Make table of Excel spreadsheets and tabs from a folder

Hello EE,
* I need to have Access create a table that lists the filename, filedate, filesize, filepath for a given folder for Excel, Text, and CSV files.  (This example please use c:\IncomingData.)
* I also need a way to identify and import multiple tabs within the same Excel file.  I imagine that there would be a separate table for each Excel file with a row for each tab.

I will be using the above to import the contents of these files (and tabs) into one table that has the column headers of Field01, Field02, Field03, etc.  Based on the Filename (and tab name for Excel) I have a schema table that identifies the contents of each field for further processing.

I appreciate any help in getting this information into Access.

Thank you,
LVBarnes

For the first step:
1. Create a table (tblFiles) with fields: FileName(Text), FileDate(Text),FileSize(Number-Long Integer), and FilePath.
2. In a code module, add the code in the snippet.
3. Place your cursor in the code and run it (F5).
Public Function GetFileData()
    Dim fso As New Scripting.FileSystemObject
    Dim fil As Scripting.File, fld As Scripting.Folder
    Dim strSQL As String
    ' if the folder exists,
    If fso.FolderExists("C:\IncomingData") Then
        ' set the folder
        Set fld = fso.GetFolder("C:\IncomingData")
        ' loop through the files in the folder,
        For Each fil In fld.Files
            ' if the file is one of the target types,
            If LCase(Right(fil.Name, 3)) = "xls" Or LCase(Right(fil.Name, 3)) = "txt" Or _
              LCase(Right(fil.Name, 3)) = "csv" Then
                ' add the file to the table
                strSQL = "INSERT INTO tblFiles (FileName, FileDate, FileSize, FilePath) " & _
                    "VALUES ('" & fil.Name & "', '" & fil.DateCreated & "', " & fil.Size & _
                    ", '" & fil.Path & "')"
                CurrentProject.Connection.Execute strSQL
            End If
        Next fil
    End If
End Function

Will the Excel tabs already have tables or must you create the tables as you identify the tabs?
For the second step:
1. Create a table (tblTabs:  FileName(Text), FilePath(Text).
2. In a code module, add the code in the snippet.
3. Place your cursor in the code and run it (F5).
Public Function GetTabs()
    Dim rst As New ADODB.Recordset, strSQL As String
    Dim strFile As String, strTab As String
    Dim xl As Object, sheet As Object
    Set xl = CreateObject("Excel.Application")
    With rst
        .Open "SELECT FileName, FilePath FROM tblFiles", _
            CurrentProject.Connection, adOpenStatic, adLockReadOnly
        Do While Not .EOF
            ' if this file is an Excel file,
            If LCase(Right(.Fields("FileName"), 3)) = "xls" Then
                xl.Workbooks.Open .Fields("FilePath")
                For Each sheet In xl.ActiveWorkbook.Sheets
                    strSQL = "INSERT INTO tblTabs (FileName, TabName) " & _
                        "VALUES ('" & .Fields("FileName") & "', '" & sheet.Name & "')"
                    CurrentProject.Connection.Execute strSQL
                Next sheet
                xl.ActiveWorkbook.Close
                xl.Application.Quit
            End If
            .MoveNext
        Loop
        .Close
    End With
End Function

Open in new window

For the third step:
1. Import your text/comma separated file manually and create an import specification.
2. In a code module, add the code in the snippet.
3. Change "TableName" in the code to the name of the table you will import into.
4. Change "SpecName" in the code to the name of the specification you created in step 1.
5. Place your cursor in the code and run it (F5).

Please let me know if you have any questions.
Public Function ImportFiles()
    Dim strSQL As String, rst As New ADODB.Recordset
    strSQL = "SELECT tblFiles.FileName, tblFiles.FilePath, tblTabs.TabName " & _
        "FROM tblFiles LEFT JOIN tblTabs ON tblFiles.FileName = tblTabs.FileName;"
    With rst
        .Open strSQL, CurrentProject.Connection, adOpenStatic, adLockReadOnly
        Do While Not .EOF
            ' if this is an Excel file,
            If LCase(Right(.Fields("FileName"), 3)) = "xls" Then
                ' import the this worksheet to the table
                DoCmd.TransferSpreadsheet acImport, acSpreadsheetTypeExcel9, _
                    "TableName", .Fields("FilePath"), False, .Fields("TabName")
            ' else, if this is not an Excel file,
            Else
                ' import the text file to the table
                DoCmd.TransferText acImportDelim, "SpecName", "TableName", _
                    .Fields("FilePath"), False
            End If
            .MoveNext
        Loop
        .Close

<Will the Excel tabs already have tables or must you create the tables as you identify the tabs?>

Users are currently merging the contents of all the tabs on a spreadsheet onto one tab, and then uploading the merged tab into the same table.  (They currently do this with over 200 spreadsheets/textfiles manually!)  So all of the updates are going into the same table.  I'm using the Filename, TabName, FilePath, FileDate, to keep track of the data's original source.

Thank you for the post, I'll be trying this out shortly.
Hello CWood,

First and Second step are perfect.  I think I missed something on the third step as I'm getting Run-time error '3011' where the jet engine cannot find the first tab in the spreadsheet.  I've pasted the code I used for this step.  I have also opened tblFiles and tblTabs and verified that the filename is the same in both locations.

I've gone over it a few times, hopefully you will see that I missed.
Thank you,
LVBarnes



Public Function ImportFiles()
    Dim strSQL As String, rst As New ADODB.Recordset
    strSQL = "SELECT tblFiles.FileName, tblFiles.FilePath, tblTabs.TabName " & _
        "FROM tblFiles LEFT JOIN tblTabs ON tblFiles.FileName = tblTabs.FileName;"
    With rst

Please add the code shown in the snippet and check the tab name in the Immediate window (Ctrl+G) and compare it against the tab name in the Excel file.
Public Function ImportFiles()
    Dim strSQL As String, rst As New ADODB.Recordset
    strSQL = "SELECT tblFiles.FileName, tblFiles.FilePath, tblTabs.TabName " & _
        "FROM tblFiles LEFT JOIN tblTabs ON tblFiles.FileName = tblTabs.FileName;"
    With rst
        .Open strSQL, CurrentProject.Connection, adOpenStatic, adLockReadOnly
        Do While Not .EOF
            ' if this is an Excel file,
            If LCase(Right(.Fields("FileName"), 3)) = "xls" Then
                ' import the this worksheet to the table
' === ADD CODE ============================
Debug.Print "TabName:" & .Fields("TabName")
'==========================================
                DoCmd.TransferSpreadsheet acImport, acSpreadsheetTypeExcel9, _
                    "tblImport", .Fields("FilePath"), False, .Fields("TabName")
            ' else, if this is not an Excel file,
            Else
                ' import the text file to the table
                DoCmd.TransferText acImportDelim, "ImportSpec1", "tblImport", _
                    .Fields("FilePath"), False
            End If
            .MoveNext
        Loop
        .Close
    End With
End Function

Open in new window

Immediate window = TabName.Sheet1
Spreadsheet First Tab = Sheet1
Please try this:
1. Delete any data in your tblTabs table.
2. Replace the GetTabs function with the one in the snippet.
3. Run this function.
4. Change the fields in the tblImport table to F1, F2, etc.
5. Run the ImportFiles function.

The range in the DoCmd.TransferSpreadsheet method (the last attribute) requires a range of cells in addition to the tab name. Sorry I missed that.
Public Function GetTabs()
    Dim rst As New ADODB.Recordset, strSQL As String
    Dim strFile As String, strTab As String
    Dim xl As Object, sheet As Object, rng As Object
    Set xl = CreateObject("Excel.Application")
    With rst
        .Open "SELECT FileName, FilePath FROM tblFiles", _
            CurrentProject.Connection, adOpenStatic, adLockReadOnly
        Do While Not .EOF
            ' if this file is an Excel file,
            If LCase(Right(.Fields("FileName"), 3)) = "xls" Then
                xl.Workbooks.Open .Fields("FilePath")
                For Each sheet In xl.ActiveWorkbook.Sheets
                    Set rng = sheet.UsedRange
                    strSQL = "INSERT INTO tblTabs (FileName, TabName) " & _
                        "VALUES ('" & .Fields("FileName") & "', '" & sheet.Name & _
                        "!" & rng.Address(False, False) & "')"
                    CurrentProject.Connection.Execute strSQL
                Next sheet
                xl.ActiveWorkbook.Close
                xl.Application.Quit
            End If
            .MoveNext
        Loop
        .Close

First let me say that you are incredible and your directions are clear and concise and we are sooo close.

It looks like there is one small thing to work around.  tblImport originally had fields named Field01, Field02, Field03, etc.  I renamed them to F1, F2, F3... and the Excel spreadsheet imported correctly (all of the tabs.)  Once the spreadsheets were completed I received another Error code saying that Field01 was not available.  I think the Transferspreadsheet is looking for F1, F2, F3 and the TransferText is looking for Field01, Field02, Field03.  Go figure.

I could have each file type transfer to its own table and then merge them together if there is no programmitic setting that would solve the above.  What do you think?
