Calculate totals from highlighted cell in Excel file from ms access

>>I have an access query that I output to an excel spreadsheet
>>So I thought about having code in access to create a new module with the function in excel.

What's the method you're using to export the access query to Excel? We probably need to format the excel file after it's exported.

Here is the code for doing the export - I have a button that the user clicks - it exports the query to spreadsheet - then formats the open spreadsheet:


Private Sub btnAEC_Click()

'Export AEC AP spreadsheet
On Error Resume Next

Forms![AP_Aging]![SORT] = "00"

DoCmd.SetWarnings False

DoCmd.OpenQuery "AP_Aging_MT"

DoCmd.OpenQuery "AP_Aging_Totals_CT"

DoCmd.OpenQuery "AP_Aging_Totals_MT"

DoCmd.OpenQuery "AP_Aging_Subtotals_MT"

DoCmd.OpenQuery "AP_Aging_Report_Final_MT"

DoCmd.OpenQuery "AP_Aging_Grand_Totals_Append"

DoCmd.SetWarnings True

Dim filePath As String
Dim xl As Excel.Application
Dim xlBook As Excel.Workbook
Dim xlSheet As Excel.Worksheet
On Error Resume Next

    DoCmd.OutputTo acOutputQuery, "AP_Aging_Report_Export", acFormatXLSX, "AP_Aging-AEC.xlsx"

    Application.SetOption "Show Status Bar", True

    '========Formating VBA=========

    filePath = "c:\temp\AP_Aging-AEC.xlsx"

    Set xl = New Excel.Application

    Set xlBook = xl.Workbooks.Open("AP_Aging-AEC.xlsx")

    Set xlSheet = xlBook.Worksheets(1)

    xl.Visible = True

    With xlSheet
     
       
        For Each c In .Range(.Range("B1"), .Range("B" & .Rows.Count).End(xlUp))
            If Left(c, 6) = "Totals" Then
                c.EntireRow.Font.Bold = True
                .Range(c, c.Offset(0, 12)).Interior.ColorIndex = 8
               
            End If
        Next
       
       
         For Each c In .Range(.Range("A1"), .Range("A" & .Rows.Count).End(xlUp))
            If Right(c, 5) = "Total" Then
                c.EntireRow.Font.Bold = True
                .Range(c, c.Offset(0, 13)).Interior.ColorIndex = 4
               
            End If
        Next
       
       

        .Rows("1:1").Font.Bold = True
        .Range("A1").AutoFilter
        .Cells.Columns.AutoFit
       
       
    End With
   
    With xl
        .Goto xlSheet.Range("A1"), True
        .Goto xlSheet.Range("A2"), False
        .ActiveWindow.FreezePanes = True
        .Range("A1").Select
    End With


End Sub

Once you have exported the data to Excel and the user is interacting with it, what does it have to do with Access?  The code you need must go into a macro in Excel.  You can create a template and from Access, instead of creating a new workbook from scratch, you can copy the template and insert the data.  That way the macro will already be there.  Or, you can have Access create the macro by inserting it after it populates the data.

do you have a sample of AP_Aging-AEC.xlsx can share with us? (with crucial data masked)

...or do a similar web search of:
"Excel Sum colored cells"
or
"Excel Sum based on color"
ex:
https://www.google.com/?gws_rd=ssl#q=Excel+sum+cells+based+on+color

The CFO has a specific amount of cash each day he can use to pay past due bills.  He wants to highlight cells yellow that he is thinking about paying and show a running total so he see how much cash is left as he pick cells to pay.

When he is done he is going to send the sheet to the payable clerk - she will see the yellow cells and that will be the bills she will pay.

So was able to set up a excel sheet with a module and code to calculate a running total for all yellow highlighted cells.  So I looked at trying to take the code above to do the formating to an existign excel macro-enabled template.

Could not find a way to do this.

Any suggestion on how this could be done?  

I did some searching on sending access queries to excel templates - but could not find information on sending access query to macro-enabled templates.

Glad I could help...
