The Microsoft Jet database engine could not find the object 'Sheet1$' - asp.net

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.

Answer 3

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.

Answer 4

Not sure, I have some similar code (C#) that works well...
Maybe you can spot a difference?
string connectionString = string.Format(Thread.CurrentThread.CurrentCulture, "Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties='Excel 12.0;HDR=YES;'", excelFilePath);
DbProviderFactory factory = DbProviderFactories.GetFactory("System.Data.OleDb");
using (DbConnection connection = factory.CreateConnection())
{
connection.ConnectionString = connectionString;
using (DbCommand command = connection.CreateCommand())
{
command.CommandText = #"SELECT [File], [ItemName], [ItemDescription], [Photographer name], [Date], [Environment site] FROM [Metadata$]";
connection.Open();
using (DbDataReader dr = command.ExecuteReader())
{
if (dr.HasRows)
{
while (dr.Read())
{
.......
}
}
}
connection.Close();
}
}
Try renaming your sheet; or explicitly adding columns; or checking if it's case sensitive.

Answer 5

Change your Excel file location, this error will be resolved.
may put your file in the same folder where your source present

C# My expected solution below
string connString = "Driver={Microsoft Excel Driver (*.xls)};READONLY=FALSE;DriverId=790;Dbq=" + "C:\\Users\\BHARAVI\\Documents\\visual studio 2013\\Projects\\ERP\\ERPAutomation\\Assets\\Data\\Data.xls";
OdbcConnection conn = new OdbcConnection(connString);
conn.ConnectionTimeout = 500;
OdbcCommand CMD = new OdbcCommand("SELECT * FROM [Sheet1$]", conn);
OdbcDataAdapter myDataAdaptor = new OdbcDataAdapter(CMD);
DataSet ds = new DataSet();
myDataAdaptor.Fill(ds ,"Sheet1");
DataTable dt = ds.Tables[0];
foreach (DataRow dr in dt.Rows)
{
loginId = dr["LoginId"].ToString();
encryptedPassword = dr["PWD"].ToString();
URL = dr["URL"].ToString();
}
