The Microsoft Jet database engine could not find the object 'Sheet1$'

Question

I'm attempting to read a spreadsheet file called Book1.xls which contains a worksheet called Sheet1

However I'm getting the following error:

The Microsoft Jet database engine could not find the object 'Sheet1$'. Make sure the object exists and that you spell its name and the path name correctly.

Here is a snippet of the code I'm using:

Dim dt As DataTable = New DataTable()
Select Case fileExt
    Case ".csv"
        Dim reader As New CsvReader
        dt = reader.GetDataTable(filePath)
    Case ".xls", ".xlsx"

        Dim oleDbConnStr As String
        Select Case fileExt
            Case ".xls"
                oleDbConnStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & filePath & ";Extended Properties=""Excel 8.0;HDR=Yes;IMEX=2"""
            Case ".xlsx"
                oleDbConnStr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & filePath & ";Extended Properties=""Excel 12.0;HDR=Yes;IMEX=2"""
        End Select



        Using oleDbConn As OleDbConnection = New OleDbConnection(oleDbConnStr)
            oleDbConn.Open()

            Dim oleDbCmd As New OleDbCommand("SELECT * FROM [Sheet1$]", oleDbConn)
            Dim oleDbDa As New OleDbDataAdapter(oleDbCmd)
            oleDbDa.Fill(dt)

            oleDbConn.Close()
        End Using



End Select

I can't understand why the code cannot find my worksheet. Why is this, and how can I resolve it?

Answer 1

I've found the problem.

It seems the spreadsheet was being saved to the wrong location, so filepath wasn't pointed to a file which exists.

I didn't check this at first because I assumed a different error message would appear. Something like "Book1.xls could not be found". However it seems like if it doesn't exist, then the message will just state that it cannot find the Worksheet.

Answer 2

If file name has additional dot character like below:

sample.data.csv

next select statement:

SELECT * FROM [sample.data.csv]

with connection string:

Provider=Microsoft.Jet.OLEDB.4.0;Data Source="C:\Data\"; Extended Properties="text;HDR=Yes;Format=Delimited;";

will fail with exception:

Additional information: The Microsoft Jet database engine could not find the object 'sample.data.csv'.  Make sure the object exists and that you spell its name and the path name correctly.

Also - make sure you don't have the file open in Excel already. You won't be able to read the file if it's open somewhere else. I had the same error and realized I had the file open in Excel.
