Extracting Excel data using Sql connection string - sql

Question

My intention here is to render the excel data in a table, using a datatable, so opened an odbc connection and loaded the datatable like this:
System.Data.Odbc.OdbcConnection conn = new System.Data.Odbc.OdbcConnection(Dsn=Excel Files;Driver={Microsoft Excel Driver (*.xls)};Driverid=790;Dbq=C:\Users\*******\Documents\Book1.xlsx;DefaultDir=C:\Users\******\Documents;HDR=YES);
conn.Open();
DataTable dataTable = new DataTable();
string con = "select * from [sheet1$]";
System.Data.Odbc.OdbcCommand cmd = new System.Data.Odbc.OdbcCommand(con, conn);
System.Data.Odbc.OdbcDataReader dr = cmd.ExecuteReader();
dataTable.Load(dr);
But insted getting an error like this
ERROR [IM014] [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application
So actually whats' the root cause ?

Answer 1

Please use the following link as a possible solution to your problem:
ERROR [IM014] [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application

Answer 2

This suggests
"changing the Platform target project setting from Any CPU to x86."
will help. The root cause is, as the error says, a mismatch between the database driver and your application.
These docs say
If you use the 64-bit odbcad32.exe to configure or remove a DSN that
connects to a 32-bit driver, for example, Driver do Microsoft Access
(*.mdb), you will receive the following error message: The specified
DSN contains an architecture mismatch between the Driver and
Application To resolve this error, use the 32-bit odbcad32.exe to
configure or remove the DSN.
