Reading an Excel File From C#

Question

I have a connection string to read an excel file from my C# project that looks like this..

String ConnectionString  = \"Provider=Microsoft.ACE.OLEDB.12.0;\"          


        

Answer 1

I think your connection string is formatted wrong and the "Could not find installable ISAM" is usually an indication of this.

Try this, it's from a piece of operational code I have:

Excel 2007

string connectionString = string.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=\"Excel 12.0 Xml;HDR=No;IMEX=1\";", fullPath);

Excel 2003

string connectionString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0; data source={0}; Extended Properties=\"Excel 8.0;HDR=No;IMEX=1\";", fullPath);
