Are you using SQL Server to handle data in an Excel sheet? Well, as you’ve noticed, even Excel itself is very bad at handling data in its own file format. At least you know that when you open an XLS file using Excel, it should open without driver problems. So do the processing outside of SQL Server. Or use a more appropriate storage for data, like an MDB file.
