I've seen a lot of questions about the best way to import data from uploaded Excel files to a SQL Server database in an ASP.NET application. Most solutions involve the use of the JET or ACE OLEDB providers to read data from the saved Excel file, and some even show how to use Office Interop to obtain the data. However, all of these solutions rely on additional components being installed on the server, and they also require the uploaded file to be saved somewhere, even temporarily, which creates an additional maintenance task. The solution that follows makes use of a Nuget package that gets deployed with your application and can work with streams, so the uploaded file doesn't need to be saved. It is, in my submission, THE best way to import data from uploaded Excel files to SQL Server in an ASP.NET application.
