCells(xlCellTypeConstants, 1).Count <> RNG1.Cells.Count Then
Set RNG2 = Application.Intersect(RNG1, RNG1.SpecialCells(xlCellTypeConstants, 2))
RNG2.EntireRow.Delete
End If
End With
End Sub
After:
You'll need to change this around to suit your range obviously. It should be a good starting point nonetheless.
You can also use AutoFilter to filter the numbers, and delete the visible cells to accomplish this task. The code accounts for a header row.
With ThisWorkbook.Sheets("Sheet1")
With .Range("A1").CurrentRegion
.AutoFilter
.AutoFilter Field:=4, Criteria1:="<>*"
.Offset(1, 0).SpecialCells(xlCellTypeVisible).EntireRow.Delete
.AutoFilter
End With
End With

Hiding row if cell equals next visible cell

I am trying to write a macro that hides the row if the cell value equals the next visible cell in that column and loops through the whole column. I have read that SpecialCells(xlCellTypeVisible) only works up to 8192 cells and my spreadsheet has 15,000 rows.
I have tried something like this but want to restrict it to only visible cells
Sub Test()
For i = 7 To 15258
If Range("P" & i).Value = Range("P" & i + 1).Value Then
Rows(i).Hidden = True
End If
Next i
End Sub
I have tried to search for a solution but haven't been able to find one yet.
Thanks!
I'd be surprised if this couldn't be optimized just a little bit, but it will work for what you are needing.
You can follow the comments within the code itself to kind of get a sense of what it's doing, but in a nutshell, you are using a For...Next statement to loop through your visible cells. For each visible cell, you will search for the next visible cell and then check to see if that matches. If it does, you add that cell to a special range that tracks all the rows to hide at the end of the code, then hide it.
Sub Test()
Dim ws As Worksheet, lookupRng As Range, rng As Range, lstRow As Long
Set ws = ThisWorkbook.Worksheets(1)
lstRow = 15258
Set lookupRng = ws.Range("P7:P" & lstRow)
Dim rngToHide As Range, i As Long
For Each rng In lookupRng.SpecialCells(xlCellTypeVisible)
Application.StatusBar = "Checking row " & rng.Row & " for matches."
For i = rng.Row + 1 To lstRow 'Loop through rows after rng
If Not ws.Rows(i).Hidden Then 'Check if row is hidden
If rng.Value = ws.Cells(i, "P") Then 'check if the non-hidden row matches
If rngToHide Is Nothing Then 'Add to special range to hide cells
Set rngToHide = ws.Cells(i, "P")
Else
Set rngToHide = Union(rngToHide, ws.Cells(i, "P"))
End If
End If
Exit For 'Exit the second For statement
End If
Next i
Next rng
Application.StatusBar = "Hiding duplicate rows"
If Not rngToHide Is Nothing Then rngToHide.EntireRow.Hidden = True
Application.StatusBar = False
End Sub

Excel expression to copy rows but remove blank rows

I need to copy data from one worksheet into another. However, I need a conditional copy operation that will skip rows based on criteria.
For example, if I start with...
Active Value
yes 1
no 2
no 3
yes 4
no 5
no 6
I only want to copy rows that are Active=yes, so I would end up with...
Value
1
4
Can someone show me how this is done with 1) a macro and 2) a formula?
Formula approach:
suppose your data are in sheet1, range A2:B7.
Then use this formula in sheet2 cell A2:
=IFERROR(INDEX(Sheet1!B:B,SMALL(IF(Sheet1!$A$2:$A$7="yes",ROW(Sheet1!$A$2:$A$7)),ROW()-ROW($A$2)+1)),"")
with array entry (CTRL+SHIFT+ENTER) and then drag it down.
VBA approach:
You can use AutoFilter:
Sub test()
Dim ws1 As Worksheet, ws2 As Worksheet
Dim rng As Range, rngToCopy As Range
Dim lastrow As Long
'change Sheet1 and Sheet2 to suit
Set ws1 = ThisWorkbook.Worksheets("Sheet1")
Set ws2 = ThisWorkbook.Worksheets("Sheet2")
With ws1
'assumung that your data stored in column A:B, Sheet1
lastrow = .Cells(.Rows.Count, "A").End(xlUp).Row
Set rng = .Range("A1:B" & lastrow)
'clear all filters
.AutoFilterMode = False
With rng
'apply filter
.AutoFilter Field:=1, Criteria1:="yes"
On Error Resume Next
'get only visible rows
Set rngToCopy = .SpecialCells(xlCellTypeVisible)
On Error GoTo 0
End With
'copy range
If Not rngToCopy Is Nothing Then rngToCopy.Copy Destination:=ws2.Range("A1")
'clear all filters
.AutoFilterMode = False
End With
Application.CutCopyMode = False
End Sub
Note, if you want to copy only Value column, change
Set rngToCopy = .SpecialCells(xlCellTypeVisible)
to
Set rngToCopy = .Offset(, 1).Resize(, .Columns.Count - 1).SpecialCells(xlCellTypeVisible)
It's easy enough with a macro. Assuming you're copying from the first sheet to the second sheet, and that your sample above is in columns A and B, you could do the following:
Public Sub ConditionalCopy()
Dim copyRng As Range
Set copyRng = Worksheets(1).Range("B2:B7")
Dim pasteRng As Range
Set pasteRng = Worksheets(2).Range("A2")
Dim i As Long
i = 0
For Each cell in copyRng.Cells
If cell.Offset(0, -1).Value2 = "yes" Then
pasteRng.Offset(i,0).Value2 = cell.Value2
i = i + 1
End If
Next cell
End Sub
Doing it with a formula presents a challenge in terms of not leaving any blank rows on the second sheet. It would be pretty trivial to just use the following in the second sheet:
=If(A2 = "yes",b2,"")
And copy that down, but you're going to end up with blank rows that you'll have to go back and delete yourself. If you have the ability to use the macro, it's straightforward enough that I would go that route rather than sinking too much effort into devising a formula. The more I think about it, the more I feel like it has to be a programmatic solution to avoid double references.
If you use seperate counters for the source and destination rows, and use cell references rather than ranges the following routine should do the trick
Public Sub copyactivevalue()
Dim i As Integer
Dim j As Integer
Dim acts As Excel.Worksheet
Dim news As Excel.Worksheet
Set acts = Excel.Worksheets("sheet1")
Set news = Excel.Worksheets("sheet2")
With acts
j = 2
For i = 2 To 7
If acts.Cells(i, 1).Value = "yes" Then
news.Cells(j, 1) = acts.Cells(i, 2).Value
j = j + 1
End If
Next
End With
Set acts = Nothing
Set news = Nothing
End Sub
Hope this helps

Excel VBA, How to select rows based on data in a column?

Sub SelectAllReleventText()
Do While Range(“A1”).Offset(1, 6) <> Empty
Rows(ActiveCell.Row).Select
ActiveCell.Offset(1, 0).Select
Loop
End Sub
Here is my script, I've been told it doesn't do what it is meant to, which I expected since this was my first attempt. I am coming up with a variable not defined error. I thought I defined the variable, but I guess it wasn't specific enough for Excel VBA.
This is what I am attempting to do.
In Workbook 1, On B6 there is an alphanumeric name, I want that row to be selected.
Go down one row, if there is text there select that row.
Continue till text is no longer prevalent.
Copy selected rows.
Paste into another workbook (Workbook2), into tab 1, starting on row 2, since row 1 has headers.
Thanks in advance. Just a heads up, I am using the Options Explicit in my VBA because I was told it was the "right way to do thing"...
Yes using Option Explicit is a good habit. Using .Select however is not :) it reduces the speed of the code. Also fully justify sheet names else the code will always run for the Activesheet which might not be what you actually wanted.
Is this what you are trying?
Option Explicit
Sub Sample()
Dim lastRow As Long, i As Long
Dim CopyRange As Range
'~~> Change Sheet1 to relevant sheet name
With Sheets("Sheet1")
lastRow = .Range("A" & .Rows.Count).End(xlUp).Row
For i = 2 To lastRow
If Len(Trim(.Range("A" & i).Value)) <> 0 Then
If CopyRange Is Nothing Then
Set CopyRange = .Rows(i)
Else
Set CopyRange = Union(CopyRange, .Rows(i))
End If
Else
Exit For
End If
Next
If Not CopyRange Is Nothing Then
'~~> Change Sheet2 to relevant sheet name
CopyRange.Copy Sheets("Sheet2").Rows(1)
End If
End With
End Sub
NOTE
If if you have data from Row 2 till Row 10 and row 11 is blank and then you have data again from Row 12 then the above code will only copy data from Row 2 till Row 10
If you want to copy all rows which have data then use this code.
Option Explicit
Sub Sample()
Dim lastRow As Long, i As Long
Dim CopyRange As Range
'~~> Change Sheet1 to relevant sheet name
With Sheets("Sheet1")
lastRow = .Range("A" & .Rows.Count).End(xlUp).Row
For i = 2 To lastRow
If Len(Trim(.Range("A" & i).Value)) <> 0 Then
If CopyRange Is Nothing Then
Set CopyRange = .Rows(i)
Else
Set CopyRange = Union(CopyRange, .Rows(i))
End If
End If
Next
If Not CopyRange Is Nothing Then
'~~> Change Sheet2 to relevant sheet name
CopyRange.Copy Sheets("Sheet2").Rows(1)
End If
End With
End Sub
Hope this is what you wanted?

The easiest way to do it is to use the End method, which is gives you the cell that you reach by pressing the end key and then a direction when you're on a cell (in this case B6). This won't give you what you expect if B6 or B7 is empty, though.
Dim start_cell As Range
Set start_cell = Range("[Workbook1.xlsx]Sheet1!B6")
Range(start_cell, start_cell.End(xlDown)).Copy Range("[Workbook2.xlsx]Sheet1!A2")
If you can't use End, then you would have to use a loop.
Dim start_cell As Range, end_cell As Range
Set start_cell = Range("[Workbook1.xlsx]Sheet1!B6")
Set end_cell = start_cell
Do Until IsEmpty(end_cell.Offset(1, 0))
Set end_cell = end_cell.Offset(1, 0)
Loop
Range(start_cell, end_cell).Copy Range("[Workbook2.xlsx]Sheet1!A2")
