Excel 2000
Hello, I can't pull all the data I need because the ADO method looks for a header and if one isn't available, it pulls a blank. I know what rows I need so I make those the "SourceRange." I need to get data from an extremely large Excel file (40,000 rows and thru HH in columns) without opening it - I'm trying to speed up the process. Someone suggested I use ADO and now I'm slowly learning it. I am very good at spreadsheets and comfortable with slightly advanced vb. Here's the code: Private Function ReadDataFromWorkbook(SourceFile As String, SourceRange As String) As Variant Dim dbConnection As ADODB.Connection, rs As ADODB.Recordset Dim dbConnectionString As String dbConnectionString = "DRIVER={Microsoft Excel Driver (*.xls)};ReadOnly=1;DBQ=" & SourceFile & ";HDR=false" Set dbConnection = New ADODB.Connection dbConnection.Open dbConnectionString ' open the database connection Set rs = dbConnection.Execute("[" & SourceRange & "]") 'The source range is say A22000:IV25000 ReadDataFromWorkbook = rs.GetRows ' returns a two dim array with all records in rs rs.Close dbConnection.Close ' close the database connection Set rs = Nothing Set dbConnection = Nothing On Error GoTo 0 Exit Function InvalidInput: MsgBox "The source file or source range is invalid!", vbExclamation, "Get data from closed workbook" Set rs = Nothing Set dbConnection = Nothing End Function |
