I receive the time data in seconds and format it in a query to Format([Dials and TT_week].[TT In]/86000),"hh:nn:ss" to get it to show as Hours:minutes:seconds.
The results look like this

I then use the following code to split the results into separate spreadsheets for each manager.
Code:
Option Compare Database
Function split_export()
Dim dbs As DAO.Database
Dim strSQL As String
Dim rs As DAO.Recordset
On Error Resume Next
Kill "C:\Automation\Aspect_Reports\*.xl*"
On Error GoTo 0
Set dbs = CurrentDb
strSQL = "SELECT DISTINCT [Manager] FROM qry_Monthly_Export_Final " & "ORDER BY [Manager]"
Set rs = dbs.OpenRecordset(strSQL, dbOpenDynaset)
While Not rs.EOF
strSQL = "SELECT * FROM qry_Monthly_Export_Final " _
& "WHERE [Manager] = '" & rs("Manager") & "'"
dbs.QueryDefs("qry_ExportCopy_Final").SQL = strSQL
DoCmd.TransferSpreadsheet acExport, acSpreadsheetTypeExcel12Xml, _
"qry_ExportCopy_Final", _
"C:\Automation\Aspect_Reports\" & rs("Manager") & ".xlsx"
rs.MoveNext
Wend
rs.Close
Set rs = Nothing
End Function
Then I use the following code to open each worksheet that was created from the step above and bold the header, autofit the column and subtotal on Column 2
Code:
Option Compare Database
Function split_Update()
Dim dbs As DAO.Database
Dim MyPath As String, FilesInPath As String
Dim MyFiles() As String, Fnum As Long
Dim mybook As Workbook
Dim CalcMode As Long
Dim sh As Worksheet
Dim ErrorYes As Boolean
Dim rng As Range
Dim cell As Range
Set dbs = CurrentDb
'Fill in the path\folder where the files are
MyPath = "C:\Automation\Aspect_Reports"
'Add a slash at the end if the user forget it
If Right(MyPath, 1) <> "\" Then
MyPath = MyPath & "\"
End If
'If there are no Excel files in the folder exit the sub
FilesInPath = Dir(MyPath & "*.xl*")
If FilesInPath = "" Then
MsgBox "No files found"
End If
'Fill the array(myFiles)with the list of Excel files in the folder
Fnum = 0
Do While FilesInPath <> ""
Fnum = Fnum + 1
ReDim Preserve MyFiles(1 To Fnum)
MyFiles(Fnum) = FilesInPath
FilesInPath = Dir()
Loop
'Change ScreenUpdating, Calculation and EnableEvents
With Application
' .Calculation = xlCalculationManual
' .ScreenUpdating = False
'.EnableEvents = False
End With
'Loop through all files in the array(myFiles)
If Fnum > 0 Then
For Fnum = LBound(MyFiles) To UBound(MyFiles)
Set mybook = Nothing
On Error Resume Next
Set mybook = Workbooks.Open(MyPath & MyFiles(Fnum))
On Error GoTo 0
If Not mybook Is Nothing Then
'Change cell value(s) in one worksheet in mybook
On Error Resume Next
With mybook.Worksheets(1)
If .ProtectContents = False Then
ActiveSheet.Range("1:1").Font.Bold = True
ActiveSheet.Range("1:1").EntireColumn.AutoFit
Selection.TextToColumns DataType:=xlDelimited
Selection.Subtotal GroupBy:=2, Function:=xlSum, TotalList:=Array(4, 5, 6, 7, 8, 9, 10)
Else
ErrorYes = True
End If
End With
If Err.Number > 0 Then
ErrorYes = True
Err.Clear
'Close mybook without saving
mybook.Close savechanges:=False
Else
'Save and close mybook
mybook.Close savechanges:=True
End If
On Error GoTo 0
Else
'Not possible to open the workbook
ErrorYes = True
End If
Next Fnum
End If
If ErrorYes = True Then
MsgBox "There are problems in one or more files, possible problem:" _
& vbNewLine & "protected workbook/sheet or a sheet/range that not exist"
End If
'Restore ScreenUpdating, Calculation and EnableEvents
With Application
'.ScreenUpdating = True
'.EnableEvents = True
'.Calculation = CalcMode
End With
End Function
It all works as expected except the time columns. They come in looking like this. Basically the subtotals for the time columns are 0 instead of the sum of the times.

In playing around in Excel, if I go to Text to Columns, choose delimited, remove all delimiters and hit finish it then totals the time showing it in seconds. Then I format the field to hh:mm:ss and it displays the results as I would expect.
Is there a way to do the text to columns and formatting bit at the same time it is bolding the first line and subtotaling the worksheets? Or is there a better way to do this?
Thanks in advance
