Column headers to new sheet - vba

Question

I am trying to use a file picker, which I have and then get the columns of every file and every sheet within that file into a new sheet. So A1 would have file name,B1 sheet name, C1 and down would have column headers (which are A1:?? in all the files Im picking).
Also some files are large so would having automatic calculation to automatic be helpful?
Also note that I have extra variables in the beggining but not necessarily used.
Here is the code, its a mess:
Sub ColumnHeaders()
'includes filling down
'Skips unreadable files
Dim wb As Workbook, fileNames As Object, errCheck As Boolean
Dim ws As Worksheet, wks As Worksheet, wksSummary As Worksheet
Dim y As Range, intRow As Long, i As Integer
Dim r As Range, lr As Long, myrg As Range, z As Range
Dim boolWritten As Boolean, lngNextRow As Long
Dim intColNode As Integer, intColScenario As Integer
Dim intColNext As Integer, lngStartRow As Long
Dim lngLastNode As Long, lngLastScen As Long
'Skipped worksheet for file names
Dim wksSkipped As Worksheet
Set wksSkipped = ThisWorkbook.Worksheets("Skipped")
' Turn off screen updating and automatic calculation
With Application
.ScreenUpdating = False
.Calculation = xlCalculationManual
End With
' Create a new worksheet, if required
On Error Resume Next
Set wksSummary = ActiveWorkbook.Worksheets("Headers")
On Error GoTo 0
If wksSummary Is Nothing Then
Set wksSummary = ActiveWorkbook.Worksheets.Add(After:=ActiveWorkbook.Worksheets(ActiveWorkbook.Worksheets.Count))
wksSummary.Name = "headers"
End If
' Set the initial output range, and assign column headers
With wksSummary
Set y = .Cells(.Rows.Count, 3).End(xlUp).Offset(1, 0)
Set r = y.Offset(0, 1)
Set z = y.Offset(0, -2)
lngStartRow = y.Row
.Range("A1:C1").Value = Array("File Name", "Sheet Name", "headers")
End With
'get user input for files to search
Set fileNames = CreateObject("Scripting.Dictionary")
errCheck = UserInput.FileDialogDictionary(fileNames)
If errCheck Then
Exit Sub
End If
'''
For Each Key In fileNames 'loop through the dictionary
On Error Resume Next
Set wb = Workbooks.Open(fileNames(Key))
If Err.Number <> 0 Then
Set wb = Nothing ' or set a boolean error flag
End If
On Error GoTo 0 ' or your custom error handler
If wb Is Nothing Then
wksSkipped.Cells(wksSkipped.Cells(wksSkipped.Rows.Count, "A").End(xlUp).Row + 1, 1) = fileNames(Key)
Else
Debug.Print "Successfully loaded " & fileNames(Key)
wb.Application.Visible = False 'make it not visible
' more working with wb
Code should go in here
wb.Close savechanges:=False 'close the workbook do not save
Set wb = Nothing 'release the object
End If
Next 'End of the fileNames loop
Set fileNames = Nothing
' Autofit column widths of the report
wksSummary.Range("A1:C1").EntireColumn.AutoFit
' Reset system settings
With Application
.Calculation = xlCalculationAutomatic
.ScreenUpdating = True
.Visible = True
End With
End Sub
I have the picker(a separate function) , I a skipped worksheet incase the file is corrupt, but I obviously am missing the part where to get the headers and sheet names.
Can anyone help?

Answer 1

When you open a workbook it becomes active so you'll need to create an object that will be the sheet that you are writing to. Somewhere at the top.
Dim wsReport As Excel.Worksheet
Set wsReport = ActiveWorkbook.Sheets("Sheet1") 'Whatever sheet you want to write to
Code to write out the data. Insert where you put "Code should go in here"
Dim iIndex As Integer
Dim lCol As Long
Dim lRow As Long
Dim lOutputCol As Long
lRow = 1
'Loop through the worksheets in the current workbook.
For iIndex = 1 To wb.Worksheets.count
'Set the current worksheet
Set ws = Application.Worksheets(iIndex)
'List out the workbook and worksheet names
wsReport.Range("A" & lRow).Value = wb.name
wsReport.Range("B" & lRow).Value = ws.name
'Start a counter of the columns that we are writing to
lOutputCol = 3
'Loop through the columns.
For lCol = 1 To ws.UsedRange.Columns.count
'Write the header
wsReport.Range(Col_Letter(lOutputCol) & lRow).Value = ws.Range(Col_Letter(lCol) & "1").Value
'Increment our column counters.
lOutputCol = lOutputCol + 1
Next lCol
'Increment the row we are writing to
lRow = lRow + 1
Next iIndex
And you'll need to add this function
Function Col_Letter(lngCol As Long) As String
Dim vArr
vArr = Split(Cells(1, lngCol).Address(True, False), "$")
Col_Letter = vArr(0)
End Function
