How do I copy info based on headers across Excel worksheets? - excel

Question

I was reviewing the following code:
Sub Combine()
Dim J As Integer
On Error Resume Next
Sheets(1).Select
Worksheets.Add
Sheets(1).Name = "Combined"
Sheets(2).Activate
Range("A1").EntireRow.Select
Selection.Copy Destination:=Sheets(1).Range("A1")
For J = 2 To Sheets.Count
Sheets(J).Activate
Range("A1").Select
Selection.CurrentRegion.Select
Selection.Offset(1, 0).Resize(Selection.Rows.Count - 1).Select
Selection.Copy Destination:=Sheets(1).Range("A65536").End(xlUp)(2)
Next
End Sub
This code combines cells for reporting. This is supposed to copy the info from all the sheets to one combined sheet. However, if I have different headers i.e if in Sheet1!A1 is "Address" and in Sheet2!A1 is "Name", it will copy the names under the address.
Is there a way to have some sort of search so that it will only copy the exact headers and paste them under the correct one?

Answer 1

Here's an example...
Option Explicit
Sub CombineData()
'--combines data from all sheets
' assumes all sheets have exact same header fields as the
' first sheet; however the fields may be different order.
'--combines using copy-paste. could be modified to pasteValues only
Dim lNdxSheet As Long, lNextRow As Long, lDestCol As Long
Dim lColCount As Long, lRowCount As Long
Dim rHeaders As Range
Dim sHeader As String
Dim vMatch As Variant, vHeaders As Variant
Dim wksCombined As Worksheet
With Application
.ScreenUpdating = False
.DisplayAlerts = False
End With
'--add new sheet for results
Set wksCombined = Worksheets.Add(Before:=Worksheets(1))
'--optional: delete existing sheet "Combined"
On Error Resume Next
Sheets("Combined").Delete
On Error GoTo 0
With wksCombined
.Name = "Combined"
'--copy headers that will be used in destination sheet
Set rHeaders = Sheets(2).Range("A1").CurrentRegion.Resize(1)
rHeaders.Copy Destination:=.Range("A1")
End With
'--read headers into array
vHeaders = rHeaders.Value
lColCount = UBound(vHeaders, 2)
lNextRow = 2
For lNdxSheet = 2 To Sheets.Count
'--count databody rows of continguous dataset at A1
lRowCount = Sheets(lNdxSheet).Range("A1").CurrentRegion.Rows.Count - 1
If lRowCount > 0 Then
For lDestCol = 1 To lColCount
sHeader = vHeaders(1, lDestCol)
'--search entire first col in case field is rSourceData
vMatch = Application.Match(sHeader, Sheets(lNdxSheet).Range("1:1"), 0)
If IsError(vMatch) Then
MsgBox "Header: """ & sHeader & """ not found on sheet: """ _
& Sheets(lNdxSheet).Name
GoTo ExitProc
End If
With Sheets(lNdxSheet)
'--copy-paste this field under matching field in combined
.Cells(2, CLng(vMatch)).Resize(lRowCount).Copy
' Option 1: paste values only
wksCombined.Cells(lNextRow, lDestCol).PasteSpecial (xlPasteValues)
' Option 2: paste all including formats and formulas
' wksCombined.Cells(lNextRow, lDestCol).PasteSpecial (xlPasteAll)
End With
Next lDestCol
lNextRow = lNextRow + lRowCount
End If ' lRowCount > 0
Next lNdxSheet
ExitProc:
With Application
.ScreenUpdating = True
.DisplayAlerts = True
End With
End Sub
