Dynamically Populate All Sheets in Excel Workbook to a Master Sheet - excel

Question

So I have a workbook with multiple sheets. All contain the same columns but just different categorical data. I want to grab all the data from those sheets and display/populate to a master sheet in the workbook.
I have tried different methods, but none of them are dynamic. The amount of data can be changed (+/-, either more rows or less rows) in each sheet. Each method I have found seems to be a static solution.
One example is to use the Consolidate option under the data tab, and add the respective reference/range for each sheet you would like to add (not dynamic).
Another option I found was a VBA macro, which populates the headers over and over, which I do not want to happen either, I want them all under the same header (Since the columns are already the same)
Sub Combine()
'UpdatebyExtendoffice20180205
Dim I As Long
Dim xRg As Range
Worksheets.Add Sheets(1)
ActiveSheet.Name = "Combined"
For I = 2 To Sheets.Count
Set xRg = Sheets(1).UsedRange
If I > 2 Then
Set xRg = Sheets(1).Cells(xRg.Rows.Count + 1, 1)
End If
Sheets(I).Activate
ActiveSheet.UsedRange.Copy xRg
Next
End Sub
Is this achievable?
Sheet 1
Sheet 2
Master Sheet Should Be:
But actually returns the following:
Will this constantly run each time the workbook is closed/opened/updated if it is a macro enabled workbook?

Answer 1

Consolidate All Worksheets
It is assumed that the Combined worksheet already exists with at least the headers which will stay intact.
To make it more efficient, only values are copied (no formats or formulas).
It will utilize the Worksheet Activate event: each time you activate (select) the combined worksheet, the data will automatically be updated.
Sheet Module of the Combined worksheet e.g. Sheet10(Combined)
Option Explicit
Private Sub Worksheet_Activate()
CombineToMaster
End Sub
Standard Module e.g. Module1
Option Explicit
Sub CombineToMaster()
Const dName As String = "Combined"
Dim wb As Workbook: Set wb = ThisWorkbook ' workbook containing this code
Dim dws As Worksheet: Set dws = wb.Worksheets(dName)
Dim drrg As Range
With dws.UsedRange
If .Rows.Count = 1 Then
Set drrg = .Offset(1)
Else
.Resize(.Rows.Count - 1).Offset(1).Clear
Set drrg = .Resize(1).Offset(1)
End If
End With
Dim sws As Worksheet
Dim srg As Range
Dim drg As Range
Dim rCount As Long
For Each sws In wb.Worksheets
If sws.Name <> dName Then
With sws.UsedRange
rCount = .Rows.Count - 1
If rCount > 0 Then
Set srg = .Resize(rCount).Offset(1)
drrg.Resize(rCount).Value = srg.Value
Set drrg = drrg.Offset(rCount)
End If
End With
End If
Next sws
End Sub

Answer 2

VBA Solution
Sub Combine()
Dim wsCombine As Worksheet: Set wsCombine = GetSheetCombine
Dim dataSheets As Collection: Set dataSheets = GetDataSheets
' Copy Header
dataSheets.Item(1).UsedRange.Rows(1).Copy
wsCombine.Range("A1").PasteSpecial xlPasteAll
wsCombine.Range("A1").PasteSpecial xlPasteColumnWidths
Application.CutCopyMode = False
' Copy data
Dim rngDest As Range: Set rngDest = wsCombine.Range("A2")
Dim srcRng As Range
Dim ws As Worksheet
For Each ws In dataSheets
' Drop header row
With ws.UsedRange
Set srcRng = .Offset(1, 0).Resize(.Rows.Count - 1)
End With
srcRng.Copy rngDest
Set rngDest = rngDest.Offset(srcRng.Rows.Count)
Next ws
Application.CutCopyMode = False
MsgBox "Done!", vbInformation
End Sub
Private Function GetSheetCombine() As Worksheet
Dim ws As Worksheet
With Worksheets
On Error Resume Next
Set ws = .Item("Combine")
On Error GoTo 0
If ws Is Nothing Then
Set ws = .Add(Before:=.Item(1))
ws.Name = "Combine"
Else
ws.Cells.Clear ' clear any existing data
End If
End With
Set GetSheetCombine = ws
End Function
Private Function GetDataSheets() As Collection
Dim Result As New Collection
Dim ws As Worksheet
For Each ws In Worksheets
If ws.Name <> "Combine" Then Result.Add ws
Next ws
Set GetDataSheets = Result
End Function
As to your question "Will this run every time macro enabled workbook is open?".
No. You will need to put this in a VBA module and run it every time you need, via the Macro dialog (View->Macros), or link a button to it.
