combining multiple workbooks into one worksheet - excel

Question

I am currently trying to get data recorded into excel workbooks to be automatically copied over onto one "mass data" sheet. The files are named by date ex. "5-28-17". There is one for each day of the month. I'd like to collect all data into one sheet, as previously stated, in order by date descending.
I am currently using this code which should place all of the different workbooks onto their own worksheet, but I am having issues with that as well.
Option Explicit
Const path As String = "C:\Users\dt\Desktop\dt kte\"
Sub GetSheets()
Dim FileName As String
Dim wb As Workbook
Dim sheet As Worksheet
FileName = Dir(path & "*.xls*")
Do While FileName <> ""
Set wb = Workbooks.Open(FileName:=path & FileName, ReadOnly:=True)
For Each sheet In wb.Sheets
sheet.Copy After:=ThisWorkbook.Sheets(1)
Next sheet
wb.Close
FileName = Dir()
Loop
End Sub
I am trying to do this with VBA. There are 15 columns in the sheets I'm pulling from and the sheet I want to copy to. All line up perfectly. Is there a way to move the sheets from the WB I'm currently working on which should contain a worksheet for each WB onto one mass worksheet? Or can I pull all data directly from the folder with all of the workbooks saved by date to one worksheet?

Answer 1

I would use this AddIn.

It will do what you want, and a whole lot more as well.

Consider using an MS Access database. Not to worry if you do not have the Office GUI .exe app installed. Because you use a Windows machine, you do have its Jet/ACE SQL Engine (.dll files).
CREATE DATABASE
Sub CreateDatabase()
On Error GoTo ErrHandle
Dim fso As Object, olDb As Object, db As Object
Const dbLangGeneral = ";LANGID=0x0409;CP=1252;COUNTRY=0"
Const strpath As String = "C:\Path\To\ExcelDatabase.accdb"
' CREATE DATABASE
Set fso = CreateObject("Scripting.FileSystemObject")
Set olDb = CreateObject("DAO.DBEngine.120")
If Not fso.FileExists(strpath) Then
Set db = olDb.CreateDatabase(strpath, dbLangGeneral)
End If
MsgBox "Successfully created database!", vbInformation
ExitSub:
Set db = Nothing: Set olDb = Nothing: Set fso = Nothing
Exit Sub
ErrHandle:
MsgBox Err.Number & " - " & Err.Description, vbCritical, "RUNTIME ERROR"
Resume ExitSub
End Sub
CREATE, POPULATE, EXPORT EXCEL TABLE (Excel files never opened)
Sub CreateTable()
On Error GoTo ErrHandle
Dim conn As Object, rst As Object
Dim constr As String, FileName As String, i As Integer
Const xlpath As String = "C:\Users\dt\Desktop\dt kte\"
Const accpath As String = "C:\Path\To\ExcelDatabase.accdb"
' CONNECT TO DATABASE
constr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & accpath & ";"
Set conn = CreateObject("ADODB.Connection")
conn.Open constr
i = 1
FileName = Dir(xlpath & "*.xls*")
Do While FileName <> ""
If i = 1 Then
' CREATE TABLE VIA MAKE TABLE QUERY
conn.Execute "SELECT * INTO MyExcelTable" _
& " FROM [Excel 12.0 Xml;HDR=Yes;" _
& " Database=" & xlpath & FileName & "].[Sheet1$]"
Else
' POPULATE VIA APPEND QUERY
conn.Execute "INSERT INTO MyExcelTable" _
& " SELECT * FROM [Excel 12.0 Xml;HDR=Yes;" _
& " Database=" & xlpath & FileName & "].[Sheet1$]"
End If
i = i + 1
FileName = Dir()
Loop
' EXPORT TO EXCEL
Set rst = CreateObject("ADODB.Recordset")
rst.Open "SELECT * FROM MyExcelTable", conn
ThisWorkbook.Worksheets("MASS_DATA").Range("A1").CopyFromRecordset rst
' CLOSE CONNECTION
rst.Close: conn.Close
MsgBox "Successfully created and populated table!", vbInformation
ExitSub:
Set rst = Nothing: Set conn = Nothing
Exit Sub
ErrHandle:
MsgBox Err.Number & " - " & Err.Description, vbCritical, "RUNTIME ERROR"
Resume ExitSub
End Sub
