Select and extract row of data to another sheet - vba

I'm working with big worksheet containing stocks information, with columns organized like this :
ID DATE TIME PRICE QUANTITY NBE
It goes on for 500k+ rows, and I have 10+ sheets to go through. I need to extract only the first two trade of each trading day, and create a new list on a new sheet (Sheet1). The first trade of every day is always at "09:00:00".
So far I wrote this piece of code, in which I tried to copy the two lines I need and then paste them into Sheet1 thus creating the new list. It runs without errors, but nothing shows up...
Sub Macro1()
i = 2
Range("C2").Select
Range(Selection, Selection.End(xlDown)).Select
For Each Cell In Selection
If Day(.Range("B" & cRow).Value) <> Day(.Range("B" & cRow - 1).Value) Then
ActiveCell.EntireRow.Copy
ActiveWorkbook.Sheets("Sheet1").Rows(i).Paste
ActiveCell.Offset(1).Copy
ActiveWorkbook.Sheets("Sheet1").Rows(i + 1).Paste
i = i + 2
End If
Next Cell
End Sub
Shouldn't i select and the copy paste the two rows together? Or is it possible to create a range consisting of 2 rows and 6 columns from the activecell and then copy paste that range?
EDIT 1: It's not working.. I updated it like above, but I still get an error 438 here ActiveWorkbook.Sheets("Sheet1").Rows(i).Paste
EDIT 2: I'm def a big noob. Just realized not every first trade was made at 9:00:00 so i need to select the row based on wether or not one day have passed, and select the first two.
Can I use this condition instead : If Day(Range("B" & cRow).Value) <> Day(Range("B" & cRow - 1).Value) Then ?

I'm betting that your Time column is formatted as a Date/Time field, so you're comparing a string 09:00:00 to a long (date/time) and it's never going to be equal.
Try this:
if Format(Cell.Value, "hh:mm:ss") = "09:00:00" Then
And your English isn't bad at all...

This should do it quickly
make sure your on the sheet with data and run it, and it will copy it onto sheet1 in the same workbook starting at row2
you should make sure sheet1 is empty also , with .clearContents
Sub Macro1()
Dim lngFirstRow As Long
Dim lngLastRow As Long
Dim cRow As Long
Dim shSrc As Worksheet
Dim lngNextDestRow As Long
Dim shDest As Worksheet
Application.ScreenUpdating = False
Set shSrc = ActiveWorkbook.ActiveSheet
Set shDest = ActiveWorkbook.Sheets("Sheet1")
With shSrc
lngFirstRow = 2
lngLastRow = .Cells.Find(What:="*", After:=.Cells.Cells(1), LookAt:=xlPart, LookIn:=xlFormulas, SearchOrder:=xlByRows, SearchDirection:=xlPrevious, MatchCase:=False).Row
lngNextDestRow = 2
For cRow = lngFirstRow To lngLastRow Step 1
If Format(.Range("C" & cRow).value, "hh:mm:ss") = "09:00:00" Then
.Rows(cRow).EntireRow.Copy Destination:=shDest.Range("A" & lngNextDestRow )
.Rows(cRow+1).EntireRow.Copy Destination:=shDest.Range("A" & lngNextDestRow+1 )
lngNextDestRow = lngNextDestRow + 2
End If
Next cRow
End With
Application.ScreenUpdating = True
End Sub

When you refrence a sheet using the following line
ActiveWorkbook.Sheets(Sheet1).Rows(i).Paste
Sheet1 is likely a variable that is not defined properly. If "Sheet1" is the actual name of the sheet then enclose it in doublequotes
ActiveWorkbook.Sheets("Sheet1").Rows(i).Paste
After looking at #FreeMan's answer....you should do that first. You'll probably get an error 9 subscript error after you fix what he said to do.

Creating a macro that properly filters data and puts it on another sheet

I have a large dataset that is ordered in a weird way, as in the picture:
This is how my data looks currently
This is what i want it to be like
So mainly I want to do 2 things, first i want to cut the two other columns that display data, and paste them underneath the first column, but only for the first weeks period, and then sort the data, macro recording doesn't work very well since weeks are really months, therefore the amount of days changes per month, hence the height of each column.
My idea is to use a while loop to scroll through the first column (the first one displaying "Day", for each non-number entry (say the first no-greater than zero input), and then cut the whole three block array and paste it somewhere else, say a new sheet called Week "n", given it's the n'th week.
Then properly order this array, copying the two right blocks underneath the first one, and sort them by day and hour.
This I want to do for each data period of a week, but I'm not that well versed on vba's syntax to achieve this, mostly i do not know how to order the array the way im looking to once they are copied to new sheets, neither do i know how to do it if i were not to add new sheets and instead reformat it in place.
Any help is welcome.
Considering your data is set up as per the following image...
Place the following code on a Standard Module like Module1...
Sub TransformWeekData()
Dim sws As Worksheet, dws As Worksheet
Dim lr As Long, dlr As Long, i As Long
Dim Rng As Range
Application.ScreenUpdating = False
Set sws = Sheets("Sheet1") 'Source data sheet
lr = sws.Cells(Rows.Count, 1).End(xlUp).Row
On Error Resume Next
Set dws = Sheets("Combined Data") 'Output Sheet
dws.Cells.Clear
On Error GoTo 0
If dws Is Nothing Then
Set dws = Sheets.Add(after:=sws)
dws.Name = "Combined Data"
End If
On Error Resume Next
For Each Rng In sws.Range("A2:A" & lr).SpecialCells(xlCellTypeConstants, 1).Areas
If dws.Range("A1").Value = "" Then
dlr = 1
Else
dlr = dws.Range("A" & Rows.Count).End(3)(2).Row
End If
dws.Range("A" & dlr).Value = Rng.Cells(1).Offset(-2, 0).Value
dws.Range("A" & dlr + 1 & ":C" & dlr + 1).Value = Array("Day", "Amount", "Hour")
For i = 1 To 9 Step 3
dlr = dws.Range("A" & Rows.Count).End(3)(2).Row
Rng.Offset(, i - 1).Resize(Rng.Cells.Count, 3).Copy dws.Range("A" & dlr)
Next i
Next Rng
dlr = dws.Range("A" & Rows.Count).End(xlUp).Row
For Each Rng In dws.Range("A2:A" & dlr).SpecialCells(xlCellTypeConstants, 1).Areas
Rng.Resize(Rng.Cells.Count, 3).Sort key1:=Rng.Cells(1), order1:=xlAscending, key2:=Rng.Cells(1, 3), order2:=xlAscending, Header:=xlNo
Next Rng
Application.ScreenUpdating = True
End Sub
The code above will insert a sheet called Combined Data if doesn't exist in the workbook with the data in the desired format as shown in the image below...
You may change the output sheet's name as per your requirement.

First blank ("") cell in column with IF formula

I have a macro that exactly copies one sheet's data into another.
Sub QuickViewRegMgmt()
("Reg Management").Select
Cells.Select
Selection.Copy
Sheets("Quick View Reg Mgmt").Select
Cells.Select
ActiveSheet.Paste
End Sub
I would like for this macro to also go to the last non-blank cell in Column C (or first blank, I really don't care either way). I tried simple end/offset code, e.g.
Range("A1").End(xldown).Offset(1,0).Select
My problem, however, is that the direct copy macro also copies the underlying formulas, which for Column C is an IF formula. Therefore, no cell in the column is actually empty, but rather they all have an IF formula resulting in a true/false value (respectively, a "" or VLOOKUP).
=IF(VLOOKUP('Reg Management'!$Y260,'Reg Guidance'!$A:$V,3,FALSE)=0,"",VLOOKUP('Reg Management'!$Y260,'Reg Guidance'!$A:$V,3,FALSE))
That means the end/offset code goes to the last cell in the column with the formula (C1000) instead of going to the first cell that has a value of "" (which is currently C260).
What code can I add to this macro to select the first cell that contains an IF formula resulting in a value of "" ---- which has the appearance of being blank?
After trying to be fancy with SpecialCells(), or using Find() or something I couldn't get it ...so here's a rather "dirty" way to do it:
Sub test()
Dim lastRow As Long, lastFormulaRow As Long
lastRow = Range("A" & Rows.Count).End(xlUp).Row
Dim i As Long
For i = lastRow To 1 Step -1
If Cells(i, 1).Formula <> "" And Cells(i, 1).Value = "" Then
lastFormulaRow = i
Exit For
End If
Next i
End Sub
Edit2: Here's one using .SpecialCells(). Granted I think we can whittle this down more, I like it better:
Sub lastRow()
Dim tempLastRow As Long
tempLastRow = Range("C" & Rows.Count).End(xlUp).Row
Dim lastRow As Range
Set lastRow = Columns(3).SpecialCells(xlCellTypeFormulas).Find(What:="", LookIn:=xlValues, LookAt:=xlWhole, searchdirection:=xlPrevious, after:=Range("C" & tempLastRow))
Debug.Print lastRow.Row
End Sub
It returns 10 as the row.
Edit: Be sure to add the sheet references before Range() and Cells() to get the last row. Otherwise, it's going to look at your active sheet to get the info.

Excel 2010 VBA - How to optimize this code so it doesn't lag out?

I'm new to VBA and I have recently been creating a few macros. I currently have one that works, but it isn't very cooperative at times. I've done a bunch of reading on how to optimize VBA code, but I'm still not getting very far. I understand using Select is bad, and I've removed as much of the Select lines as I could on my own. I've also read that many if statements combined with loops can be hard to run as well (of course I have multiples of both).
So I know some of the reasons why my code is bad, but I don't really know how to fix it. I added
Application.ScreenUpdating = False
Application.ScreenUpdating = True
to my macro as well. This has helped, but not much. I have other macros that can run for a long time and never freeze up. This macro freezes if it doesn't finish in 10-15 seconds. If I only have a couple 100 rows of data it runs no problem. If I have a few 1000 lines of data it doesn't finish before it freezes.
Option Explicit
Sub FillGainerPrices()
Application.ScreenUpdating = False
'Search each name on "Gainer Prices" and if the same name is on "Gainers", but not on Gainer Prices _
move it over to Gainer Prices tab. Then call Historical Query and Fill Names
Dim LastRow1 As Long
LastRow1 = Sheets("Gainers").Cells.Find("*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious).Row
Dim LastRow2 As Long
LastRow2 = Sheets("Gainer Prices").Cells.Find("*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious).Row
Dim Name1 As Range
Dim Name2 As Range
For Each Name1 In Sheets("Gainers").Range("B2:B" & LastRow1)
Set Name2 = Sheets("Gainer Prices").Range("A2:A" & LastRow2).Find(Name1, LookIn:=xlValues, LookAt:=xlWhole)
If Name2 Is Nothing Then
If Name1.Offset(0, -1) < Date - 15 Then
Name1.Copy
Sheets("Gainer Prices").Select
Range("C" & Cells.Rows.Count).End(xlUp).Offset(1, -2).Select
ActiveSheet.Paste
Call HistoricalQuery
End If
End If
Next Name1
Application.ScreenUpdating = True
'Fill in Names and remaining symbols here
Call FillNamesAndSymbols
End Sub
Call HistoricalQuery and Call FillNamesAndSybmols are pretty quick and do not seem to have any issues when I run them by themselves so I don't think they are causing the problem. I'm guessing the issue is searching for one Name 1000's of times and then copying and pasting over and over, but I can't figure out how to get rid of the copy and paste part without the macro giving me wrong results.
The end goal of the macro is to go to the 2nd sheet and see if those names are on the first sheet. If not, it moves the names over, and then for each name it moves over it calls another macro to pull historical data for that name. Finally at the end it just does some formatting and filling in or deleting of blank cells. If anyone can direct me in the correct direction I would appreciate it. Thanks!
Try this code.
Improvments:
Timing: my code: 0.8828125 sec, your code: 10.003 sec. (tested with 1000 rows in both sheets)
I'm using array to store values from second sheet: arr = Sheets("Gainer Prices").Range("A2:A" & LastRow2).Value - much faster for huge data
I'm using Application.Match instead Range.Find - it's faster as well.
I'm using Range(..).Value = Range(..).Value instead copy/paste
avoid using select/active statement
Sub FillGainerPrices()
Dim LastRow1 As Long
Dim LastRow2 As Long
Dim Lastrow3 As Long
Dim Name1 As Range
Dim sh1 As Worksheet
Dim sh2 As Worksheet
Dim arr As Variant
'remember start time
Dim start as Long
start = Timer
Application.ScreenUpdating = False
Set sh1 = ThisWorkbook.Sheets("Gainers")
Set sh2 = ThisWorkbook.Sheets("Gainer Prices")
With sh1
LastRow1 = .Cells(.Rows.Count, "B").End(xlUp).Row
End With
With sh2
LastRow2 = .Cells(.Rows.Count, "A").End(xlUp).Row
arr = .Range("A2:A" & LastRow2).Value
End With
For Each Name1 In sh1.Range("B2:B" & LastRow1)
If IsError(Application.Match(Name1.Value, arr, 0)) Then
If Name1.Offset(0, -1) < Date - 15 Then
With sh2
Lastrow3 = .Cells(.Rows.Count, "C").End(xlUp).Row
.Range("A" & Lastrow3 + 1).Value = Name1.Value
End With
Call HistoricalQuery
End If
End If
Next Name1
'Fill in Names and remaining symbols here
Call FillNamesAndSymbols
Application.ScreenUpdating = True
'To see timing result press CTRL+G in the VBE window, or change Debug.Print to MsgBox
Debug.Print "Code evaluates for: " & Timer - start
End Sub
instead of
Name1.Copy
Sheets("Gainer Prices").Select
Range("C" & Cells.Rows.Count).End(xlUp).Offset(1, -2).Select
ActiveSheet.Paste
you might try something like this:
Name1.copy destination:=Sheets("Gainer Prices").Range("C" & Cells.Rows.Count).End(xlUp).Offset(1, -2)
or perhaps
Sheets("Gainer Prices").Range("C" & Cells.Rows.Count).End(xlUp).Offset(1, -2).value=Name1.value

Copy multiple rows from one worksheet to another worksheet using macro/vba

I've looked around the forum and played with various options but not found a clear match for my problem:
My task is to copy data from a worksheet (called “workorders”) to a second worksheet (called “Assignments”). The data to be copied is from the “workorders” worksheet starting at cell range “E2, P2:S2”; and also copied from each row (same range) until column “P” is empty – (the number of rows to be copied can vary each time we need to run this macro so we can’t select a standard range) . Then pasted into the “Assignments” worksheet, starting at cell “A4”. I’ve used the forum so far to successfully copy a single row of date (from row 2) – I admit that’s the easy part, and I’ve used various versions of code to achieve this.
I’ve also tried some code (which I found via watching a youtube clip and modifying http://www.youtube.com/watch?v=PyNWL0DXXtQ )to allow me to run a loop which repeats the copy process for each required row in the “workorders” worksheet and then pastes the data into the “assignments” worksheet- but this is where I am not getting it right, I think I’m along the right lines and think I’m not far off but any help would be very useful.
Code examples below (first 2 only copy first row, 3rd example is where I’ve tried to loop and copy multiple rows:
Sub CopyTest1()
' CopyTest1 Macro
'copy data from workorders sheet
'Worksheets("workorders").Range("E2,P2,Q2,R2,S2").Copy
Worksheets("workorders").Range("E2, P2:S2").Copy
'paste data to assignments sheet
'sheets("assigments dc").Range("A4").Paste
Sheets("Assigments DC").Select
Range("A4").Select
ActiveSheet.Paste
Application.CutCopyMode = False
End Sub
Sub CopyTest2()
Sheets("workorders").Range("e2,p2,q2,r2,s2").Copy Sheets("assigments dc").Range("a4")
End Sub
Sub CopyTest3()
Dim xrow As Long
'Dim xrow As String
xrow = 2
Worksheets("workorders").Select
Dim lastrow As Long
lastrow = Cells(Rows.Count, 16).End(xlUp).Row
Do Until xrow = lastrow + 1
ActiveSheet.Cells(xrow, 16).Select
If ActiveCell.Text = Not Null Then
'Range("E2,P2,Q2,R2,S2").Copy
'Selection = Range("E2,P2,Q2,R2,S2").Copy
'Cells(xrow, 5).Copy
Cells(xrow, 5).Copy
Sheets("Assigments DC").Select
Range("A4").Select
ActiveSheet.Paste
Application.CutCopyMode = False
Sheets("workorders").Select
End If
xrow = xrow + 1
Loop
End Sub
Try this:
Sub LoopCopy()
Dim shWO As Worksheet, shAss As Worksheet
Dim WOLastRow As Long, Iter As Long
Dim RngToCopy As Range, RngToPaste As Range
With ThisWorkbook
Set shWO = .Sheets("Workorders") 'Modify as necessary.
Set shAss = .Sheets("Assignments") 'Modify as necessary.
End With
'Get the row index of the last populated row in column P.
'Change accordingly if you want to use another column as basis.
'Two versions of getting the last row are provided.
WOLastRow = shWO.Range("P2").End(xlDown).Row
'WOLastRow = shWO.Range("P" & Rows.Count).End(xlUp).Row
For Iter = 2 to WOLastRow
Set RngToPaste = shAss.Range("A" & (Iter + 2))
With shWO
Set RngToCopy = Union(.Range("E" & Iter), .Range("P" & Iter & ":S" & Iter))
RngToCopy.Copy RngToPaste
End With
Next Iter
End Sub
Read the comments first and test.
Let us know if this helps.
From what I see, you are only copying the cell in Column E. You could correct this by replacing Cells(xrow, 5).Copy with
Union(Sheets("workorders").Cells(xrow,5),Sheets("workorders").Range(Cells(xrow,"P"),Cells(xrow,"S")).Copy
However, using Select and Copy are not ideal. Instead, you can assign the value of the range directly:
Sheets("Assignments DC").Range("A4").Value = Union(Sheets("workorders").Cells(xrow,5),Sheets("workorders").Range(Cells(xrow,"P"),Cells(xrow,"S")).Value
More info on the Union method and why using Select is bad.
Is it even possible to run a line like this?
Worksheets("workorders").Range("E2, P2:S2").Copy
Each time I try different ways to copy/select a range which contains in my case, A3 and the range A34:C40 ("A3, A34:C40").Copy i get an error saying theres to many parameters.. Could this be because I'm running excel 2007?
Any tips or help would be greatly apreciated! :)

Consolitate data from multible sheets ,re-arrange the data as per the column name

i want a macro to consolidate the data form multiple sheets to one sheet.. here i given the example ..
Sheet 1
a1:Name b1:Age

.
sheet 2
a1:Age b1:Name c1:Dept
a2:60 b2:saran c2:Comp sce
a3:31 b3:rajan c3:B.com
the result should be like this
consolidate sheet

Please help me in this ..THanks in advance
First I identify some mistakes and bad practices in your code then I consider how to redesign your macro to achieve your objectives.
Issue 1
The primary purpose of On Error is to allow you to terminate tidily if an unexpected error occurs. You should not use it to avoid errors you expect and you should not ignore errors.
Consider the functions LastRow and LastCol. In both cases, if the Find fails, you ignore the error and carry on. But that means these functions return an incorrect value, so you get another error in the calling routine. If the Find fails you should investigate not ignore. This is true of any other error.
Issue 2
Find returns Nothing if the sheet is empty. You call functions LastRow and LastCol for worksheet "RDBMergeSheet" when it is empty. The code should be:
Set Rng = sh.Cells.Find( ...)
If Rng Is Nothing Then
' Sheet sh is empty
LastRow = 0
Else
LastRow = Rng.Row
End If
Here I have set LastRow to 0 if the worksheet is empty. This ceases to be a side effect of an error but a documented feature of the function: "Return value = 0 means the worksheet is empty." The calling routine must check for this value and skip any empty worksheets. There are other approaches but the key point is: provide code to handle expected or possible errors in a tidy manner. For function LastCol you need LastCol = Rng.Column.
Issue 3
The minimum syntax for a function statement is:
Function Name( ... parameters ...) As ReturnType
The two function statements should end: As Long.
Issue 4
Consider: "ActiveWorkbook.Worksheets("RDBMergeSheet")"
If you are working on multiple workbooks, ActiveWorkbook is not enough. If you are only working on one workbook, ActiveWorkbook is unnecessary. Please do not work with multiple workbooks until your understanding of Excel VBA is better.
Issue 5
You delete worksheet "RDBMergeSheet" and then recreate it which hurts my soul. More importantly, you have lost the column headings. I will discuss this matter further under Redesign.
Replace:
Application.DisplayAlerts = False
On Error Resume Next
ActiveWorkbook.Worksheets("RDBMergeSheet").Delete
On Error GoTo 0
Application.DisplayAlerts = True
Set DestSh = ActiveWorkbook.Worksheets.Add
DestSh.Name = "RDBMergeSheet"
with:
Set DestSh = Worksheets("RDBMergeSheet")
With DestSh
.Range(.Cells(2, 1), .Cells(Rows.Count, Columns.Count)).EntireRow.Delete
End With
You use Rows.Count, With and Cells in your code so I will not explain them.
.Range(.Cells(RowTop, ColLeft), .Cells(RowBottom, ColRight)) is an easy method of specifying a range with the top left and bottom right cells.
I have used .EntireRow so I do not need the column numbers. The following gives the same effect:
.Rows("2:" & Rows.Count).EntireRow.Delete
As far as I know ClearContents (which some people favour) has the same effect as Delete. It certainly takes the same number of micro-seconds. For the usages above, both remove any values or formatting from the second row to the last row of the worksheet.
The above change means that row 1 is unchanged and the column widths are not lost. I do not need AutoFit which you have used.
Issue 6
Please be systematic in the naming of your variables. You use StartRow as the first row and shLast as the last row of the source worksheet and Last as the last row of the destination worksheet. Will a colleague who takes over maintenance of your macro find this easy to understand? Will you remember it in six months when this macro needs some maintenance?
Develop a naming system that works for you. Better still, get together with colleagues and agree a single system so all your employer's macros look the same. Document this system for the benefit of future staff. I would name these variables: RowNumDestLast, RowNumSrcStart and RowNumSrcLast. That is: <purpose of variable> <worksheet> <purpose within worksheet>. This system works for me but your system could be completely different. The key feature of a good system is that you can look at your code in a year and immediately know what each statement is doing.
Issue 7
If shLast > 0 And shLast >= StartRow Then
You set StartRow to 1 and never change it so if shLast >= StartRow then shLast > 0. The following is enough:
If shLast >= StartRow Then
Issue 8
If Last + CopyRng.Rows.Count > DestSh.Rows.Count Then
MsgBox "There are not enough rows in the " & _
"summary worksheet to place the data."
GoTo ExitTheSub
End If
It is good that you are checking for conditions that will result in fatal errors but is this the most likely error? Even if you are using Excel 2003, you have room for 65,535 people and a heading line. You will break the size limit on a workbook before you exceed the maximum number of rows.
Issue 9
Set CopyRng = sh.Range(sh.Rows(StartRow), sh.Rows(shLast))
This includes the heading row in the range to be copied. Since I will suggest a totally different method later, I will not suggest a correction.
Issue 10
With DestSh.Cells(Last + 1, "A")
.PasteSpecial xlPasteValues
.PasteSpecial xlPasteFormats
Why are you pasting the values and formats separately?
Redesign
With the corrections above, the code sort of works. With your source data, it sets the destination sheet to:
Age Name Dept
Name Age
Sathish 22
Sarathi 24
Age Name Dept
60 Saran Comp sce
31 Rajan B.com
This is not what you seek. So the rest of this answer is about design: how do you achieve the appearance you seek? There are many approaches but I offer one and explain why I have picked it without discussing alternatives.
Key issues:
How do you determine which columns to consolidate and in which sequence?
If there is a column in a source worksheet that you are not expecting, what do you do? Is someone collecting information for which there is no central interest or is the column name misspelt?
I have decided to use the existing column names within worksheet "RDBMergeSheet" to determine the sequence. To prepare the macro for a new column name, just add that name to "RDBMergeSheet". If I discover a column name in a source sheet that is not in "RDBMergeSheet", I add it on the right. This second decision will highlight the error if a column name is misspelt but will not be a benefit if someone is collecting extra information in a source worksheet.
I do not copy formats to worksheet "RDBMergeSheet" since, if the source worksheets are formatted differently, each part of worksheet "RDBMergeSheet" would be different.
New statements and explanations
Const RowFirstData As Long = 2
Const WShtDestName As String = "RDBMergeSheet"
A constant means I use the name in the code and can change the value by changing the Const statement.
I assume the first row of every worksheet contains column names and the first data row is 2. I use a constant to make this assumption clear. It would be possible to use this to write code that would handle a different number of heading rows but I have not done so because it would complicate the code for little advantage.
ColNumDestLast = .Cells(1, Columns.Count).End(xlToLeft).Column
.Cells(1, Columns.Count) identifies the last column of row 1 which I assume is blank. .End(xlToLeft) is the VBA equivalent of the keyboard Ctrl+Left. If .Cells(1, Columns.Count) is blank, .Cells(1, Columns.Count).End(xlToLeft) returns the first cell to the left which is not blank. .Column gives the column number of that cell. That is, this statement sets ColNumDestStart to the column number of the last cell in row 1 with a value.
ColHeadDest = .Range(.Cells(1, 1), .Cells(1, ColNumDestLast)).Value
This copies the values from row 1 to the variant array ColHeadDest. ColHeadDest will be redimensioned by this statement to (1 to 1, 1 to ColNumDestLast). The first dimension is for the rows, of which there is only one, and the second dimension is for the columns.
Replacement consolidate
I hope I have added enought comments for the code to make sense. You still need the corrected LastRow and LastCol. I could have replaced LastRow and LastCol but I think I have provided enough new code to be getting on with.
