Excel vba: combine multiple files in one sheet - vba

Question

I have 100+ files in one folder. Each file has 3 lists, but only 1 list with data. I need to take that data from each file and combine it in a single file on 1 list. I wrote a sub for it, but I'm not sure how to go around selecting only the range needed (it varies from file to file) - in the same way you do it on keyboard with Ctrl + Shift + left arrow + down arrow. And how should I go around pasting it in the result workbook at exactly the first free line after the data that was pasted before?
Sub combine()
Application.ScreenUpdating = False
Application.DisplayAlerts = False
Application.Calculation = xlCalculationManual
Dim ExcelApp As Object
Set ExcelApp = CreateObject("Excel.Application")
ExcelApp.Visible = False
ExcelApp.ScreenUpdating = False
ExcelApp.DisplayAlerts = False
ExcelApp.EnableEvents = False
'**VARIABLES**
Dim folderPath As String
folderPath = "Y:\plan_graphs\final\mich_alco_test\files\"
'COUNT THE FILES
Dim totalFiles As Long
totalFiles = 0
Dim fileTitle As String
fileTitle = Dir(folderPath & "*.xl??")
Do While fileTitle <> ""
totalFiles = totalFiles + 1
fileTitle = Dir()
Loop
'OPENING FILES
Dim resultWorkbook As Workbook
Dim dataWorkbook As Workbook
Set resultWorkbook = ExcelApp.Application.Workbooks.Open("Y:\plan_graphs\final\mich_alco_test\result.xlsx")
fileTitle = Dir(folderPath & "*.xl??")
'FOR EACH FILE
Do While fileTitle <> ""
Set dataWorkbook = ExcelApp.Application.Workbooks.Open(folderPath & fileTitle)
dataWorkbook.Worksheets("List1").Range("A1").Select
dataWorkbook.Worksheets("List1").Selection.CurrentRegion.Select
`resultWorkbook.Range
fileTitle = Dir()
Loop
ExcelApp.Quit
Set ExcelApp = Nothing
End Sub

Answer 1

I may have misunderstood the question and unfortunately I cannot make a comment. If I've grasped this question wrong, i'll delete.
but I'm not sure how to go around selecting only the range needed
This suggests that you have a dynamic amount of data and want to use Range to grab the selections.
Supposing you know the column location of where said data is located (in this case my list starts at B2 and we don't know where it ends. You can use Range to dynamically select all data:
Dim rcell As Range
Dim rng As Range
Set rng = ActiveSheet.Range("B2", Range("B2").End(xlDown))
For Each rcell In rng.Cells
Debug.Print rcell.Value
Next rcell
End Sub
First we define a Range variable and assign it to the range starting at B2 and using .End(xlDown) we can select a range ending at the final entry.
For further reading on .End() see here.
Hope this helps.

You can do this without VBA. Use Get & Transform instead.
Here are a few steps to get you started:
Go to the Data Tab
Under Get & Transform, pick New Query - From File - From Folder
Select the folder containing all your 100+ files
Select the tab that contains your data
You are almost there. Do your final fixes (if needed)
Once you're done, click Close & Load

Answer 3

This should do what you want.
