Replace Worksheets content without opening it - excel

Question

I am using ADO model to gather data from various closes workbooks. This is working well.
I now want to put this data in another closed workbook, but I would like to be able to delete a sheet content before.
How can I delete a worksheet content without opening the workbook using VBA ?
How can I transfer a record set to a closed wb ? / Copy one table to another using ADO ?
EDIT :
I was able to insert some data from one workbook to another one in a new sheet but I can't get to output data in an existing worksheet.
When I try the INSERT INTO statement, an error is raised. Update impossible, database or object readonly.
Here is the code :
Sub tranfert()
Dim ExcelCn As ADODB.Connection
Dim ExcelRst As ADODB.Recordset
Dim Cn As New ADODB.Connection
Dim Rst As New ADODB.Recordset
Dim maBase As String, maFeuille As String
Dim maTable As String, NomClasseur As String
Dim nbEnr As Long
maBase = "C:\Users\Lichar\Documents\Base.xlsx"
maTable = "[table$]"
NomClasseur = "C:\Users\Lichar\Documents\Target.xlsx"
maFeuille = "Sheet2"
'Connection to base file
Cn.Open "Provider=Microsoft.ACE.OLEDB.12.0;" & _
"Data Source=" & maBase & ";" & _
"Extended Properties=""Excel 12.0;HDR=NO;"""
'Requète dans la table Access
Rst.Open "SELECT * FROM " & maTable, Cn
'Connection to target file
Set ExcelCn = New ADODB.Connection
ExcelCn.Open "Provider=Microsoft.ACE.OLEDB.12.0;" & _
"Data Source=" & NomClasseur & ";" & _
"Extended Properties=""Excel 12.0;HDR=NO;"""
'-----------------------------------------
'Create a new sheet and output data
Cn.Execute "SELECT * INTO [Excel 12.0;" & _
"Database=" & NomClasseur & "].[" & maFeuille & "] FROM " & maTable, nbEnr
'-----------------------------------------
'Trying to ouput data in existing sheet
'Cn.Execute "INSERT INTO [sheet$] IN '' [Excel 12.0;" & _
' "Database='" & NomClasseur & "'] SELECT * FROM " & maTable, nbEnr
Rst.Close
Cn.Close
Set ExcelRst = Nothing
Set ExcelCn = Nothing
**EDIT 2 **
I've found a partial solution using INSERT INTO. Here is a working code that takes data from source.xlsx in the table sheet and output it (or append) in target.xlsx in the sheet sheet :
Sub SQLQUERY()
Dim Cn As ADODB.Connection
Dim QUERY_SQL As String
Dim Rst As ADODB.Recordset
Dim ExcelCn As ADODB.Connection
Dim ExcelRst As ADODB.Recordset
SourcePath = "C:\Users\BVR\Documents\Source.xlsx"
TargetPath = "C:\Users\BVR\Documents\Target.xlsx"
CHAINE_HDR = "[Excel 12.0 MACRO;Provider=Microsoft.ACE.OLEDB.12.0;Mode=Read;Extended Properties='HDR=YES;'] "
Set Cn = New ADODB.Connection
STRCONNECTION = _
"Provider=Microsoft.ACE.OLEDB.12.0;" & _
"Data Source='" & SourcePath & "';" & _
"Mode=Read;" & _
"Extended Properties=""Excel 12.0 Macro;"";"
QUERY_SQL = _
"SELECT * FROM [table$] "
Cn.Open STRCONNECTION
Set ExcelCn = New ADODB.Connection
ExcelCn.Open "Provider=Microsoft.ACE.OLEDB.12.0;" & _
"Data Source=" & TargetPath & ";" & _
"Extended Properties=""Excel 12.0;HDR=NO;"""
Cn.Execute "INSERT INTO [sheet$] IN '" & TargetPath & "' 'Excel 12.0;' " & QUERY_SQL
'--- Fermeture connexion ---
Cn.Close
End Sub
I've noticed 2 problems. First If one of my field name contains a "." in it, the code will generate an error stating that INSERT INTO contains an unknown field name. This is problematic.
Second I cannot select only the columns I want. If I "SELECT [F1], [F2] ..." an error will raise stating that there is a circular reference. (I can however select the columns I want using field names)
