VBA-ADODB.Connection从Excel读取

Question

Does using ADODB.Connection to read data from Excel files actually open the excel files?

Is there a performance benefit from using ADODB vs opening the file through VBA using GetObject() and reading the data (with screen updating = false)?

GetObject() seems to sometime take a while to open the file depending on the file. I would like a more "lightweight" alternative to pulling data from the excel file.

Unless you need the functionalities inherent to Excel, I would usually go with an ADO connection.

Dim cn as ADODB.Connection
Set cn = New ADODB.Connection
With cn
    .Provider = "Microsoft.Jet.OLEDB.4.0"
    .ConnectionString = "Data Source=C:\MyFolder\MyWorkbook.xls;" & _
"Extended Properties=Excel 8.0;"
    .Open
End With
