Recreate Source Data from PivotTable Cache - excel

Question

I am trying to extract the source data from a PivotTable that uses a PivotTable cache and place it into a blank spreadsheet. I tried the following but it returns an application-defined or object defined error.
ThisWorkbook.Sheets.Add.Cells(1,1).CopyFromRecordset ThisWorkbook.PivotCaches(1).Recordset
Documentation indicates that PivotCache.Recordset is an ADO type, so this ought to work. I do have the ADO library enabled in references.
Any suggestions on how to achieve this?

Answer 1

Unfortunately, there appears to be no way to directly manipulate PivotCache in Excel.
I did find a work around. The following code extracts the the pivot cache for every pivot table found in a workbook, puts it into a new pivot table and creates only one pivot field (to ensure that all rows from the pivot cache are incorporated in the total), and then fires ShowDetail, which creates a new sheet with all of the pivot table's data in.
I would still like to find a way to work directly with PivotCache but this gets the job done.
Public Sub ExtractPivotTableData()
Dim objActiveBook As Workbook
Dim objSheet As Worksheet
Dim objPivotTable As PivotTable
Dim objTempSheet As Worksheet
Dim objTempPivot As PivotTable
If TypeName(Application.Selection) <> "Range" Then
Beep
Exit Sub
ElseIf WorksheetFunction.CountA(Cells) = 0 Then
Beep
Exit Sub
Else
Set objActiveBook = ActiveWorkbook
End If
With Application
.ScreenUpdating = False
.DisplayAlerts = False
End With
For Each objSheet In objActiveBook.Sheets
For Each objPivotTable In objSheet.PivotTables
With objActiveBook.Sheets.Add(, objSheet)
With objPivotTable.PivotCache.CreatePivotTable(.Range("A1"))
.AddDataField .PivotFields(1)
End With
.Range("B2").ShowDetail = True
objActiveBook.Sheets(.Index - 1).Name = "SOURCE DATA FOR SHEET " & objSheet.Index
objActiveBook.Sheets(.Index - 1).Tab.Color = 255
.Delete
End With
Next
Next
With Application
.ScreenUpdating = True
.DisplayAlerts = True
End With
End Sub

Go to the Immediate Window and type
?thisworkbook.PivotCaches(1).QueryType
If you get something other than 7 (xlADORecordset), then the Recordset property does not apply to this type of PivotCache and will return that error.
If you get an error on that line, then your PivotCache is not based on external data at all.
If your source data comes from ThisWorkbook (i.e. Excel data), then you can use
?thisworkbook.PivotCaches(1).SourceData
To create a range object and loop through it.
If your QueryType is 1 (xlODBCQuery), then SourceData will contain the connection string and commandtext for you to create and ADO recordset, like this:
Sub DumpODBCPivotCache()
Dim pc As PivotCache
Dim cn As ADODB.Connection
Dim rs As ADODB.Recordset
Set pc = ThisWorkbook.PivotCaches(1)
Set cn = New ADODB.Connection
cn.Open pc.SourceData(1)
Set rs = cn.Execute(pc.SourceData(2))
Sheet2.Range("a1").CopyFromRecordset rs
rs.Close
cn.Close
Set rs = Nothing
Set cn = Nothing
End Sub
You need the ADO reference, but you said you already have that set.

Answer 3

I found myself having the same problem, needing to scrape programmatically data coming different Excels with cached Pivot data.
Although the topic is a bit old, still looks there is no direct way to access the data.
Below you can find my code, which is a more generalized refinement of the already-posted solution.
The major difference is the filter removal from fields, as sometimes pivot comes with filters on, and if you call .Showdetail it will miss filtered data.
I use it to scrape from different file format without having to open them, it is serving me quite well thus far.
Hope it is useful.
