File Upload Tools for SQL Server

Can anyone suggest tools which can upload a variety of files (csv, xls, etc.) to SQL Server?

I can create similar tools in .net but want to save开发者_如何学运维 time on it and would rather buy a tool which can validate the file for the correct data types, required columns, etc.
