Separación de datos de un archivo adjunto constantemente en un nuevo archivo

En lugar de usar una macro para exportar la tabla, simplemente puede crear un código para abrir el archivo y agregarle los datos.

Cómo usar

Simplemente copie el código a un módulo VBA en su aplicación y llámelo así:

' Export the Table "Orders" to "orders.csv", appending the data to the       '
' existing file if there is one.                                             '
ExportQueryToCSV "Orders", "C:\orders.csv", AppendToFile:=True

' Export the result of the query to "stock.csv" using tabs as delimiters     '
' and no header or quotes around strings                                     '
ExportQueryToCSV "SELECT * FROM Stock WHERE PartID=2", _
                 "C:\stock.csv", _
                 AppendToFile:=False, _
                 IncludeHeader:=False, _
                 Delimiter:=chr(9), _
                 QuoteString:=false

' Options are:                                                               '
' - AppendToFile : to append the record to the file if it exists instead of  ' 
'                  overwriting it (default is false)                         '
' - Delimiter    : what separator to use (default is the coma)               '
' - QuoteString  : Whether string and memo fields should be quoted           '
'                  (default yes)                                             '
' - IncludeHeader: Whether a header with the field names should be the first '
'                  line (default no)                                         '
' Some limitations and improvements:                                         '
' - Memo containing line returns will break the CSV                          '
' - better formatting for numbers, dates, etc                                '

Tenga en cuenta que no es perfecto y es posible que deba adaptar el código para reflejar cómo desea que se formatee la información, pero los valores predeterminados deberían estar bien en la mayoría de los casos.
