System.Data.OleDb.OleDbException: Could not find installable ISAM

Question

I have scoured the net, and found many people asking this, yet none have fixed my answer.

I have a Connection Class, and a Method that uses that Class in a page.

Answer 1

If you use more than 1 extended property then the value tokens must be quoted, otherwise there is no way for the driver to distinguish them from the other non-extended properties in the connection string;

...Extended Properties=""Excel 8.0;IMEX=1"""

modify your connection string

String.Format(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=pricelist.xlsx;Extended Properties=""Excel 12.0 Xml;HDR=YES""");
