Yes - use the ADO Jet drivers
VB code here

Its easy to adapt to VB.net/C# - the workbook needs to be closed
otherwise you'll leak a ton of memory

Hi,

I would like to know that, Is it possible to use Excel sheet as a source
(dataset) and use it against a .net client application (VB.NET) and have all
CRUD operation on data. The excel data will have one key column which will be
used as identifier. I am wondering whether is this possible.

If Yes, any pointer in that direction and how to implement required code
base using libraries will be of great help. Thanks!
