Issue while establishing connection with excel

Question

The below connection string establishes connection with excel file which has extension as '.xls' but same string throws an exception while opening a connection with file which has extension as .xlsx.

Any idea?

ConnectionString = Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\Users\abcd\Desktop\demo.xls; Extended Properties=excel 8.0; Persist Security Info=False

Answer 1

This is because you need a different connection string for xlsx'es.
