Hello,

Thanks for reading.

I have columns of data from column C right through to column WZZ. What I want to do is to put all of this data into column A only. Each column has the exact same amount of rows - data starts at row 6 and finishes at to 2,500.

Is there a qucik way to do this?


Kind Regards
 
Oops. Try again:

Code:
Sub combineCols()
    Dim r As Range
    Dim a(), b()
    Dim lastRow As Long, totalValues As Long, i As Long, j As Long, k As Long
    
    lastRow = Cells.SpecialCells(xlCellTypeLastCell).Row
    Set r = Range("A6", Cells(lastRow, "WZ"))
    totalValues = Application.CountA(r)
    If totalValues > Rows.Count Then
        MsgBox "Can't be done. Not enough rows!!!", vbCritical
    Else
        k = 0
        ReDim b(1 To totalValues, 1 To 1)
        For j = 1 To UBound(a, 2)
            For i = 1 To UBound(a)
                If LenB(a(i, j)) Then
                    k = k + 1
                    b(k, 1) = a(i, j)
                End If
            Next j
        Next j
        Workbooks.Add.Sheets(1).Range("A1").Resize(totalValues).Value = b
        Erase a
        Erase b
    End If
    Set r = Nothing
End Sub

Excel Facts

Pivot Table Drill Down
Double-click any number in a pivot table to create a new report showing all detail rows that make up that number
with optional csv export if there are just too many values:

Code:
Sub combineCols()
    Dim r As Range
    Dim a(), b()
    Dim lastRow As Long, totalValues As Long, i As Long, j As Long, k As Long
    
    lastRow = Cells.SpecialCells(xlCellTypeLastCell).Row
    Set r = Range("A6", Cells(lastRow, "WZ"))
    totalValues = Application.CountA(r)
    k = 0
    If totalValues > Rows.Count Then
        MsgBox "Can't be done. Not enough rows!!!", vbCritical
        If MsgBox("Would you like to export to a csv?", vbYesNo + vbInformation) = vbYes Then
            Open "c:\export.csv" For Output As [URL=https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=1]#1[/URL]  '<-- Change c:\export.csv to whatever you would like.
            For j = 1 To UBound(a, 2)
                For i = 1 To UBound(a)
                    If LenB(a(i, j)) Then
                        k = k + 1
                        Write [URL=https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=1]#1[/URL] , IIf(k > 1, vbCrLf, "") & a(i, j)
                    End If

            Next j
            Close [URL=https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=1]#1[/URL] 
        End If
    Else
        ReDim b(1 To totalValues, 1 To 1)
        For j = 1 To UBound(a, 2)
            For i = 1 To UBound(a)

Thanks for your expertise on this.

I tried the code but received a message stating 'Complie Error: Invalid Next control variable reference' and it is indicating this on the first 'Next j' line of code. I cannot fix this as my code knowledge is zero

sorry. I'm out atm so I've just been trying to type code straight into the browser on my phone.

Thanks again, working on your coding whilst out and about on your phone is highly impressive. Still, I have copied what you did and still no luck - is it easy to whack it into an excel file and to send over so that I can see it in action? More likely user error my end.

Not sure what I did wrong but yes your code works perfectly now - works as intended and is highly impressive. Big thank you all round, very impressive skills set

How easy is it to modify the code so that once it looks at the first tab and brings in the data into more column, it then looks at the next tab and does the same process, and then the next tab, etc?

That would be pretty straightforward. You could use this:

Code:
Sub combineCols()
    Dim r As Range
    Dim a(), b()
    Dim lastRow As Long, totalValues As Long, i As Long, j As Long, k As Long
    Dim allowCSVExport As Boolean
    Dim outputWb As Workbook, outputSht As Worksheet, sht As Worksheet


    allowCSVExport = False '<-- Change to True if you want the export to csv option
    
    For Each sht In ActiveWorkbook.Sheets
        lastRow = sht.Cells.SpecialCells(xlCellTypeLastCell).Row
        Set r = sht.Range("A6", sht.Cells(lastRow, "WZ"))
        totalValues = Application.CountA(r)
        k = 0
        a = r.Value
        If outputWb Is Nothing Then
            Set outputWb = Workbooks.Add
            Set outputSht = outputWb.Sheets(1)
        Else
            Set outputSht = outputWb.Sheets.Add(After:=outputWb.Sheets(outputWb.Sheets.Count))
        End If
        If totalValues > outputSht.Rows.Count Then
            MsgBox "Can't be done. Not enough rows!!!", vbCritical
            If allowCSVExport Then
                If MsgBox("Would you like to export to a csv?", vbYesNo + vbInformation) = vbYes Then
                    Open "c:\export.csv" For Output As [URL=https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=1]#1[/URL]    '<-- Change c:\export.csv to whatever you would like.
                    For j = 1 To UBound(a, 2)
                        For i = 1 To UBound(a)
                            If LenB(a(i, j)) Then
                                k = k + 1
                                Write [URL=https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=1]#1[/URL] , IIf(k > 1, vbCrLf, "") & a(i, j)
                            End If
                        Next i
                    Next j
                    Close [URL=https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=1]#1[/URL] 
                End If
            End If
        Else
            ReDim b(1 To totalValues, 1 To 1)
            For j = 1 To UBound(a, 2)
                For i = 1 To UBound(a)
                    If LenB(a(i, j)) Then
                        k = k + 1
                        b(k, 1) = a(i, j)
                    End If
                Next i
            Next j
            outputSht.Range("A1").Resize(totalValues).Value = b
            Erase b
        End If
        Erase a
        Set r = Nothing
    Next sht
End Sub

However, because I like to try and make my code more than just single use, personally I'd probably do something like this:

Code:
Option Explicit


Sub combineAllSheets()
    Dim sht As Worksheet, outputSht As Worksheet
    Dim outputWb As Workbook, sourceWb As Workbook
    Dim i As Long
    Dim appendSheets As Boolean, success As Boolean
    
    appendSheets = False '<-- Set to True if you want to add the sheets to the source workbook rather than create a new one.
    
    Application.ScreenUpdating = False
    On Error GoTo clean_exit
    'If you want to always reference this workbook as opposed to the currently active
    'workbook then change the line below to: Set sourceWb = ThisWorkbook
    Set sourceWb = ActiveWorkbook
    If appendSheets Then
        Set outputWb = sourceWb
        i = outputWb.Sheets.Count
    Else
        Set outputWb = Workbooks.Add
        i = 0
    End If
    For Each sht In sourceWb.Sheets
        i = i + 1
        While outputWb.Sheets.Count < i
            outputWb.Sheets.Add After:=outputWb.Sheets(outputWb.Sheets.Count)
        Wend
        Set outputSht = outputWb.Sheets(i)
        success = combineSheetCols( _
            source:=sht, _
            dataStart:="A6", _
            colLimit:="WZ", _
            dest:=outputSht, _
            skipBlanks:=True, _
            csvFallback:=True)
        If Not success Then
            Application.DisplayAlerts = False
            If outputWb.Sheets.Count > 1 Then outputSht.Delete
            Application.DisplayAlerts = True
            i = i - 1
        End If
    Next sht
    outputWb.Activate
    
clean_exit:
    Set sht = Nothing
    Set sourceWb = Nothing
    Set outputSht = Nothing
    Set outputWb = Nothing
    Application.ScreenUpdating = True
    If Err.Number Then Err.Raise (Err)
End Sub


'Combines the values on the supplied sheet <source> into a single column.
'Returns True if the operation was successful; False otherwise (logs failure to Immediate window).
'Optional Parameters:
'   dataStart:   A string value representing the first cell where data is found (eg. "A2").
'                If omitted the function defaults to "A1".
'
'   colLimit:    A string value representing the last column in which data is found (eg. "Z").
'                If omitted the function defaults to the last used column.
'
'   dest:        A Worksheet object to be used as the output for the combined values.
'                If omitted then the function will create a new blank workbook to output values.
'
'   skipBlanks:  If set to True then only none blank values are output
'
'   csvFallback: If set to True then if there are too many values to be combined into a single

Absolute genius this code - thank you, I hope your making vast sums in some financial institution with your vb magic!

That would be pretty straightforward. You could use this:

Code:
Sub combineCols()
    Dim r As Range
    Dim a(), b()
    Dim lastRow As Long, totalValues As Long, i As Long, j As Long, k As Long
    Dim allowCSVExport As Boolean
    Dim outputWb As Workbook, outputSht As Worksheet, sht As Worksheet


    allowCSVExport = False '<-- Change to True if you want the export to csv option
    
    For Each sht In ActiveWorkbook.Sheets
        lastRow = sht.Cells.SpecialCells(xlCellTypeLastCell).Row
        Set r = sht.Range("A6", sht.Cells(lastRow, "WZ"))
        totalValues = Application.CountA(r)
        k = 0
        a = r.Value
        If outputWb Is Nothing Then
            Set outputWb = Workbooks.Add
            Set outputSht = outputWb.Sheets(1)
        Else
            Set outputSht = outputWb.Sheets.Add(After:=outputWb.Sheets(outputWb.Sheets.Count))
        End If
        If totalValues > outputSht.Rows.Count Then
            MsgBox "Can't be done. Not enough rows!!!", vbCritical
            If allowCSVExport Then
                If MsgBox("Would you like to export to a csv?", vbYesNo + vbInformation) = vbYes Then
                    Open "c:\export.csv" For Output As [URL="https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=1"]#1[/URL]    '<-- Change c:\export.csv to whatever you would like.
                    For j = 1 To UBound(a, 2)
                        For i = 1 To UBound(a)
                            If LenB(a(i, j)) Then
                                k = k + 1
                                Write [URL="https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=1"]#1[/URL] , IIf(k > 1, vbCrLf, "") & a(i, j)
                            End If
                        Next i
                    Next j
                    Close [URL="https://www.mrexcel.com/forum/usertag.php?do=list&action=hash&hash=1"]#1[/URL] 
                End If
            End If
        Else
            ReDim b(1 To totalValues, 1 To 1)
            For j = 1 To UBound(a, 2)
                For i = 1 To UBound(a)
                    If LenB(a(i, j)) Then
                        k = k + 1
                        b(k, 1) = a(i, j)
                    End If
                Next i
            Next j
            outputSht.Range("A1").Resize(totalValues).Value = b
            Erase b
        End If
        Erase a
        Set r = Nothing
    Next sht
End Sub

However, because I like to try and make my code more than just single use, personally I'd probably do something like this:

    Application.ScreenUpdating = False
    On Error GoTo clean_exit
    'If you want to always reference this workbook as opposed to the currently active
    'workbook then change the line below to: Set sourceWb = ThisWorkbook
    Set sourceWb = ActiveWorkbook
    If appendSheets Then
        Set outputWb = sourceWb
        i = outputWb.Sheets.Count
    Else
        Set outputWb = Workbooks.Add
        i = 0
    End If
    For Each sht In sourceWb.Sheets
        i = i + 1
        While outputWb.Sheets.Count < i
            outputWb.Sheets.Add After:=outputWb.Sheets(outputWb.Sheets.Count)
        Wend
        Set outputSht = outputWb.Sheets(i)
        success = combineSheetCols( _

            i = i - 1

No problem at all.

Hopefully you will see that:
typeOfArray can all be used in any project with no dependencies.
flattenArray and outputArrayAsCSV can be used so long as they are in a project which includes typeOfArray
combineSheetCols will also need you to include the above 3 functions as it makes use of each of these.

combineAllSheets as actually pretty simple all told which simply leverages the helper functions to perform it's task and should probably be considered as standalone sub-routine specific to this project only (it could, however, be adapted quite easily).
